Customer Questions & Answers

Can unfinished wood plank flooring be installed by nailing through sound board to subfloor beneath?

I want to install hardwood flooring in my condo and have been told it has to be a floating floor, rather than nailed down because of the sound boards.

is this product paintable?

is this product paintable?
Asked by: yu
It is paintable ( any latex) If you do that, the paint will form a skin & any thumbtacks will show the holes through the skin. The product is not smooth like drywall. I have stained it in the past with interesting results. Hope that helps, Tom

How much does one sheet cost?

Asked by: dave
Eastern PA it sells for around .90 per SF, much cheaper than Quietrock. Use it & a regular sheet of drywall, I get same results for 1/2 the price.

What does 440 stand for is that the noise reduction number if not what would be the noise reduction number be

Asked by: Rob
I think it has to do with the density of the board. Noise reduction is measured in a wall by STC points. Website shows a reduction of 14-15 points when installed correctly. Great for bathroom common walls, home theaters, bedrooms. Good luck, Tom

Sound Barrier Sheathing 1/2 in. x 4 ft. x 8 ft. R-1.2 Sound Board is rated 3.7 out of 5 by 6.
Rated 5 out of 5 by from Great for Stained Glass I use this as an assembly board when creating Stained Glass panels. It is easy to cut to a more manageable size. it is also extremely fire resistant which is crucial when soldering with hot lead. I have even used an old piece on my lawn to protect it when setting off fireworks

Rated 5 out of 5 by from Used this in a home theater Followed installation instructions from website. It worked great in wall applications, attached drywall right to it, no issues. A product that was easy to cut and worked as advertised, would buy it again!

Rated 5 out of 5 by from Product works GREAT I used this 440 soundbarrier on a floor project and it works GREAT. I have a room with a high amount of foot traffic on the second floor with offices below it. You could hear everything before I installed the soundbarrier. I spoke with the Technical support desk and he gave me valuable information in regards to how the product works as well as how to install it correctly. I will definitely use this product again.

Rated 1 out of 5 by from waste of money, time and effort Don’t buy this product! It just waste of money, effort and time. Nothing else. Firstly, at approximately $29.00 per sheet this material not even uniform in thickness. It wary from 3/8” to 5/8”, but that is minor problem. Forget the soundproofing ratios. It simply not there. No soundproofing whatsoever. Airborne sound nor impact noise. NOTHING AT ALL. 3/8” plywood probably would do a better soundproofing job. Tried this 1/2" homasote on two floor projects in my duplex. It feels like it is not there. It is not a soundproofing board, it is a bogus.

Rated 5 out of 5 by from Works great I was told to use this for my Bee Hives for Winter moisture control. It works great, bees are able to get to the trapped moisture and use it to dissolve honey stores in winter months. It also kept the hive warmer than just the wood top.

Rated 1 out of 5 by from Run dont walk I bought this board for ceiling sound insulation. My neighbor upstairs has very heavy feet, I can hear every step. After attaching 440 sound board and covering it with drywall, absolutely nothing has changed. I can still hear all the steps and talking/music. WAIST of $200. DO not buy this product. It's absolutely worthless.
