Questions & Answers

Easy to adhere to pocket doors?

Took down too-noisy pocket doors thinking to buy foam filled doors -- NOT available. What to do? Will this adhere to old flat doors and can it be painted. What elce can I do? Can I find foam filled doors?
Asked by: buildingnovice
Putting foam in the doors will do almost no good. It will increase STC of the door by less that 3 dB at mid-range to low frequencies. Sealing the perimeter of the door with weather stripping (the denser the better) will have a much greater effect.

Any tips for using this on a noisy dishwasher?

I expect to use either glue or possibly double sided tape to adhere the barrier to the sides, top and back of the dishwasher. If I have enough, I will also try to put some underneath the dishwasher. I expect to seal all seams with duct tape. The dishwasher is located in a central island on our main floor, basement underneath. Any tips??
Asked by: steveo
yes, recommend to apply it directly to the dishwasher unit itself, underneath the factory installed fiberglass insulation blanket, which usually covers the top and two sides of the appliance, sometimes the rear as well. This will more than double the sound deadening of the existing insulation when you replace the blanket, AND apply the 3M barrier to the inside walls of the kitchen cabinet housing the dishwasher. Apply to the FLOOR underneath the DW, the side walls, and underside of the countertop above the DW for best results.

I would like to reduce the sound coming from a refrigerator that is set into a 3 sided recess. Is this the appropriate material to put on the walls?

Asked by: mnh
Do you mean the noise is reflecting back into the room from the refigerator? I know it will stop noise from coming thru the sound deadening material but I don't know about stopping noise being reflected back into a room. Sounds like you might need an accoustic material (like ceiling panels with sound trapping holes in it).

Can I affix this to the framing of an interior French door? I want to deaden the sound between my office the person on the other side of the doors.

Asked by: CyberBeth
Yes. I used on my basement door to stop well pump noise from coming into the living area and it does work. Remember it does have a look like a sheet of rubber but it can be cut and painted.

4 ft. x 8 ft. Acoustical Barrier is rated 4.2 out of 5 by 71.
Rated 4 out of 5 by from Got Noise? Not anymore! I used this DB-3 Barrier on top of an existing wall built in the 1950's. I used a green product adhesive of choice and applied it to the wall and layed the barrier over it and used a few nails to hold in place. I waited a day and then applied the Soundproofing drywall named "quietrock" over this. The outcome was jaw-dropping. At three in the morning while playing music or talking on the phone there is no (Nada) noise even with my ear pressed against the wall. Highly recommend this product for use. Just a little research and some comon sense techniques and you have the solution. Like they say "You can do it, we can help"! Victor Ramirez

Rated 5 out of 5 by from Very Satisfied with this Product dB-3 for Walls We needed a sound barrier to reduce the noise from our In-Law Quarters & the Main House and this product did exactly as it said it would. We didn't need to do a full wall, but over section of wall where we had French Doors with sidelights. Definitely made a difference in sound control. (Those darn 30-something kids of ours & their music--LOL) It IS a bit pricey, so I was glad we weren't doing a full wall. Installation was very easy. And, as someone else mentioned, it's too bad this product is not carried IN the store where it can be purchased directly instead of online--even though we received it VERY quickly from manufacturer. Very Happy with this purchase.

Rated 5 out of 5 by from Privacy achieved We bought a new home that unfortunately has a bathroom that shares an uninsulated wall with the family room. While watching tv, or visiting with family and friends, we had a lot of "I know what you're doing" moments. Insulating the wall was a "must" but the idea of tearing down drywall and replacing it just to install insulation was not a feasible option. We installed the acoustical barrier in the bathroom with a staple gun and painted over it. The difference was like night and day. With the bathroom door closed, privacy has been achieved!

Rated 4 out of 5 by from Should work well Feels like a very thick non-marking tar paper. The cushioning effect is just about right to quiet sound coupling. I also placed unfaced fiberglass insulation in the wall and the combination seems to be working. The con, the roll is 8 feet long and meant to drape vertically on the wall. The roll is heavy and I could not hold the top evenly at the ceiling while getting enough staples in it so they did not tear out. It requires a two person installation. If the roll had a stronger top lip so that one staple could temporarily hold it up, then it could possibly be installed by one person.

Rated 5 out of 5 by from Does what it says for a great price. I put this up in my home theater room and laundry room. We moved from a very similar style home with metal studs and thin drywall. The sound that escaped both rooms was an annoyance! This product almost eliminated sound coming from the theater and totally knocked out the sound from the laundry room. The only thing that escapes is the loudest parts of a movie with huge bass like the T-Rex from Jurassic Park or other massive explosions from video games. We like our movies/games loud at our house and we don't want anyone outside the room to know about it or be bothered by it. My HOA is pretty overbearing.... I would confidently advise using this if you have any sound issues in home or office.

Rated 4 out of 5 by from A Lightweight Mass Loaded Vinyl DB-3 Acoustical Barrier is essentially a lightweight mass loaded vinyl (3/4 lb/sq.ft. vs standard 1 lb/sq.ft.) Included leaflet cites STC "maximum" rating of 73, which is, realistically speaking, is way, way overstated. My lazy method of simply nailing sheets to the wall, taping seams and covering it all with wallpaper reduced noise level somewhat, but not by much. Still, I'm satisfied with result. United Plastics installation video makes it seem like installation is effortless. It is not. Unless you are well practiced at handiwork and weightlifting, it's hard to properly keep the roll in place with one hand. The price of this insulation is perhaps the lowest you can find, and quality seems to be good.

Rated 5 out of 5 by from Cheap MLV This product is basically cheap Mass Loaded Vinyl (MLV). It is 4x8=32 sqft. It weighs 32 lbs, making it 1 lbs per sqft. It costs under 30 dollars and ships for free if you buy 2 or more. This makes it the holy grail, 1 lb MLV for under a buck. It is not as flexible as I believe some MLV might be, so it might not be practical in certain automotive applications that require tight curves. However for anything where you need flat, thin, heavy material for sound insulation, this is the cheapest option.

Rated 5 out of 5 by from car audio applications on doors and floor I am an acoustical engineer who designs commercial buildings. We use MLV for noise abatement in walls on occasion. For walls, you're better off with Green Glue between two layers of GWB. The mobile audio community also wants MLV for road noise abatement in cars. This product works great on both vehicle doors and floors - but does require a decoupling layer. CCF can be used but I prefer a radiant/acoustical barrier using ultratouch insulation (also sold by Home Depot). This product is closer to .75lb/sq.ft. so the transmission loss is less than 1lb/sq.ft. products. However, due to contribution of flanking paths, this product will perform as well in most applications. Proper fasteners and decoupling are recommended.
