- Will this actually block noise between rooms?
- It reduces noise rather than silencing it. The maker claims up to 22.6 dB, which is a noticeable drop but not full soundproofing; for walls you would need mass and decoupling as well.
- Can it be used in a car engine bay?
- Yes. The foam is rated to 320°F and the foil reflects radiant heat, so it suits firewalls, floors and door panels. Keep it off exhaust parts that run hotter than that.
- Does the adhesive hold on vertical surfaces?
- The self-adhesive backing bonds to clean, dry, smooth surfaces. On dusty, oily or rough surfaces, clean first and add mechanical fastening or contact adhesive for a lasting hold.
- Is it waterproof?
- The closed-cell structure does not absorb water, and the foil face sheds it, so it works in damp areas and outdoors. Seal cut edges if the foam will sit in standing water.
- How much area does one roll cover?
- One sheet is 13 x 39 inches, about 3.52 square feet. Measure your panels and plan on multiple sheets for anything larger than a small panel or a few pipe runs.
- Can I cut it to shape?
- Yes, it cuts with a sharp utility knife or scissors. Cut foil-side up and use a fresh blade, since the foil and dense foam dull blades quickly.
