Quiet Barrier™ MD Soundproofing Composites (1/8 in. 1 lb. barrier + 1 in. foam) are industrial grade products that stop sound from entering or leaving a space. These products are composed of Quiet Barrier™ soundproofing membrane and acoustic grade, polyurethane foam. The Quiet Barrier™ provides mass and blocks noise, while the acoustic foam works as a decoupler, structurally isolating the Quiet Barrier™ layer from the wall or ceiling assembly, which in turn improves the sound stopping performance.

Features / Benefits
Triple soundproofing function — The mass of Quiet Barrier™ blocks sound while its flexible nature dampens sound energy. The Acoustic foam acts as a decoupler, structurally isolating the heavy barrier layer from the construction assembly, ultimately increasing the sound blocking performance.
Low Profile — Quiet Barrier™ soundproofing composites range in thickness from 9/16 inch to 1 ¼ inch, saving valuable square footage.
Variety — Quiet Barrier™ soundproofing composites are available in a variety of weights and thicknesses. Quiet Barrier™ soundproofing composites are available with an optional “peel and stick” pressure sensitive adhesive (PSA).
In-stock — We stock all advertised sizes and configurations of Quiet Barrier™ soundproofing composites. Most products are shipped the same day they are ordered and arrive at your project in three business days.
Proven History — Over 1 Million square feet of Quiet Barrier™ soundproofing composites are installed in projects nationwide.
Flammability — Quiet Barrier™ Soundproofing Composites contain polyurethane foam that has a flammability rating of UL94 HF-1. Before choosing this product, be sure the flammability rating passes your local building code for exposed materials.

Which Quiet Barrier™ Soundproofing Composite is right for me?
Quiet Barrier™ Soundproofing Composites can be added to a variety of existing wall constructions to improve the sound blocking performance of the structure. Choose the right Quiet Barrier™ Soundproofing Composite based on the type of noise you are trying to prevent from entering or leaving the space. As a rule, the thicker and heavier the Quiet Barrier™ Composite, the better it will be at reducing sound transfer. The thinner Quiet Barrier™ Composite products perform well when trying to deter common noises with average decibel levels. The thicker Quiet Barrier™ Composite products perform well when trying to deter common noises with high decibel levels. In essence, the louder the sound you are trying to stop, the thicker the product needs to be. First determine how much sound you need to stop, and then choose the appropriate product.
How Quiet Barrier™ Soundproofing Composites work
In essence, Quiet Barrier™ Soundproofing Composite products block the transmission of noise from one area to the next. The “noise source” hits the barrier and is reflected back into the room or space of origin. See figure 1. Typically, the noise is not muffled or absorbed in any way, which means that decibel level within the source room remains the same or is increased. The difference between the source noise and the transmitted noise is the sound transmission loss.
Polyurethane Foam Warning
All Polyurethane Foams, including Combustion Modified Foams, will burn. Do not expose to any flame source. Once ignited, they can produce rapid flame spread, intense heat, dense smoke and toxic gases causing death. Warnings should be given to your employees and or customers. Test data does not necessarily reflect a foams performance under actual fire conditions. Before purchasing any foam, be sure to check with your local code officials to confirm the required flammability rating of exposed materials for your area.
Cautions and Limitations
- Before applying this product all surfaces must be dry and clean, free of any grease or oil.
