The perfect top soundproof

Before choosing an approach to insulation you need to visit where does the noise originated from: this is effective as a way to see list of positive actions as a way to slow up the noise: maybe the noise is arising from outside including your windows are not that good and should change them, or maybe you should soundproof your walls or your floors. You will not want to pay out your hard earned dollars on a problem!
For starters you have to check your windows – in earlier times windows were to manufactured to keep noise out and maybe you ought to change them.

You can find double paned windows on your home, or you can even buy certain windows that create a polymer frame – these ones are engineered for noise reduction. Another solution would be to buy new drapes, like those that are suggested in hotels. They can be very helpful plus theyre not expensive either.

If this is not why its happening, we recommend one to insulate your walls along with your floors: you should utilize layers of drywall, soundproofing foam or soundproofing vinyl.

Does Soundproofing Foam Work To Block Noise?

Understanding the difference between soundproofing and sound absorption 

Here at
The soundproofing store we get inundated with enquires regarding soundproofing and the best way to do this.

Whether it be soundproofing against noisy neighbours, or building your own home studio we are always asked the same question regarding soundproofing foam. “Is is good for Soundproofing?”

The short answer is
No.

Unfortunately egg box type foam does not stop sound transferring through your wall from your neighbour or from leaving your room. All it will do is absorb some of the sound within your room and stop it echoing and amplifying.
It will not block sound from neighbours or escaping out of your room.

To soundproof a room we need to address the blow points.

Sound (noise) is normally broken down into two categories.

The most common is
airborne noise such as people talking and TV noise; the second is
vibration impact noise such a machines vibrating against the wall and live musical instruments

 

To soundproof a wall effectively you need to:

 

  • Improve the
    mass of the wall – This is normally achieved by adding different high mass/density products.

However, when sound hits a wall it turns in to a vibration and an energy, so Mass alone will not solve the problem. You also need to:

  • Use
    different materials of high mass. Different materials perform better for different sound frequencies, so using a combination of high mass materials will always perform better than simply using more of the same material.
  • For louder more powerful sound energy you also need to
    decouple the new wall from the existing wall because the vibration created from this is too strong to block by connecting onto the existing structure.

So why do people buy soundproofing foam and use it? What’s the point? Why do I see it on walls in images of loud music studios? 

Answer: It is there to improve the internal rooms internal acoustics. Essentially it helps to reduce Echo and Reverb within a space.

Imagine being in a room with hard surfaces, a sports hall, or village hall for example. Clap your hands in a room like this with hard surfaces and the sound appears to reverberate and echo around the space for ages. 

Do the same in a room with lots of soft furnishings and the reverberation is very limited and appears flat, with a very short continuation. 

Now imagine very bouncy basketballs being thrown around the room. You throw them everywhere, in all directions and they continue to bounce around the room.

Now imagine the walls, floor and ceiling lined with foam. You throw the balls again, only this time they hit the foam and drop to the floor stopping them from continuing to bounce, the energy from the ball has been absorbed by the foam. 

This is no different to a soundwave inside a room, it reflects and bounces off any hard surfaces, but will be absorbed by soft surfaces. This is when the ProSound room acoustic treatment systems are used. They absorb the sound and stop the reflected sound travelling back into the room.

Room acoustics BEFORE installing ProSound™ Sound Absorption Panels

Room acoustics AFTER installing ProSound™ Sound Absorption Panels

The soft material used in the panels are designed to absorb sound energy and stop this energy from bouncing around the room and reflecting off the surfaces.

Class A panels like the ones at The Soundproofing Store are tested to absorb 90-100% of sound energy that hits them. This means you require less panels in an area to achieve good results compared to lower performing foam tiles where nearly the whole surface needs to be covered to get good results.

As a general rule of thumb we look to cover around 20- 30% of the surface area of the room.

Sound absorption will therefore improve the rooms overall noise volume and improve the clarity of the sound in the room. However, it does not ultimately stop the sound energy within the room from travelling through the structure to a neighbouring space.

There are many way of applying sound absorption to a situation and some of the most popular options are our

Ceiling Rafts and
Suspended Baffles

Reducing noise | Smarter Homes

Why reduce noise?

Sound insulation of residential buildings plays a key role in maintaining people’s wellbeing.

The amount of noise in and around a home will differ, depending on the building’s location, design, construction and type – detached house, townhouse, multi-unit complex or apartment building. Noise can be a major issue for people, especially if there isn’t enough sound insulation between properties.

Requirements

In New Zealand, sound insulation regulations for buildings are specified in clause G6 of the New Zealand Building Code. These regulations dictate the minimum airborne and impact sound insulation performance between properties that touch each other – side to side, above and below (called abutting residential tenancies). Some people may prefer to exceed the Building Code requirements for better sound insulation.

Building Code Clause G6 on MBIE’s Building Performance website has more information.

Depending on where you live, your council may have additional external sound insulation requirements in the district plan, for example, if your house is in a particularly noisy area.

You can check with your local council for additional external sound insulation requirements by talking with one of their planners.

Property owners also have an obligation under the Resource Management Act to avoid making unreasonable or excessive noise.

This section will tell you what to look for concerning noise and sound insulation, whether you’re buying or renting, renovating or building new, and what you can do to reduce noise around your home.

What to look for when buying or renting

When you’re looking at buying or renting a property, ask the real estate agent or landlord questions about the noise of the surrounding environment. You should also pay attention to noise while you are looking around. Think about the time of day, noise level and types of neighbourhood noise as well as the building’s design in relation to internal and external noise.

Controlling noise is often a trade-off with other priorities, and your decisions may depend on what you are willing to put up with. It might also be useful to know what you can and can’t change – sometimes the design of a property can mean there is not a lot that can be done to reduce some noise.

If you can, look at the house at different times of the day. Try to visit when there are just a few people present as well as in the middle of a busy open home.

Try to find out:

  • How close are you to your neighbours?
  • What’s the noise like with doors and windows open?
  • What noise sources may be present? (You may not want to be shut inside in the middle of summer trying to block out neighbourhood noise.)

Common external noise sources

  • heat pump outside units, which can be quite noisy – whether it’s yours or a neighbour’s
  • swimming pools, spas or hot tubs can be loud (noise typically comes from pumps and can be ongoing)
  • kitchen extracts (including the neighbour’s)
  • non-residential neighbourhoods or thoroughfares, including central business areas, high traffic volumes, port or airport, trucks, trains, bars, restaurants, commercial neighbours, churches, sports fields, childcare centres and schools.

