Our take on the XTEMP 3mm Reflective Insulation roll, Foam Core Radiant BARRIER 24" X 10'

This is a 24-inch by 10-foot roll of reflective radiant barrier with a foam core, made to block radiant heat rather than slow conductive heat like fiberglass. The foil face reflects about 97% of radiant heat and the material is ASTM E84 Class A fire rated, fiber-free and safe to handle without protective gear. It suits attics, garage doors, walls, ceilings and floors where you want a thin, moisture-tolerant layer that also dampens some sound. Against fiberglass batts it is far thinner and easier to cut and staple, but it has little R-value on its own, so it works best as part of a system rather than a stand-alone insulator.

About the XTEMP 3mm Reflective Insulation roll, Foam Core Radiant BARRIER 24" X 10'

This is a 3mm foam core reflective insulation roll that works as a radiant barrier. It reflects 97% of radiant heat and emits less than 3%. It is silver and measures 24 inches by 10 feet.

The material does not compress, collapse or disintegrate. It is fiber-free, non-toxic and non-carcinogenic, so it can be handled and installed without protective clothing or respirators. It is not affected by moisture or humidity, inhibits condensation, and does not promote the growth of fungi, mold or mildew. It also does not promote nesting of insects or rodents.

It cuts with a utility knife or scissors. To install it, staple, nail or glue it, or hold it in place with a spray adhesive. By reducing stress on heating and cooling systems, it helps keep a home warmer in winter and cooler in summer. It also provides some soundproofing when used in walls, ceilings and floors.

Questions and answers

Does this replace fiberglass insulation?
No. It blocks radiant heat and adds a little conductive resistance, but its R-value is low. Use it with bulk insulation, not instead of it.
Can I install it without protective clothing?
Yes. The material is fiber-free and non-toxic, so gloves and a respirator are not required. A knife or scissors and a staple gun are enough.
Is it fire rated?
Yes. It is ASTM E84 Class A rated and described as flame retardant and non-flammable.
Will it handle a humid attic or crawlspace?
It is not affected by moisture or humidity and resists mold, mildew and condensation, which suits damp spaces better than fiberglass.
How do I fasten it?
Staple, nail, glue or spray-adhesive it in place. Seal seams with foil tape for the best radiant barrier performance.
Does it block sound?
It provides some soundproofing benefit in walls, ceilings and floors, but it is not a dedicated acoustic panel.
