I used this to cover the outside of a QNAP 4-bay NAS and now you can have it in a normal room instead of in the closet...in the basement...in the neighbor's house. You can hear the drives still if you listen for them, but sooo much quieter. Only used 3 sheets to cover all 4 sides with front and back.

It will increase temp of your drives inside and will accelerate their failure.

Do not use that Peel and Seal roofing crap for this purpose. They are NOT similar. Peel and Seal is asphalt based. This is butyl rubber. And on that note, this isn't quality CLD either. Better than nothing? Of course. But if you're serious about audio/sound isolation, use something like Resonix.

Community Reviews

This Amazon Basics sound deadening mat is a thin butyl foil sheet that works best for reducing rattles and higher frequency noise in cars, cabinets, and other metal enclosures. It can make a trunk, NAS, or metal cabinet noticeably quieter, and the 10 square feet is enough for many smaller jobs. The main tradeoffs are heavy labor to install, careful surface prep, and limited help for subwoofer vibration or permanent door installs. It is also described as less robust than premium damping products, though still useful for extra soundproofing.

Brutal amounts of labor to install

Like many things the prep work is as hard, or harder, than the install.

So yea clean any surface well, roll on even, and then press/roll it to get all the air out and pressure to it.

This is correct, the peel and seal stuff gets really stinky/smells as well.
This amazon CLD isn't great either. it's very thin and not thick quality like the competition. It will help, just not as effective.

im guessing you mean the sticky side?
i dont know, i feel like it works just fine for sealing gaps and the roll is big enough to cover large areas in the trunk.
and it doesnt smell, at least not in the trunk at all. and its held up for years.
also downside is it is heavy which sucks because racecar

i am not an audiophile but i can tell a difference. especially putting it on the trunk floor/spare tire area for exhaust drone.

NO, this is not the same as asphalt roof flashing.

Is this like a generic version of Dynamat? I remember the glory days of having that stuff in my trunk with my 2 JL Audio 12's and PPI and Soundstream amps. It definitely stopped the rattle.

Can I use it for my front door for privacy?

I noticed a lot of the inside noise (like talking, listening to music, etc) is bleeding out into the hallway (I live in an apartment complex). I was hoping to get something to help with privacy, and also prevent noise from the hallway of bleeding into the home (as my dog will sometimes start to bark, and yes we're working on him as well). I was thinking of putting it on the front door and further seal the opening around the door.

Another use is, I have a subwoofer, and I don't want it to make too much noise and bother the neighbor below. So can I use this underneath my subwoofer?