Common internal noise sources

  • central waste water or plumbing
  • central air-conditioning
  • lifts
  • a gym or movie theatre
  • common corridors – you’ll need to use a lobby to deal with loud noises from corridors as a door won’t block out all the noise from a corridor)
  • noisy businesses or activities in mixed use developments (for example, a bar or gym under an apartment building)
  • in flatting situations or family environments you need to think about how you will use a space and if these activities will be affected by the noisy use of a neighbouring space.

Insulation

Is there fibre-based insulation in external and internal walls, roof cavity and floor? You could ask the agent or landlord if the house has been sound insulated or if it was designed to deal with any particular noises.

If you’re getting a professional to do a building inspection of the property, this might involve them inspecting wall, floor and ceiling cavities and looking at the wall or floor structure, linings, insulation, glazing, materials and detailing. If you had serious concerns, an acoustician could measure the sound insulation.

Fibre-based insulation includes materials such as wool, fibre glass and polyester. Having fibre insulation in wall, floor or ceiling cavities can significantly improve sound insulation. This should have a minimum density of 9.8kg/m3.

Typically, R1.8 thermal insulation will do the job and there is little acoustic benefit in using greater density insulation. For the same money, you will probably get greater sound insulation performance by adding additional internal linings to your walls, ceiling or both. However, you will need to get a building consent before modifying an inter-tenancy wall.

This does not include polystyrene, which can be good for thermal insulation but is acoustically transparent (it doesn’t reduce noise). In some cases, having polystyrene installed is worse for sound insulation than an air gap.

Floors

Consider whether the floors are ‘bouncy or drummy’? If the property is multi-storied, get someone to move around upstairs while you listen below. Is this noise going to upset your sleep, relaxation, conversations, TV watching or enjoyment of the space below?

Windows

Are the windows double-glazed or laminated? Generally, the thicker the glazing and the bigger the air-gap between panes, the better the sound insulation of the window.

Double-glazing provides a small improvement for reducing mid and high frequency noises, but if the property has low frequency noise, such as from planes and trucks, etc, talk to an expert for advice (acoustician) as double glazing may not be the best solution.

7 Best Acoustic Foam Panels for Your Home Recording Studio

It is a nice feeling to escape to the peaceful environment of your home recording studio. Design your home recording studio to use the proper sound treatment to get the sound you like and then enjoy rich sound recordings.

In this post, I look at the best sound treatment materials that you can use to make your home studio a wonderful audio recording environment.

My Top Pick

Top Features:

  • 12 inches square
  • 2 inches thick
  • 2 colors of blue and charcoal
  • 12-pack with six of each color
  • Attractive checkerboard pattern with strong sound absorption.

Check price →

The Pro Studios Acoustics Wedge Foam is My Top Pick because it comes in a 12-pack with six panels in blue and six panels in black that you can mix and match in your studio. At two-inches thick, it provides the strong soundproofing that most studios need. Thanks to the low price, you can easily get as many as you need.

Also Great

Top Features:

  • 24 inches by 48 inches
  • 2½ inches thick
  • Colors of charcoal, burgundy, and red
  • 2-pack or 4-pack available
  • Reducing sound reflections in a studio room to get rid of unwanted reverb and echo

Check price →

Almost as great as my top choice is the Foamily Egg Crate Acoustic Panels that are 2. 5-inches thick. Not only can you choose packs that come with two or four panels, but you can select from three different colors to match the vibe and atmosphere of your studio.

My Top Picks:

  1. SoundAssured Acoustic Studio Foam →
  2. IZO Acoustic Egg-Crate Tiles →
  3. Pro Studio Acoustics Wedge Foam →
  4. JBER Pyramid Acoustic Foam Panels →
  5. Mybecca Acoustic Panels →
  6. Foamily Pyramid Acoustic Panels →
  7. Foamily Egg Crate Acoustic Panels →

These are my reviews of acoustic foam panels that come in different shapes, sizes, colors, and package quantities.

1. SoundAssured Acoustic Studio Foam →

These acoustic-foam panels have a wedge-style to create more surface area for sound absorption.

Characteristics

  • They come in a four-pack, with over a dozen attractive colors to choose from.
  • The dimensions are 12 inches by 12 inches square by two inches thick.
  • Fire-retardant with a rating of ASTM E 84.

What’s special about them?

  • It is easy to calculate how many packages you need to cover your home recording studio walls. Just measure the square footage of the wall space and then divide by four, since each package covers four square feet.
  • These panels are very easy to install. You can trim them as needed with regular scissors. Installation can be permanent by using adhesive tape or spray (sold separately) or you can use push pins or Velcro to hang them temporarily.
  • This product absorbs mid to high frequencies.

Best for: moderating sound deadening and it is useful to control or remove echoes.

In this video, Josh the MusicTechHelpGuy discusses the installation of these acoustic tiles in his home studio. They also come in one-inch, two-inch, three-inch, and four-inch-thick versions for different applications. The thinner tiles absorb high frequencies better. The thicker tiles absorb low-end frequencies better.

The takeaway from this video is how to use these tiles to get rid of room echo and reverb. A good tip is to make sure to cover the corners in the room because those wall angles are a source of undesirable flutter echo.

2. IZO Acoustic Egg-Crate Tiles →

These foam tiles have an egg crate design that absorbs sounds to prevent noises from leaving the studio.

Characteristics

  • Two inches thick, when measured from the peak of the tip of the foam to the base.
  • Variety of sizes of 12 inches to 36 inches.
  • One color of charcoal gray.

What’s special about them?

  • The egg-crate design is very efficient for sound absorption.
  • You can easily attach the soundproofing tiles to your walls or ceiling
  • The two-inch thickness reduces reverb and reflections, especially in the mid- to high-frequency range.

Best for: covering the ceiling, especially if it is not parallel to the floor because of the angular reflection of sound that will be bouncing back from the ceiling to walls. The lightweight nature of foam makes it easy to apply acoustic tiles to the ceiling or any other surface.

This video is by Caleb from DSLR Video Shooter focuses on improving a home recording studio to improve the sound quality for video recording. There is an explanation of the difference between soundproofing and sound treatment, how sound travels, and how sound is picked up by a microphone.

The takeaway from this video is that it shows a lower quality product than the Pro Studio Acoustics – Wedge Foam Tiles. It shows how they ship in a highly-compressed manner, which does smash them up a bit.

4. JBER Pyramid Acoustic Foam Panels →

You can hear the difference when using this foam properly as a sound treatment. You will be amazed about how much sound improvement is possible with just a few of these acoustic sound panels.

