When you want silence, you wish you could shut out all outside sounds. Sometimes, however, our wish for quiet seems impossible with barking dogs, passing cars, loud conversations, and blaring music. If you’ve invested in a pair of earplugs or sound-blocking headphones, there’s a better solution.

Quiet Board™ Acoustic 2” Panels provide you with the noise reduction you need — no ear buds or cotton balls required. It’s as simple as purchasing the acoustic panel you need, applying your adhesive and waiting for the sweet sound of silence to ensue. Why make soundproofing difficult with technology this easy?

Moisture Resistance and Durability

Not only do our Quiet Board™ products deflect and absorb unwanted noise, but they also provide moisture resistance in any area they’re installed. Any area needing soundproofing and sound absorption shouldn’t have to worry about subpar performance due to inferior composition. Luckily, our 2-inch water resistant acoustic foam panel is moisture resistant, meaning you can wash and hose down your surfaces without worrying about extra water build-up or a lowered quality.

When you need a durable product, our 2-inch water-resistant acoustic panel is ready to perform. With high levels of resistance to chemicals, bacteria and fungi, the only outcome of your acoustic panel is superior performance. Simply trim your panel to the desired shape, attach it to a given surface and let Quiet Board™ Acoustic Panel take care of the rest.

Features / Benefits

Dual Purpose Acoustic Material — Quiet Board™ is truly unique in that it absorbs as well as deflects noise. The irregular surface texture absorbs 50% of airborne sound and the smooth, dense polypropylene core material deflects 50% of the sound back towards the noise source. This product is perfect for areas that need both soundproofing and sound absorption. See acoustic data below.

Value — Quiet Board™ is a perfect choice for applications that need acoustic improvement and soundproofing but where budgets are tight. When compared to other, one dimensional products, it is a great dual functioning product for a great price.

Moisture Resistant — Unlike most sound absorption products, Quiet Board™ is moisture resistant. It is also washable so it can be applied to areas that may get dirty and require an occasional hose down.

Durable — Quiet Board™ is impact resistant with good resistance to chemicals, bacteria and fungi.

Easy to Install and Handle — Quiet Board™ is light weight and can be attached to a variety of surfaces. These panels contain no fiberglass and have little to no odor. Quiet Board™ is attached to substrates with construction grade adhesives. For cutting or trimming, use a serrated knife or a circular saw with a 45+ tooth blade. Be careful!

Excellent Flammability Rating — Quiet Board™ has a Class A™ flammability rating. This product passes most building code flammability requirements for exposed materials.

Installers Should Know

Quiet Board™ is a thermal molded product and although tough to see, one side of the panel will have injection and mold release marks. The marks are circular and range in size and indent depth. These marks denote the back side of the panel, so panels should be installed with these marks facing the wall or ceiling for best possible aesthetical outcome.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend Soundproofcow.com to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
