Our take on the Reflectix Insulation Self-Adhesive Moisture-Resistant Reflective Insulation Foil

This is a 1 x 5 m roll of double-sided aluminum foil insulation bonded to a polyethylene core. Reflectix-style foil reflects up to 97% of radiant heat, resists moisture and corrosion, and is sold as a wrap for radiators, walls, roofs, floors, garages and sheds. The best new price is $67.00 at Amazon as of November 4, 2026, and only one store lists it new, so there is no cheaper new option to compare against.

Questions and answers

Is Reflectix foil insulation worth it?
It is worth it for blocking radiant heat, such as behind a radiator or under a roof, where an air gap exists. It will not replace fiberglass or foam board for conductive heat loss.
Does it really reflect 97% of heat?
The foil surface reflects up to 97% of radiant heat when clean and facing an air space. Performance drops sharply if it is pressed flat against a wall or covered with dust.
How much does the 1 x 5 m roll cover?
The roll covers 5 square meters, about 54 square feet, in a 1 m wide strip. Measure your radiator or wall area before ordering, since one roll goes quickly on larger jobs.
Can it be used outdoors or in a damp cellar?
Yes. The foil is waterproof and corrosion resistant, so it suits cellars, sheds and camper walls. Seal the edges to keep moisture from getting behind it.
Is it fire resistant?
The aluminum foil outer layers resist fire, but the polyethylene core is combustible. Keep it away from open flames and check local code before using it around stoves or flues.
When is the price lowest?
Only one store, Amazon, lists it new at $67.00 as of November 4, 2026, so there is little room to shop around. Watch for roll-size discounts rather than store-to-store price gaps.
Where is the Reflectix Insulation Self-Adhesive Moisture-Resistant Reflective Insulation Foil cheapest?
At Amazon, for $67.00, as of our latest check.
Where can I buy the Reflectix Insulation Self-Adhesive Moisture-Resistant Reflective Insulation Foil?