Characteristics

  • These foam panels are two-inches thick and have a pyramid-cone shape.
  • They come in a 24-pack in three colors of charcoal, blue, and red.
  • They are 12 inches square.
  • They add modest soundproofing to reduce outside noises.
  • They ship compressed.

What’s special about them?

  • You can choose between six-pack and 24-pack options based on the size of your studio.
  • They reduce both echos and background noises.
  • You can cut and shape the panels without affecting their noise reduction.

Best for: home studios to help reduce reverb, flutter echo, and unwanted reflections.  Use them to cover a wall or for spot sound treatment of special areas.

This video by EXOcontrato shows how to use acoustic sound panels with the technique of spot treatment. Spot treatment is using the acoustic panel to block reflection and modify the sound patterns in a room. To use this technique he uses a mirror to determine where the wall will reflect sound toward where the listener will be sitting.

The takeaway from this video is, you can use acoustic sound panels to fine-tune a recording studio or home entertainment room without fully covering all the walls.

5. Mybecca Acoustic Panels →

These acoustic panels are a wedge-style that can be used in a checkerboard pattern that alternates the alignment of the wedges.

Characteristics

  • They are 12 inches square.
  • They are a cost-efficient price because they come in a pack of 48 panels.
  • One pack offers coverage of 48 square feet.

What’s special about them?

  • Like all quality acoustic panels, they eliminate standing waves, reduce undesired sound reflection, and help reduce outside noise.
  • Examine all the hard surfaces in a room. Those will reflect sound. The echoes will cause recordings, especially of voice-overs, to sound strange and somewhat hollow. Covering reflective surfaces with these panels will reduce or eliminate these problems.
  • The panels reduce between 80 and 90% of typical background noises and sounds.
  • They are compliant with all flammability standards.
  • You can use the panels in small and large spaces.

Best for control rooms, recording studios, and vocal booths.

The product manufacturer, Mybecca, produced this video to show how easy it is to install these acoustic tiles using spray glue. Be aware that if you do not own the home, you may have to return the place to its original condition when moving out. For a rented home, consider mounting these acoustic tiles on cardboard and then hang the cardboard on the wall, in such a way that it does not cause any damage.

The takeaway from this video. Gluing panels on a wall is a more permanent solution. Be sure you place them properly, where you want them. Depending on the type of adhesive used, it can damage a wall or leave some residue of glue or bits of foam on the wall, when you pull the tiles off.

6. Foamily Pyramid Acoustic Panels →

Enjoy the soundproofing and elimination of background noises that you need with these pyramid acoustic panels.

Characteristics

  • They measure 24 inches by 48 inches by two inches thick.
  • They come in a two-pack with the choice of blue, red, and burgundy colors.
  • Opened cell, in a convoluted “egg crate” pattern

What’s special about them?

  • The panels meet flammability standards and passed smoldering tests.
  • They are among the only acoustic foam panels made in the United States.
  • These panels have a high NRC rating, which makes them a superb choice to cover a portion of a wall that causes unwanted sound reflections.

The NRC rating is the noise reduction coefficient. It is a single number that ranges from zero to 10. At zero NRC, there is no noise reduction and the surface is very reflective. At an NRC of 10, all sound is absorbed. At an NRC of eight, the material absorbs about 80% of the mid-frequency sound. Any NRC around eight is excellent.

Best for: spot treating areas where you need a little more soundproofing.

This video from Uncle Jessy shows how to install acoustic sound panels on the ceiling. The ceiling in a home recording studio usually is a very large reflective surface. By installing acoustic panels, this helps absorb some sound that hits the ceiling. Acoustic sound panels are very lightweight. They are easy to install on the ceiling using spray glue for permanent installation. Alternatively, use pushpins to remove them easily without leaving any visible damage.

The takeaway from this video is that a home recording studio sounds much better for voice-over recordings, when sound absorbing panels are on the ceiling for adequate sound treatment. This is true, even if the floor has carpet on it.

7. Foamily Egg Crate Acoustic Panels →

Choose from both the colors and sizes that you need to make these panels fit your studio.

Characteristics

  • These large sound absorbing panels measure 24 inches by 48 inches and are two and one-half inches thick.
  • They come in the colors of charcoal, burgundy, and red.
  • There is a two-pack or a four-pack available.

What’s special about them?

  • Some sound recording engineers prefer the look of the egg-crate design and its softer, rounded edges when compared to a pyramid style.
  • Does a good job of absorbing sounds and noises to help you hear and record clearly.
  • I am not able to notice much difference between style design of the Foamily products; however, these panels are one-half inch thicker than the two-inch acoustic panels. The thickness makes a difference in capturing sound. Using thicker panels, with denser foam, is usually better.

Best for: reducing sound reflections in a studio room to get rid of unwanted reverb and echo. This product does not do much soundproofing. The volume of the sound will not change significantly. However, the quality of the sound will improve. This is the same for all acoustic tiles in this category.

This video by David Day from AdoramaTV has an excellent explanation about unwanted sound reflections and how they are usually the cause of poor audio recordings, not the recording equipment, the microphone, or the playback monitors. He also describes how sound waves collide and interfere with each other to cancel out sound and change the sound.

The takeaway from this video is to use acoustic tiles to absorb sound. He shows how to determine the best placement for your sound absorbing panels by using the help of a friend and a mirror to see where sound may be reflecting in the room.

Guide

Here is a guide about important topics to understand and consider for the sound treatment of your home recording studio.

Sound Treatment is Not Soundproofing

Sound treatment is different from soundproofing. The goal of soundproofing is to block sound transmission from one place to another one. I giggle at the silliness when I read complaints that people try to block the sound of a neighbor’s dog barking by putting these acoustic panels to hang in front of their windows. That will not work at all. Soundproofing is a reconstruction project because soundproof foam does not exist.

Soundproofing is a completely different endeavor. It is much more expensive and requires substantial changes in the room design including renovation and major construction. You need very thick, heavily insulated, concrete walls to achieve 100% soundproofing. There is no comparison with hanging a few foam acoustic panels on the walls. If your goal is soundproofing, this guide is not going to help you.

You need to learn more about blocking sound compared to absorbing sound. Soundproofing is blocking sound and that means completely stopping vibrations, not changing the quality of the sound by absorbing a part of it.

Acoustic panels are for the sound treatment of a room to stop sound from bouncing around the room in ways that reduce the quality (not the volume) of the sound. Think of these as fine-tuning the room to keep reflected sound from bouncing off hard surfaces and coming to your ears more than once in distorted ways that make it sound bad. Sound treatment is the fine-tuning of your home studio to make the room sound more clean and clear.

How to Choose Acoustic Foam Panels

The considerations for the acoustic panels include a choice of sound absorption, thickness, size, and design.

