Easy to adhere to pocket doors?

Asked by buildingnovice July 6, 2014

Answers

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.

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?

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.

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.

Any tips for using this on a noisy dishwasher?

Asked by steveo January 10, 2015
4
Answers

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.

How pliable is this material.. ie. is it more rubber like or stiff like tar paper?

Asked by Dola July 25, 2015

Answers

The material is about an 1/8 inch thick and very solid. It does not tear. I would say it is more like rubber than tar paper! That being said, it does not stretch. It will bend around corners, but will not stay put without staples. It is easy to cut with a razor knife.

Vapor barrier?

Asked by doofus August 21, 2015

Answers

This is actually the application that gave birth to this product one Monday after a Superbowl Sunday party and a high traffic noisy bathroom. The product acts as a moisture barrier, vapor barrier and sound barrier. The perm rating is just at .374, a class II barrier. There are no organics within the product. Mold will not grow on the product. ASTM G21-96 test yield 0 on all products. Test data confirming this may be found at http://www.dbsoundcontrol.com/testing.

Can I install this to cover my current popcorn ceiling?

Asked by rx74ray October 28, 2014

Answers

I can't see it working for your needs at all. Its to heavy to place overhead and it is to flexable. A skim coat of spackle (mud) would be a better way to go. Don't even try to use it for your appllication! This is a sound deadening material only.

Is sound proof uni-directional or bi-directional? e.g, to reduce noise from laundry room, do I have to install in Laundry room?

Asked by funfordiy November 18, 2014

Answers

Fronm my experience with this product I would say it can keep the noise out from both sides. The way you want to install is very feasible. The material could be stapled to the studs and drywall placed over it to help reduce transmission thru the studs also. I can't tell you about which way to face it but I feel it won't really matter. I just know it will really help!

Can it be used on a boat

You can use adhesive or staple it in place (the type of stapler used to put insulation in place) It does not have a sticky back.

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.

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

Like other reviews said, it's basically automobile sound deadener. Pretty heavy material. Box says it eliminates up to 75% of sound... I would say more like 30-50% in my application. I used it in an odd application. My walls are extremely soundproof, but my door is basically honeycomb cardboard. Attached with a few tiny nails. It's definitely effective but seems like higher frequencies make it through.

We use this product for cars to kill road noise and to help with the sound quality of the sound systems. 1st we add a sound deadner to the doors, 2nd we add the DB3 to the top of that and then place the door panels back on. This stuff is heavy and helps alot with keeping sounds in and keeping sounds out. We used 2 sided Velcro to hold it in place until the panels go back on.

The acoustical barrier was thicker and heaver than I expected. It appears to be very similar to acoustical shielding used the automotive world. I installed as part of a layered wall system per industry recommendations. 5/8 Drywall, R13 Batt insulation, 5/8 Drywall, Acoustical Barrier, and 1/4 drywall. I used the barrier in 1 conference room and there is a noticeable difference. It does not block 100% of the sound, but it makes the conference room more pleasant to work it.

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.

Major attenuation under drywall
Great for soundproofing a wall between kid bedrooms. Insulation between studs plus drywall, plus this stapled to first sheet of drywall, plus a second sheet of drywall. 3-year old isn't woken up by the infant screaming in the next room.

Vallyguy,

We are very happy to hear your experience. Yes, everyone, sound is very much like water, it will find a way to pass around your barrier, you must make sure you address all avenues for sound transmission with proper installation.

I am glad our product solved your solution Thank you very much for your comments.
