Our take on the Wall Thermal Insulation Reflective Aluminum Foil Film 10M

This is a 30cm-wide, 10m-long roll of reflective aluminum foil laminated to 3mm polyethylene foam. It is meant to be cut and mounted behind a radiator or on a wall to bounce radiant heat back into the room instead of letting it soak into the wall. It is a simple, low-cost retrofit for renters and owners with older radiators, and it does one job: reflect radiant heat. It does not add insulation value like rigid foam board or mineral wool, and it needs tape or adhesive you supply yourself.

Best forRenters with older panel radiators on exterior wallsCheap, quick heat-loss fix behind radiatorsDIY insulation of containers and small spacesPeople who want a cut-to-size roll, not a rigid panel
Pros
  • Reflects up to 90% of radiant heat, per the maker
  • 3mm foam backing adds a thin layer of insulation
  • Cut-to-size roll fits most radiator widths
  • Works on walls, radiators and containers
  • Light and easy to handle
Cons
  • Tape and adhesive are not included
  • Only 30cm wide, so wide radiators need seams
  • Thin 3mm foam adds little conductive insulation
  • No fixings or instructions beyond cutting to size
  • Foil surface can tear if handled roughly

About the Wall Thermal Insulation Reflective Aluminum Foil Film 10M

This is a reflective thermal insulation film made of aluminum foil laminated to a foam polyethylene (pearl cotton) layer. It is 3 mm (0.12 in) thick and comes as a roll.

Placed behind a radiator, the film reflects up to 90% of the radiant heat back toward the room instead of letting it into the wall. It fits any radiator model and can also insulate various containers.

To install, cut the film to the size of the radiator. Attach it with a special adhesive or with double-sided tape. Neither the tape nor the adhesive is included.

Questions and answers

Does it actually lower heating bills?
It reflects radiant heat back into the room, which can help a radiator mounted on an exterior wall. The effect is modest and depends on your wall and radiator type. It is not a substitute for proper wall insulation.
How do I attach it to the wall?
The roll ships without tape or adhesive. Most people use double-sided tape or a spray adhesive on the foam side, cut to the radiator's size first. Foil facing the radiator is the usual orientation.
How wide is the roll and will it cover my radiator?
The roll is 30cm wide and 10m long. A standard radiator is often wider than 30cm, so you will run parallel strips and seam them. The length is enough for several radiators.
Can it be used anywhere other than behind a radiator?
Yes. The maker lists containers and general wall use. It works anywhere you want to reflect radiant heat, such as behind a wood stove clearance area or around a hot water tank, as long as it is not in direct contact with a heat source hot enough to melt the foam.
Is it fire resistant?
The maker does not state a fire rating. The core is polyethylene foam, which melts and burns, so keep it off open flames and hot surfaces. Do not use it where building codes require a rated barrier.
How does it compare with foil-faced foam board?
Board is rigid, thicker and easier to mount cleanly, but costs more and is harder to cut around pipes. This roll is thinner and more flexible, better for odd shapes and tight gaps, with less insulating value.