To get better quality acoustic panels, look for a high number (in the range of one to 10) for the noise reduction coefficient (NRC) for better sound absorption. The recommended NRC for a home studio is around eight. Be aware that the NRC is only a measurement of the absorption of the mid-range sound. If you are having trouble with the bass sound in your home recording studio this NRC number is meaningless for bass frequencies because it does not measure them.

The recommended thickness is two inches. Denser foam weighs more. You can tell if the product is better quality, with denser foam, by comparing the product’s weight (not including the shipping packaging weight) with another product that covers the same amount of square feet.

The design style of the foam is a matter of personal choice. If they are the same quality, there is not much of a difference between panels that are wedge style, pyramid style, or egg crate style. The only difference in style that makes a significant difference is a panel designed for capturing low frequencies. Accomplish this by using another product designed specifically to absorb bass frequencies. These specialized “bass traps” install in the corners of the room and the ceiling corners, where bass sound tends to collect. They are thicker, have more angles, and fit in a corner well.

How many acoustic panels do you need?

Use this handy acoustic panel room calculator to enter the length, width, and height (in feet) of your home recording studio to get the number of recommended panels. Please note that in most home recording studios you do not want 100% coverage. You will get better sounding results with a sound treatment that provides 60 to 80% coverage.

The results given by the calculator include a light treatment recommendation for living rooms, conference rooms, or workout rooms. It gives a recommended treatment for most sound rooms, which is good for home studios. It also gives a recommendation for heavy sound treatment for professional recording studios. This calculator tells you the number of panels needed for three sizes of panels that are two-feet square, two by three feet, and two by four feet.

How to Choose Correct Panels Positioning

There are two ways to choose the positioning of acoustic panels for a home studio. The basic way is to use a mirror to imagine the direction of the sound reflections. Doing this mirror technique with the help of a friend makes it easier. The other way is to use a professional audio testing system that shoots sharp sounds out of a handheld transmitting device while recording the sound as it bounces from the room surfaces. Then, the software makes some calculations and presents a wave pattern of the sound, used by a professional audio technician to make room adjustments.


You can see this audio testing equipment used in the tutorial video above – How to Set Up, Test and Improve Your Home Music Production Studio Room. In this video, the instructor converts a regular bedroom in a house into a home recording studio from scratch.

For the vast majority of home recording studios, the mirror technique is the most appropriate. Invite a friend to help you. Sit in your desk chair in front of your sound mixing table. Make sure to center the table and check if it is equidistant from both walls. Make sure your monitor speakers are at the proper height, which is at eye-level from the center point between the tweeters (high-end speakers) and the bigger mid-range speakers below them. Both speakers are together in the speaker monitor cabinets placed on your desk or stands.

Once you have the correct position for yourself, ask your friend to carry a mirror around the room to hold up to the walls. Have your friend stop frequently for you to look for the reflection of the monitor speakers in the mirror. When you see the reflection of your monitors, have your friend mark those spots on the walls. That is where sound will reflect from the sound coming out of your monitors.

If you use acoustic panels to cover a large portion of these reflective areas, you will deaden the reflections and improve the sound in the room. These are the “first reflections” of the sound. You do not have to cover the walls from floor to ceiling. Just cover a wide area of the wall about two feet up from the floor to about two feet above the height of your head when you are sitting down at your mixing desk.


Here is a video showing how to use the mirror technique for the placement of acoustic panels.

Sound Treatment of Corners and Ceilings

If you want the best sound, any corners in the room are going to need sound treatment. Sound causes flutter echoes when it bouncing back from each side of a corner. Also, consider using bass traps in the corners because bass collects in that part of the room and causes distortions in what you hear in the low-frequency range.

Sit at your sound mixing desk and look up. If you see a reflective surface, then, that part of the ceiling needs covering with acoustic tiles. Cover from where the ceiling meets the wall in front of you to about six feet behind you. This will keep all the sound that heads upward from being reflecting down to your ears. It sounds bad when reflected sound is out of sync with the sound you hear from the monitors.

How to Cut Acoustic Foam Panels

Cutting acoustic panels is easy and fun. It is like an art and crafts project. For acoustic panels that are two-inches thick, you can cut them with a nice pair of scissors. The kind of scissors used to cut fabric. If you want to cut thicker panels and make clean lines, consider using an electric carving knife like the kind you use to carve a turkey.

Mark the cut to make on the back of a panel and use the electric knife like you might use an electric circular saw. This is easier and makes neater cuts than trying to cut the foam panel with a utility knife.

How to Hang Acoustic Foam Panels

Here are some options to use for ways to hang the acoustic foam panels:

3M General Purpose 45 Spray Adhesive →

This is a popular spray adhesive that can either be sprayed on the tile, the wall, or the ceiling, and then place the tile in position. It gives a secure bond in 30 seconds and dries completely within 15 minutes. It can also be sprayed on cardboard to attach tiles to a cardboard backing, and then attach the cardboard to the surface in an easily removable way.

Loctite 2235316 General Performance 100 →

This is a translucent spray that creates a strong enough adhesive hold that tiles will permanently stay in place. The tiles will still be removable, without causing damage, even if the installation is temporary or if the acoustic tiles need to be re-positioned.

 

Gorilla Double-Sided Mounting Tape →

The convenience of this double-sided tape is that you can use as little or as much as you want. Acoustic tiles are not heavy so it does not take very much to mount them. This is a permanent solution and the hold is very strong. It may cause damage to walls if removed.

Blulu Steel T-Pins →

These steel push pins are very useful for those wanting to hang acoustic tiles in a way that does not damage walls or ceilings. These push pins come in a box of 150, which contains some two-inch pins and some one-and-one-half-inch pins.

Command Large Strips →

These strips are 0.75 inches wide by 3.65 inches long. They are strong enough to hold acoustic tiles in place and easily remove without causing any damage. They work on most surfaces.

Liquid Nails →

 

This is a very strong permanent adhesive that comes in a tube. It applies like the way you use caulking with a caulking gun. It easy to use and makes sticking the acoustic tiles in place very fast.

 

 

Box USA Corrugated Cardboard Sheets →

This product is good for those who prefer to mount the acoustic tiles on cardboard and then hang the cardboard. This method allows the cardboard backing to provide strength and stability for the acoustic tile and keep it in the correct shape. Then, hang the cardboard in a variety of ways using any
of the materials listed above.

Tips

Here are some tips that will help you with the sound treatment of your home recording studio.

Thickness

Thicker panels are better; however, two-inch-thick panels are is the best choice for a home recording studio. This is the most popular standard.

