Our take on the 4X50 Aluminum Foam Neoprene Sheet Self-Adhesive Backed Reflective Insulation 5MM

This is a 5mm closed-cell XPE foam sheet faced with reflective aluminum and backed with self-adhesive glue, sold as a 4 ft by 50 ft roll. It is meant for sound deadening and heat reflection in cars, vans, trucks and RVs, and it can also line attics, sheds and metal panels. Against butyl mats it is far lighter and easier to cut, but it damps vibration less and has no mass layer. Against thin foil bubble wrap it blocks radiant heat similarly while adding a foam layer that softens panel resonance and road noise.

Best forCar, van and RV owners cutting road and panel noiseDIY attic and metal building radiant barrier projectsCovering large flat surfaces on a budgetBuyers who want peel-and-stick installation without glue
Pros
  • Closed-cell foam resists moisture and won't soak up water
  • Reflective aluminum face blocks radiant heat
  • Self-adhesive backing speeds installation
  • Light and easy to cut with scissors or a knife
  • Large roll covers a lot of surface in one piece
Cons
  • 5mm foam alone damps vibration less than butyl mats
  • Adhesive can lift in high heat or on dirty, curved surfaces
  • Foil face dents and tears if handled roughly
  • Little official fire or R-value rating for building use

Questions and answers

Will this actually quiet a car or van?
It reduces road and panel noise somewhat by absorbing sound and stopping resonance, but 5mm foam is not a full sound-deadening solution. For engine, exhaust or heavy bass, pair it with a butyl mat on the largest flat panels.
Can I use it in an attic or on ductwork?
The reflective face works as a radiant barrier on attic rafters, metal roofs and ducts. Keep it off hot surfaces and check local code, since the foam has no published fire rating.
How well does the adhesive hold?
It sticks well to clean, dry, flat metal and plastic. On dusty, oily or sharply curved surfaces, or in very hot areas, clean first and add mechanical fasteners or tape at the edges.
Does it handle moisture?
Yes. The closed-cell XPE foam does not absorb water, so it suits doors, floors and wheel wells where damp is a concern.
What thickness is it?
The foam is 5mm, about 1/4 inch, with the aluminum facing and glue on top of that. It is thin enough to fit behind door panels and under carpet.
What comes in the roll?
One 4 ft by 50 ft roll of aluminum-faced, self-adhesive foam. You cut it to size yourself.
