Works well to dampen noise from a 4" sewage drain pipe.

We had to take our place down to the studs so we the opportunity to try to soundproof our mother in law rental unit from the main house. We put this in place over what were once doorways between the two units. We put it over the insulation under the drywall. We used the green tacks you can buy here on Amazon to put in place. We then used green goo sealant on the drywall. It absolutely shut down the sound, which has been an issue in the past. Its heavy but very easy to cut to size with scissors or a utility knife. We are also using in a bathroom adjacent to the other unit which has sound issues. It might seem expensive but it's actually a very cost effective way to soundproof or drastically cut sound. We used Rockwool Safe and Sound insulation, another great product for reducing sound in a home or office. You can get the insulation at Home Depot or Lowe's.

Me funcionó excelente para insonorizar un tubo de PVC que tenía mucho ruido de agua y vibraciones. Enrollé la barrera de vinilo con masa alrededor del tubo y lo fijé bien.

It is a bit early to find out if it does what it is meant to do, but I can say now that is that I am going to need quite a lot more for my requirements. I should have checked the measurements of the product more carefully! It is going to cost me a lot of money. I am going to look for substitutes as I won't be able to afford more of this.

We bought a new-to-us house that was built in the 80's and one of the things we noticed during our initial inspection was the tremendous amount of noise and sound coming from the drain fall pipe that runs through the dining room wall from the 2nd floor bathroom. I'm a contractor and was already planning tearing open the drywall to remove a load bearing wall, so I planned on tackling the noise issue at the time. I used this along with closed cell foam to soundproof a drain fall pipe running through the dining room ceiling and wall from second floor bathroom to basement. Wrapped the fall pipe, added some addition acoustic batt and vapour barrier in ceiling joist cavity, and closed up the drywall. It's now absolutely silent - completely solved the problem. Great stuff