Size

Large panels are harder to mount and to replace with new ones. Smaller tiles are easier to mount, especially if you are working alone. The most flexible choice is to buy the 12-inch square or 24-inch square sizes of acoustic tiles.

Wall Surfaces

Here are the best things to use for different wall surfaces and textures:

  • Drywall and Smooth Surfaces: Use spray adhesive, double-sided tape, adhesive squares, Gorilla® mounting tape, 3M Command Strips®, or two-inch T-shaped pushpins.
  • Concrete, Brick, and Rough Surfaces: Use a construction adhesive like Liquid Nails®
  • Wallpaper or Textured Surfaces: It is not recommended to install acoustic tiles on these delicate surfaces using spray adhesive. They will not adhere well and you will cause significant damage when removing the tiles.
  • Uneven surfaces: Mount the acoustic foam tiles on cardboard to give them a sturdy flat surface to adhere to and then hang the cardboard on the uneven wall using any of the materials described above, depending on the type of wall surface.


This video tutorial shows the easy installation of acoustic panels using 3M Command Strips®. The panels are easy to place and to remove without damaging the walls.

The Sandwich Acoustic Panel

Making a “sandwich” of materials may help with the installation of acoustic panels, depending on the surface you are working with. The technique also makes the acoustic panels more portable if you need to remove them frequently, take them to another location, or have to be careful not to damage walls of rented spaces.

The basic sandwich is an acoustic panel mounted on cardboard using permanent spray adhesive. The advanced sandwich technique has more layers, which are, in order, these options:

  1. Acoustic Tile
  2. Permanent Spray Adhesive or Glue
  3. Cardboard, Corrugated Plastic Board, or Plywood
  4. Wall Surface

Make the acoustic tile sandwich, let it completely dry, and then attach the sandwich to the wall using push pins, small nails, tacks, or a non-permanent, easy-to-remove adhesive, such as 3M Command Strips®. If you prefer, use adhesive squares. Use at least three adhesive squares (two in corners at the top and one in the center at the bottom) for a one-square-foot acoustic panel or four adhesive squares (one in each corner), if the acoustic-panel thickness is more than two inches.

Here is a video tutorial about this technique:

FAQ

Q: What is the difference between soundproofing vs. sound treatment?
A: Soundproofing is much more difficult. It blocks sound by stopping vibrations from one place to another. Sound treatment changes the sound, using acoustic panels to improve quality, but does not lower the volume.

Q: What are the common shapes (types) of acoustic foam panels?
A: Acoustic panels come in three popular styles, which are wedges, pyramids, and egg crate. There are subtle differences between them; however, they all work in the same way to absorb sound and re-direct the sound waves.

Q: What is Noise Reduction Coefficient (NRC) rating?
A: The Noise Reduction Coefficient (NRC) tells how good the acoustic foam material is at absorbing mid-range frequencies. An NRC of 10 is the maximum with 100% absorption of certain mid-range frequencies. An NRC of zero is a reflective surface that absorbs no sound. A decent NRC rating for a home recording studio is around eight. A higher NRC is better. An NRC rating is only a measurement of the mid-range frequencies. It will not help problems with bass sound frequencies.

Q: What about ceiling sound treatment?
A: The sound that hits the ceiling will bounce back down to the walls and the floor. The floor’s sound absorption improves with thick carpet. Cover the ceiling area directly above the mixing station to get a better sound.

Q: What are other ways to improve sound treatment?
A: Bass traps go along well with acoustic tiles. Lower frequencies come out of the woofers and subwoofers and move in an omnidirectional (spherical pattern) way. The bass sound collects in the corners of a room and builds up until it causes a distortion problem. This means you will not be able to hear the low-end of your sound mix correctly. The solution is a bass trap like the Acoustic Foam Bass Trap Corner Wall or the Mybecca acoustic foam bass trap. For the best results, place these bass traps in all corners of the room where the walls meet and in the spots where the wall corners meet the ceiling.

Conclusion

You will be amazed at the richness of the sound that is achievable for a modest investment in time and money to use acoustic tiles for the sound treatment of your home recording studio. Combine this effort with the recommendations for voice-over equipment, microphones, and the best home studio monitors. This will make your home studio a magnificent space for voice-over recordings.

Existing Wall Insulation NZ | Noise & Acoustic Insulation NZ

Existing Wall Insulation

You don’t need to remove linings to insulate existing lined wall cavities. These can be insulated by drilling and filling holes through the external or internal lining with either a water repellent dry fibre or wet foam system. With either existing wall system there are usually three to four 25-30mm holes drilled in the wall, about every 500mm around the building.

existing wall insulation

Total R-value (installed) of R2.1 -R2.6 is achieved in a typical 90-100mm wall cavity with water repellent dry fibre or R1.0 – R1.5 with wet foam system installed correctly.

Unplastered or unpainted brick veneer cavities should be sealed first with either system, due to the high potential of wind driven rain entering such unsealed cavities.

CosyWall is a dry, water-repellant, mineral fibre existing wall insulation system, which is installed at the optimum design density to prevent settlement and ensure that the Total R-value is achieved and maintained. With the CosyWall system holes are plugged with filler immediately after the insulation is installed, then sanded, primed and finish coated.

CosyWall water-repellent, dry, mineral fibre system tests indicated no wicking after 30 days and no settlement after six months at the design density. CozyWall insulation prevents potential fire spread in the cavity and reduces noise transmission through the walls.

Wet foam systems are usually manufactured on site from urea formaldehyde chemicals and water, or occasionally urethane foams. Installation of these systems is more complex, which often means long-term that the Total R-values (installed) are considerably less than that stated by suppliers.

Wet Foam wall Insulation

The wet foam process requires 25-30 days full home ventilation to aid curing and reduce formaldehyde levels. Ideally, the home should not be occupied during this period. External wall hole plugging should not be completed until full curing is complete and internal wall moisture content is less than 24%. Serious concerns about the suitability of wet foam for existing wall cavities have been raised by Department of Building & Housing (Determination report 2008/35) and BRANZ (reports SR233 and SR234), which are available on their respective websites.

Wet foam holes should be plugged with a glued timber plug, then filled, sanded and primed. Finish painting should be delayed until all moisture introduced with wet foam has evaporated.

Branz report SR233 states 6% perimeter and thickness shrinkage from framing timber as the foam cures – which reduces the manufacturers claimed R2.9 to a Total R-value (installed) of R1.0 – R1.6

Wet foam systems can reduce potential fire spread in the wall cavity (depending on edge gap extent) and act as a cavity noise absorber.

