Rated 5.0 out of 5.0 by tom 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 1.0 out of 5.0 by master 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 5.0 out of 5.0 by FireFighter 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 5.0 out of 5.0 by Caroline 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 1.0 out of 5.0 by Daniel123 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.

Rated 5.0 out of 5.0 by beeman 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.
