Our take on the TroyStudio Sound Proof PEF Closed Cell Foam with Aluminum Foil, Self-Adhesive 13" x 78" Heat Shield White Foam Sheet - Waterproof Noise Vibration Thermal Insulation Roll for Home, HVAC and Car

This is a 13" x 78" roll of closed-cell polyethylene foam with an aluminum foil face and a self-adhesive backing. It is sold as a combined heat shield, vibration damper and light sound barrier, rated at 22.1 dB noise reduction and 0.4 inch thick, covering about 7 square feet. It is waterproof and rated from -50°C to 120°C, so it suits engine bays, HVAC ducts and interior panels. At $29.99 at Amazon as of November 4, 2026, it is the only new listing, so there is no recent price range to compare against.

Questions and answers

Is this worth it for car sound deadening?
It helps with rattles, road noise and heat, but 0.4 inch closed-cell foam is a light barrier. For deep bass and loud exhausts, a butyl mat plus a mass-loaded vinyl layer does more. Use this for doors, floors and firewalls where space is tight.
How much area does one roll cover?
One roll is 13 inches by 78 inches, about 7.04 square feet. A single car door typically takes 3 to 5 square feet, so plan on several rolls for a whole vehicle.
Can it go under the hood or near the engine?
Yes. The foil face reflects radiant heat and the foam is rated to 120°C. Keep it off direct exhaust surfaces and away from moving parts, and clean the panel before sticking it down.
Does it actually block noise?
The listing rates it at 22.1 dB noise reduction, which is a lab figure, not a guarantee in a car. Expect a noticeable reduction in rattles and mid-frequency noise rather than silence.
Will the adhesive hold on a vertical surface?
It sticks well to clean, dry, flat metal and plastic. On dusty, oily or curved surfaces it can peel, so degrease first and press it down firmly or add contact adhesive at the edges.
Is it waterproof and safe in damp areas?
Yes. The closed-cell PE foam does not absorb water, so it suits ducts, wheel wells and other damp spots. Seal cut edges where moisture could get behind the foil.