Tranquility in mind

SoftSound was developed with tranquility in mind. Together with ensuring it is lightweight so you can install it with confidence, knowing it’s proven performance, but not adding significant weight that you have to push through the water, costing fuel or speed when sailing. SoftSound is manufactured with a foil faced polyester sound absorption blanket, and a self adhesive sound barrier backing.

The sound absorption blanket is lightweight but high density (35kg/m, and 50mm or 25mm thick) acoustic/thermal insulation material manufactured from thermally bonded polyester with perforated foil (approx 10% free area) or acoustic non-perforated foil laminated to one side. The sound barrier foam is a flexible, lightweight but high density acoustic and thermal insulation material (25 kg/m 5mm closed cell foam with a self adhesive backing). The sound absorption blanket and sound barrier foam, laminated together, make up SoftSound, giving it two nominal thicknesses to choose from, 55mm and 30mm.The sound absorption blanket “traps” the sound inside the polyester fibres and the closed cell foam acts as a sound barrier and is an excellent reflector of sound. It is also resistant to biological atack (bacteria and fungal resistant), and reduces drumming and provides vibration dampening.

Soundproof Foam And Acoustic Foam

I have come across many people who really believe that foam is great for soundproofing spaces such as home recording studios and bedrooms.

I’ve heard all of them mention the term ‘soundproof foam’ which blocks sound and I tell each and every one of them that there is no such thing.

It’s surprising to see so many websites and forums that profess that the cheapest and most effective material to soundproof anything, is foam.

So, as an owner of a home studio and a site on soundproofing, I feel that I have a responsibility to put the facts out there and educate people so that they don’t waste their money on something totally useless as foam.

As an affiliate, I may collect a share of sales or other compensation from the links on this page.

Here is the bottom line:

Foam does not work effectively for soundproofing as it has insubstantial mass to BLOCK sound whereas it is highly capable of ABSORBING sound. That is why ‘acoustic foam’ is for real and ‘soundproof foam’ is a myth.

The Soundproof Foam Myth

The misconception about foam being soundproof exists mostly because people lack the understanding of the differences between sound absorption and soundproofing.

It is natural to assume that if products like foam absorb sound, there will be none that is left to escape the room.

Unfortunately, sound is not like a fluid that gets absorbed and trapped in something like a sponge. The way sound behaves needs to be understood clearly here.

Sound waves are nothing but vibrations and when they strike a surface, they tend to vibrate it.

Sound does not ‘pass’ through a wall or ceiling but merely vibrates it. These vibrations are further transferred to the other side and that is how sound transfer takes place through walls, ceilings, and other surfaces.

What’s a Good Soundproofing Material

Now that we are clear on how sound transfers through surfaces, it is important to know what the basic requirements are for a product to reduce sound transfer.

As I brought out before, sound waves vibrate a surface when they strike it and the intensity of vibrations of the surface determines how much sound is transferred.

So, naturally, we want the surface to resist the vibrations or not allow sound waves to vibrate it.

For this to happen, the object needs to be dense and heavy. A heavy wall, for example, would be difficult to move.

Now it’s easy to see that foam is not good for soundproofing. Ask yourself, how heavy is the densest of foam that you’ve come across?

Not much really and the answer lies in this. Foam can never be made heavy enough for it to become an effective soundproofing substance to reduce sound transfer.

I would like to bring out some of the myths regarding ‘soundproof’ foam and what you should do instead, for actual soundproofing.

After that, I’ll talk about the acoustic capabilities of foam.

1. Walls and Ceilings

The most common myth is that panels made of foam can be stuck on walls and will reduce the amount of sound from entering or leaving a room.

The foam that you see stuck on the walls of studios is not meant for soundproofing but is meant for sound absorption. The products that do the actual soundproofing in a studio are something else.

What You Should Be Doing Instead

You should first of all try to make your walls heavier. You can add mass to your wall by:-

Extra Drywall

Installing an additional layer or two of drywall will help to reduce sound transfer. A 5/8” thick drywall sheet weighs 2.31 pounds per square foot. That’s some serious mass and is a great substance for reducing sound transfer.

Coming back to foam, there are many varieties available and their densities vary depending on the type and grade. However, the foam would have to be several inches thick to match the mass of drywall.

Pros

Cons

  • Effort and workmanship required to install.
  • Involves modification of structures, so not an option for rented apartments.

Mass Loaded Vinyl (MLV)

Unlike foam, mass loaded vinyl is flexible and is dense as well. It is a great way to reduce sound transfer if you don’t want to get into the hassle of installing drywall or you live in a rented apartment where you are not permitted any structural modifications.

Again, the typical ‘soundproof’ foam is no match for the mass of an MLV.

Pros

  • Easy to install.
  • Higher density and mass.
  • Can be used for rooms where installing additional drywall is not feasible.

Cons

Damping Compound

Image source: greengluecompany.com

Using a damping compound like Green Glue is a smart way of increasing the effectiveness of soundproofing.

The damping compound will be sandwiched between the existing wall or ceiling, and the drywall or mass loaded vinyl that you are installing.

Pros

  • It does not require additional space as it is a fluid that will be sandwiched between two hard surfaces.
  • Cost-effective.

Cons

  • Adds to the overall cost.
  • A bit messy which applying.
  • Long curating time.

To know about the effectiveness of Green Glue, I highly recommend you read my article.

2. Floors

When you’re trying to soundproof a floor, there are two issues that you would be looking at.

  • Impact Noise
  • Airborne Noise

Impact noise is the noise caused as a result of footsteps or furniture being moved on the floor.

Airborne noise is the sound that is normally transmitted through the air and these include traffic noise, dog barking, neighbors yelling, and everything else.

What would foam do for floors?

Having a foam layer laid out on the floor would help a little in reducing impact noise. How much the effect would be would largely depend on the thickness and density of the foam.

For airborne noise or sound transmission through the floor, foam is ineffective. The same rule of an increased mass requirement would rule out foam as an effective substance for soundproofing.

In this video, the ineffectiveness of spray foam for soundproofing is clearly demonstrated.

Does Spray Foam Soundproof a Floor? Lets Test it!

What You Should Be Doing Instead

Drywall on the floor is impractical, so that can be considered ruled out. However, a heavy object would deal with impact as well as airborne noise and will be much more effective than foam.

Concrete floors do well but at the same time, concrete is a good transmitter of sound despite having lots of mass.

Before you start, you will need to assess how much sound is being transmitted through the floors. The first thing you should do is to seal the gaps/cracks in your house to make a realistic assessment.

Then, if you find that the floors are a problem, you can use any of the solutions given below.

