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.

Common Questions (5)

  • It can reduce trunk rattle and exhaust drone, especially on the trunk floor and spare-tire area. It is better at high-frequency noise and general panel damping than at low-frequency subwoofer vibration.

  • The pack provides 10 square feet total, which is enough for many smaller jobs like a trunk, cabinet, or a few NAS panels. It is less economical per square foot than larger 36-sq-ft packs, but the smaller amount can still be a good buy if you only need limited coverage.

  • It is not a good choice for a permanent door install, and it will not do much for subwoofer vibration. It works better for sealing gaps and damping thinner panels, while door seals or thicker rubber materials are better for low-frequency problems.

  • It can smell initially, but the odor may fade over time and some installs report no noticeable smell in the trunk. Using it inside enclosed areas can raise drive temperatures, so it is better suited to exterior panel damping than heat-sensitive internal installs.

    dubmangdubmangYuragk

  • Installation is labor-intensive, and prep matters as much as the install itself. Clean the surface well, apply it evenly, then use a roller or firm pressure to remove air and improve adhesion.

what's the deal here ?
It more expensive per sqft vs buying either 36sqft packs but 10sqft is enough for many use cases so it is a nice price for the smaller amount.

AI says I need 50 square feet to cover the wheel wells of a Pacifica minivan. Maybe there are larger sheets that would be more economical? FYI there is 10 square feet in this, and thickness is said to be 2mm. Seems quite thin, but the reviews are good.

I used a pack of these on an IKEA Trotten (metal storage cabinet) and it makes it sounds so much nicer/quieter. It's also the stand for my 3D printers, so it not being an empty metal shell is a HUGE benefit. It would be a massive noise maker without the pads.
(Nothing special about these specific pads, other than getting a small pack fit relatively cheap per ft)
