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: mnh10
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 69.
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 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 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 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 dB-3 Sound Control We have been using db3 instead of the gypsum sound control products on the market for the past 6 months. This product installs easily between the studs and drywall. We have found that it is less expensive than other products and works extremely well. Our homeowners have been very pleased with the way we have eliminated the sound transmission form home theaters and laundry rooms..

Rated 5 out of 5 by from great product Put this on the wall between my kitchen and bedroom. The difference is very noticeable. Used to be able to hear a pin drop. Now you can barely hear a cabinet door slammed.

Rated 5 out of 5 by from Amazing product almost too good to be true I'll admit it, I'm pretty sensitive to noise. I recently bought a 1920s home on a relatively busy street and some nights I feel like I'm on the Indy 500 racetrack. Many of the solutions I looked at required tearing down walls and massive construction costs- basically rebuilding, not an option for me. Someone mentioned they'd used this as wallpaper, it's relatively thick so I don't know if I'd try that in a living area. Even painted I think it would look wonky. I used this to line the insides of my closets and to line the floorboards under my house. I also used it in a studio I built outside. My contractor installed this on an interior bathroom wall and you CANT HEAR A THING. It's unreal. Caveat: This stuff is HEAVY and dense (which is probably why it's so effective at blocking noise.)

Rated 2 out of 5 by from Not so great in car After reading other reviews that said this product worked well to dampen noise in their cars, I thought I'd give it a try. So, after taking out the interior, put vibration dampener sticky mat down, a couple layers of closed cell foam, and covering most of the interior surface with this product, the cabin noise is reduced. Is it reduced enough to make me think it was worth it? No! Can I have a conversation without having to raise my voice? No. Do I still have to crank up the stereo just to hear it? Yes. I don't know how well it works behind drywall, but for cars I would look elsewhere. For what it's worth, I've found that just putting fiberglass insulation behind drywall walls does a pretty good job of reducing noise.