Use a Soundproof Underlayment

This is the best soundproofing option. An underlayment such as the Serena Mat with just 3/8” thickness would weigh 1.4 pounds per square foot.

Pros

  • Easy to install.
  • Made of recycled items.
  • Highly Effective (much more than foam).
  • It can be glued directly to engineered wood.

Cons

Mass Loaded Vinyl

Mass loaded vinyl can be used as an underlay as well. It has similar properties and functions to the Serena Mat except that it is made of limp mass material whereas the Serena Mat is recycled rubber.

The pros and cons of mass loaded vinyl as brought out earlier are applicable here too.

Cork Underlayment

If you don’t have the budget for a soundproof underlayment, you can go for a ‘sound deadening’ option which is cost-effective.

Cork is a very popular underlayment which is more effective than foam and yet, priced at half a buck or less.

Pros

  • Very cost-effective.
  • Easy to install.
  • It can be used for most types of floors.

Cons

  • Not as effective as MLV and Serena Mat/Acoustik Mat but far better than foam.
  • Susceptible to moisture. A plastic protective layer is required.

Read about my top recommendations for cork underlayment.

3. Doors

Though not very often but I’ve also heard of people using foam to soundproof doors. Before we dwell on this, there are three main types of doors that we will talk about here.

  1. Hollow Core Doors
  2. Solid Wood Doors
  3. Solid Core Doors

Hollow core doors are the low cost and light doors which are common in most homes and offices.

Being lightweight, they transmit sound easily. Adding so-called ‘soundproof’ foam will not add enough weight to reduce sound transfer.

What You Should Be Doing Instead

Doors are weak links and soundproofing them is a difficult task. Here is what you can do.

Communicating Doors

The best option to reduce sound transfer is to have communicating doors.

Communicating doors are a set of two doors installed with a gap in between them. The gap of air between them will create an insulating layer which will be highly beneficial for soundproofing.

A gain from 30 STC to 55 STC can be achieved by installing communicating doors. More about these in my article here.

Replace the Door

The second option is to replace the hollow-core door with a solid core door. Solid core doors are known to perform better than solid wood doors and have the advantage of being less costly in comparison.

However, it will still be inferior in soundproofing as compared to the communicating door.

Soundproof Curtains

Installing communicating doors or replacing the door would involve some time, effort, and money.

If you want to have the least of the three, ‘soundproof curtains’ as the term goes, are an option. I call them noise reducing curtains because they do deaden the sound, but don’t do wonders. And they are much better than foam.

These curtains are heavy and are effective to quite an extent but not as good as the options mentioned before. Nonetheless, it is better to have them than to have nothing at all.

Read my guide on soundproof curtains.

Whichever option you choose, you have to seal the gaps through which sound is allowed to easily enter or leave a room.

The gaps in the door frames, door jambs, and under the door would need to be plugged and this can be a painful exercise.

4. Windows

Like doors, you will find windows difficult to soundproof. Windows are thin and the glass does not help either.

Covering the window with foam panels does not help. Using expanding foam in between the cracks and gaps would help but enough to prevent direct leakage of sound.

What You Should Be Doing Instead

Sealing gaps with expanding foam or foam spray is an option but can be messy. It is better to use acoustic sealant instead.

As far as the window itself, adding mass is not easy. The following are the viable options for soundproofing a window:-

Double Glazing or Secondary Glazing

The best option would be to have a two-layered window with an air gap in between. The air gap in between will act as an effective insulating layer for sound.

The types of glass used for this are acrylic or laminated glass. For installing a double glazed window, you would have to remove your existing window.

The problem with double glazed windows is that they are costly. An alternative would be secondary glazing wherein your existing window will become the first layer and the second layer of acrylic, laminated glass or acoustically laminated glass is simply added.

Between acrylic and laminated glass, the latter will be more effective for soundproofing.

Install a Window Plug

This is a popular one among home theater and home studio owners.

A window plug is a simple way of adding mass over the window to reduce sound transfer. It is also a good way of soundproofing windows without replacing them.

A window plug is basically a box filled with insulation that exactly matches the dimensions of the window and fits in the gap over the window sill.

Details of its construction can be found here.

The substance used for the construction of a window plug is the key. MDF or OSB being dense and heavy are great options. Needless to say, a foam comes nowhere near a window plug in terms of soundproofing.

Soundproof Curtains

Soundproof curtains are a good option for windows too. They are quick and easy to install and don’t cost much. They are not as effective as double glazing or window plugs but as mentioned earlier, much more effective than foam.

For more ways (other than foam), read my article on how to soundproof windows.

5. Ear Plugs and Ear Defenders

Foam is an integral part of earplugs and ear defenders. And there is no choice really. These cannot be made of heavy stuff as they will cause a lot of discomfort while wearing.

Ear defenders are made of hard plastic on the outer and foam layers on the inside. They do provide protection against high-frequency sound but not so for lower frequencies.

The ear defenders cup the ears with pressure making an airtight chamber. This gives the impression that the foam is blocking sound well.

But, if you are traveling in an aircraft or a bus, you will hear the low-frequency engine noises clearly. The lack of mass would never make an ear defender soundproof.

Acoustic or Sound Absorbing Foam

Now that you are aware that soundproof foam does not exist, let us move on to the acoustic foam.

Acoustic foam works fairly well at sound absorption and can be used to acoustically treat a room to improve the quality of sound. It is widely used for treating recording studios and theaters.

To bring out how effective foam is for sound absorption, I would like to compare it to rigid or high-density fiberglass insulation.

There are three important differences between the two types which we need to consider while placing them in a room for improving acoustics.

Cost

Foam wedges are cheaper as compared to fiberglass insulation panels and the more popular choice for recording studios. This is because a fiberglass insulation board needs a frame to protect it from breaking and the panel is required to be covered with fabric so that the insulation fibers don’t fly off.

Foam does not require a frame or fabric as it is strong enough to withstand light stresses and does not have fibers that will fly off.

Health Concerns

Fiberglass fibers are made up of small pieces of glass extruded in fibers and are a health hazard when inhaled. More about the health hazards of fiberglass insulation here.

Precautions need to be taken while working with fiberglass insulation. Even when wrapped in fabric, there are chances of the fibers coming out through the pores of the cloth.

There are no such concerns with regard to foam and that is why foam is preferred for small recording studios.

Working with Fiberglass as Compared to Acoustic Foam

Apart from health hazards, fiberglass insulation also causes irritation when it comes in contact with the skin.

No such problems with foam whatsoever.

Sound Absorption

The fiberglass loses on all counts to foam but is the winner as far as the most important factor is concerned.

