Our take on the Universal Automotive Sound Deadening Mat and Heat Thermal Insulation Foam Roll, 19.7 x 78.7 in

This is a cut-to-fit roll of closed-cell foam faced with aluminum foil, sold for damping noise and blocking heat in cars. The foil layer reflects radiant heat, while the foam absorbs some road and engine sound. It is a budget, general-purpose material rather than a branded butyl mat, so it works best as a supplement to a proper vibration damper on floors, doors, firewalls and trunks. Expect modest gains in a quiet cabin, not a luxury-car transformation.

Best forDIY owners adding cheap noise and heat controlFirewall, floor and tunnel heat shieldingTrunk and door panel lining on a budgetOlder cars with thin factory insulation
Pros
  • Foil face reflects radiant heat from engine, exhaust and sun
  • Lightweight foam is easy to cut and shape around contours
  • One large roll covers floors, doors or a trunk
  • Works on flat and curved panels without special tools
  • Cheap way to test whether extra insulation helps your car
Cons
  • Foam alone does little for panel vibration; needs a butyl or CLD layer underneath
  • Adhesive backing is often weak and needs extra spray glue
  • Thin material, so expect only moderate noise reduction
  • Foil can tear and edges fray during fitting
  • Not fire-rated for use near hot exhaust or engine surfaces

Questions and answers

Does this replace a butyl sound deadening mat?
No. Foam absorbs sound and blocks heat, but it does not stop panel vibration. Use a butyl or constrained-layer mat on the metal first, then this foam on top.
Can I use it on doors and the roof?
Yes, but the adhesive is often weak on vertical and overhead surfaces. Add a spray adhesive and press it firmly.
Is it safe near the engine or exhaust?
Keep it off hot exhaust parts and check the material's temperature rating. Foil-faced foam is meant for firewalls and floors, not direct contact with hot metal.
How much area does the roll cover?
The roll measures 19.7 by 78.7 inches, about 10.8 square feet. That is enough for a trunk floor or a couple of doors, not a whole car.
Will it make my car much quieter?
Expect a modest reduction in road and engine noise. Most of the gain comes from combining it with vibration damping and sealing gaps.
