Wall Soundproofing

Reduce Noise From Coming Through Your Walls

Sound transmission through walls – We use combinations of sound barrier and sound absorption materials, combined with customized construction techniques, specific to your indoor noise problems to reduce the sound transmission through exterior or interior walls.  Our Sonic-Shield acoustic barrier materials, when added to a typical wall, can increase the STC of the wall from 33 to over 53, reducing the perceived loudness of the transmitted noise by 75%!

Acoustical Treatments Made In The U.S.A

Sound from adjacent rooms or hallways can pass through walls and disturb you. Typical noise sources include loud talking, wall mounted television sets, audio equipment, alarm clocks, and noisy plumbing. 

Indoor noise may most commonly be thought of at home or the office, but how about other areas at the workplace? A production floor, a warehouse, a storage room,  or really any place machinery is located. At Sonic-Shield, we use both sound barrier and sound absorption materials to dampen or completely deaden indoor noise from a variety of sources in the home and office. However, we also use sound dampening enclosures, acoustic panels, curtains, baffles, blankets and a wide variety of other solutions to address your specific indoor noise problem. 

Soundproofing Solution: For new construction of walls, floors and ceilings, we recommend combinations of Sonic-Shield sound barrier material in conjunction with underlayments, absorbent products and the necessary accessories to help break the connections that move vibrations (and the noise they create) through the structure.  For existing structures, our Sonic-Shield barrier materials, when added to a typical wall, can increase the STC of the wall from 33 to over 53, reducing the perceived loudness of the transmitted noise by 75%. Every situation is unique and requires a customized solution to meet the property’s individual needs.

Specifically for wall soundproofing we suggest adding a combinations of the following:

Quiet Insul: The best acoustical insulation in the industry! This is a cotton based insulation that has a high absorption value along with a Class A fire rating. Just like regular insulation, this goes between the studs of the wall and will absorb the noise that enters the wall. Absorbing the noise will lessen the noise pressure, reducing any noise from coming through. 

Sonic-Shield Acoustic Barrier: Also known as Sound Barrier MLV - this high dense material comes in 1-lb/sf and 2-lb/sf which is 1/8" and 1/4" respectively in thickness. This thin material is very heavy and dense to block the airborne noise from coming through. This material gets mounted on the studs and sealed up completely with our MLV Tape. This material can easily get nailed to the studs to allow for a quick easy install!

Sound Isolation Clips System: This additional feature that can be added to the above materials is to help with low frequency noise. Usually vibration through walls isn't a major issue, but sometimes it is. When someone has a loud stereo, TV mounted to the wall, bad footfall noise, and even dogs barking or cars driving by, then they want to use the Sound Isolation Clip System. Mounting our Isolation clips to the studs in a staggered pattern, then mounting hat channels to the clips, will isolation the vibration that comes through the wall. Sheetrock will then be mounted to the channels so when the wall vibrates, the sheetrock won't!

Accessories: Along with the above products, accessories like Sound Putty Pads, MLV Tape, and Acoustical Sealant is needed to finish off the wall.

The Sound Putty Pads are used to protect any outlets, light switches, and anything else that is penetrating the wall. The pads get wrapped around any electrical box that is used in the wall, sealing off the box. We always suggest putting low voltage into a electrical box as well to properly seal that box. Sealing with the Sound Putty Pad will increase the sound blocking of the boxes, minimizing leakage. 

MVL Tape is used with the Sound Barrier both 1LB and 2LB product. It is made of the same material as the barrier but with a pressure sensitive adhesive on the back, making it a great tape to use. Use it on the seams of the barrier to seal it up completely. 

Acoustical Sealant is used around the perimeter of the sheetrock. Remember when you sheetrock (or blue-board) the wall, to keep a 1/8" or so gap around the perimeter and fill it with the acoustical sealant. The reduces the vibration from the other walls to come into the wall you worked on. 

Extra Add On - Green Glue Compound: Adding a extra layer of sheetrock or blue-board will increase the sound reduction, but when you do that you must add in our Green Glue Compound to that extra layer to ensure the best soundproofing. This is a easy step that is easy and fast to do. Prior of mounting the second layer, you will add 1.5 to 2 tubes of Green Glue compound to the sheet and then install that second sheet as normal. This significantly increases the STC and blocks the noise!