To acoustically treat a room (like a home studio), you would like to know how well the product (like foam panels) absorbs sound. The more it absorbs sound, the less of it is reflected back in the room.

An important metric for calculation of sound absorption is Noise Reduction Coefficient (NRC).

An NRC of 0 means that there is no sound absorption taking place and the product is totally useless for acoustics. On the other hand, an NRC of 1 indicates 100% absorption.

However, absorption tests also indicate values over 1 even though it is theoretically impossible for substances to absorb more than 100%. There is a technical explanation given by Ethan Winer here but for understanding purposes, NRC 1 and above mean perfect absorption.

A comparison between the NRC values of two-inch fiberglass rigid boards and two-inch acoustic foam wedges is given in the table below.

Material 125 Hz 250 Hz 500 Hz 1000 Hz 2000 Hz 4000 Hz Overall NRC
Fiberglass 2” thick 0.17 0.86 1.14 1.07 1.02 0.98 1
Foam 2” thick 0.2 0.29 0.66 0.8 0.89 1.02 0.65

As seen in the table above, the NRC values at 1000 Hz and above are more or less similar whereas at 500 Hz and below, fiberglass outperforms the foam.

Verdict

Acoustic foam will cost lesser than fiberglass, is virtually free of health hazards, and much easier to work with.

Acoustic foam can be used effectively to tame mid and high frequencies. However, they should not be used for treating low frequencies.

So, my take on this is that you should have acoustic panels made of foam for the higher frequencies and bass traps for the lower frequencies.

My advice would be this – Don’t go for bass traps made of foam no matter how many positive reviews you find for such products.

Acoustic Panel Placement Plan

A typical placement plan for bass traps and acoustic foam panels in a room is shown below.

Good places to place bass traps are the corners where the walls intersect and the places where the walls and ceiling meet. These are the areas where low-frequency bass is the maximum.

Acoustic panels will be placed at the reflection points. These are the points on the walls and ceiling where sound bounces off and reflects on to the listening position. Read this article of mine to know more about reflection points and how to find them.

The bass trap placements in corners are marked by ‘1’ and the wall-ceiling ones are marked as ‘2’. The rectangles marked as ‘3’ are for acoustic panels.

The types and dimensions of the traps and panels as given in the figure would be as follows:-

  • Rectangles marked ‘1’ and ‘2’ – Fiberglass bass traps 48” x 24” x 4” (thickness)
  • Rectangles marked ‘3’ – Acoustic Foam wedges 36” x 24” x 2” (thickness)

So, as per the figure, we would need a total of 8 bass traps and 6 acoustic panels.

Recommended Products

The products that I recommend will do a good job at a reasonable price. There are products like the super chunk bass traps which would perform marginally better but are not worth the cost.

Bass Traps

ATS Acoustic Panel 24x48x4 Inches (check prices of these products on Amazon).

These products can be straddled across each corner.

The air gap behind the panel will assist in low-frequency absorption. Read my article on bass traps and acoustic panels for a detailed explanation.

Acoustic Panels

12″x12″ Two-inch Thick Foam Wedges by Izo -12 pack (check prices of these products on Amazon).

These are two-inch-thick foam panels that come in packs of 12. Total dimensions of these wedges when placed together (see image) would be 48” x 36”.

To economize, we will be placing only six of the wedges (total 36” x 24” area covered) at each reflection point.

So, you will need only three 12 packs of these products to cover the six reflection points.

Cost Analysis

For the products recommended, let us see how much the cost works out to be. Prices would vary as they are subject to change.

8 x Fiberglass Bass Traps = $71 x 8 = $568

As you will need only three 12-pack foam wedges for the six reflection points, cost of these will be..

3 x 12-pack foam wedges = $35 x 3 = $105

Total Cost of recommended products = $673

This is still too high. To bring the costs down I would recommend going for four bass traps instead of six for the corners of the room.

The corners of the room accumulate more bass than the wall to ceiling intersections, so it’s ok to skip them for now.

This would reduce the total cost of products to $389 which is reasonable.

The cheapest alternative would be to go the DIY route.

Final Thoughts

In this article, I have tried my best to bring out the myths surrounding ‘soundproof’ foam by giving detailed explanations and reasoning.

These myths have been around for decades and it is surprising to see them prevalent in these modern times.

The biggest problem is that these myths lead to wrong decisions which prove to be costly.

Foam may be cheap but when you buy in bulk to cover your walls and ceilings and in the end, you get no benefit, imagine what a waste of money that would be.

Foam can be used for improving the acoustics of a room, but with limitations as mentioned earlier in this article. Make sure that you don’t buy foam bass traps as they will not be effective for low-frequency sound absorption.

And last but not the least, if you find the information in this article useful, do share it with your family and friends so that they don’t fall into the soundproof foam gimmick.

Thanks for reading! Before you go, take a minute out and check out the best insulation materials for soundproofing and acoustics which I highly recommend.

What is the difference between a gas block and a foam block?

These two building materials belong to aerated concrete, the main differences are in the features of the technological process, nuances of composition and small differences in operational properties.

Appearance

Aerated concrete (also called gas silicate) – white blocks with a rough surface.

Foam concrete – gray blocks with a smooth surface.

Structure

Bonolit D500 aerated concrete (left) has a porous structure with small pores, which leads to increased moisture and vapor permeability and requires a thoughtful exterior finish. In terms of thermal insulation properties, it ranks first among wall materials.

Foam concrete (right) has a closed porous structure, therefore it is moisture resistant and at the same time has excellent sound insulation properties.

Composition

The basic composition of these two materials is the same – water, fine sand and high quality cement, in fact, this is the composition of foam concrete, but aluminum powder, lime and various additives are added to the aerated concrete to improve the quality characteristics.

Production process

Aerated concrete production consists of a series of successive stages.First, the main raw materials are thoroughly mixed in a production mixer. Then, aluminum powder and water are added to the basic composition, while a violent reaction occurs with the formation of carbon dioxide. Then the material is solidified and cut into blocks of a certain size and sent to the autoclave for several hours. The finished blocks are carefully packed to prevent moisture ingress.

Production of aerated concrete is simpler, but more time-consuming. First, the ingredients are mixed, then the foam is added, the finished solution is loaded into the molds and allowed to settle for 4-5 hours.For final drying and hardening, ready-made foam concrete blocks should be stored for another 2-3 weeks, after which they are ready for use.

If you still have questions or want to visually verify the quality of these materials, to see their differences, we invite you to visit our exhibition in the city of Kolomna, where a huge range of goods is presented, and you can get highly qualified advice from our specialists.
