Sound Proof Insulation: Overview, Types, and Benefits

An Overview Of Sound Proof Insulation

  • Designed to muffle or deaden sound
  • Used to keep sounds from entering or exiting a room
  • Can be installed before or after room construction

Sound proof insulation is defined as insulation designed to deaden or muffle sound in order to lessen noise pollution. 

It can be used to keep sounds from entering or escaping a room thus making the inside of the structure peaceful irrespective of what is happening outside, or allowing people to be noisy without creating a disturbance for the neighbors. 

There are many different  sound proofing  styles that can be applied prior to and after a room has been constructed.

Types Of Sound Proof Insulation

Foam Insulation

Lead-lined foams and Sheetrock should be installed during the construction of the room in question. Otherwise, their installation would involve tearing down existing or even entire walls. 

For spaces between ½ inch and 2 inches thick, spray foam is recommended as it has a high sound transmission rating of between 40 and 50. 

The higher the soundproof insulation index, the higher its ability to absorb sound. A normal wall has an index of between 20 and 25.

The major benefit of foam is that it is sprayed directly on to the walls without having to undertake any major reconstruction. 

Vinyl Soundproofing

Variously referred to as mass loaded vinyl, vinyl sound proofing is renowned for its high sound transmission index of between 42 and 55. 

It is extremely lightweight and possesses a higher mass than what you would expect of a material extracted from such thinness. It is this quality that gives vinyl soundproofing its capabilities.

Rock Wool

With production techniques such as those used in the production of cotton candy, molten rock is spun at high speed resulting in numerous intertwined fibers with diameters ranging between 6 and 10 micrometers. 

When this material is pressed into rolls or sheets, it can absorb sound and act as an effective insulation.

Benefits Of Sound Proof Insulation

Privacy for your Family

Sound proof insulation means that adults do not have to endure the loud music played by their teenagers and vice versa.

In addition, when your relatives come over for the weekend, they do not have to hear your private discussions with your partner or spouse. 

Also, if you have people who wake up early to go to work or school, you  are much less likely to hear alarm clocks and running showers meaning less noise for everyone in the household.

Reduction of Cooling and Heating Costs

Due to the way sound proof insulation is installed and its composition, it will go a long way in blocking those little crannies and nooks that allow air inside your house. 

A tighter home will mean that whatever happens inside the house will require less energy and within no time, you will have recouped your insulation costs by the difference you will see in your utility bills.

A Great Home Investment

Between the engendered privacy and utility savings, sound proof insulation is likely to enhance your home’s value. If you ever decide to sell your property, you will definitely be glad that you took the time to invest in it.

Sound Deadening Foam and Proofing

Noise from inside and outside the office or home may disrupt a person’s rest or work. Sound may travel through the air and still may be transmitted to pass through the walls in form of vibrations. A loud noise may even affect the health of a person.

  • Can be used in music studios
  • Can be used in computer cases

Sound deadening foam can be used in many ways.

Sound deadening foam can be used in many ways. It is mostly used in music studios in order to soundproof the whole studio so as to minimize the noise. 

It is also used by most of the bands so as to soundproof their practice rooms since the people from around may get angry with the noise. 

Another use of this kind of foam is in the computer cases. The higher end computers produces much noise in their fans and the sound deadening foam  may be used to tone down this noise.

Acoustic Foam Insulation

Foam insulation is an effective and cheap method to soundproof your room. Most of the  acoustic foam  insulation is purchased in panels and rolls. 

The foam may also act as a thermal insulation for a room. The installation of the foam has been designed in such a way that it is easy and simple but you should read the instructions carefully before doing the job.

Acoustical Drywall and Drywall Layering

This involves adding many layers of drywall in order to assist to soundproof a building. If the materials that have been used to build the walls are heavier and thicker, then it will be hard for the sound waves to penetrate through. The multiple layers of the drywall will help to block the path of the sound wave entering a building. 

Acoustic Bat Insulation

This one comes in varying thickness and density. They may be made of natural fibers or  synthetic materials . Others are made by use of the recycled materials. This method is a bit expensive than most of the others methods.

Sound Boards

They are made of compressed wood. They have a damping cover for sound if placed between the studs of wall and drywall. The drywall may help in blocking most sounds while sound board traps all noise that has high frequencies.
