This is a double-sided reflective foil radiant barrier wrapped around a closed-cell foam core, sold as a 4 ft by 100 ft roll. It reflects about 97% of radiant heat and is rated ASTM Class 1 / Class A (E84 and E2599), so it can go in walls, ceilings, floors, attics and crawl spaces. It is fiber-free and non-itchy, cuts with a knife or scissors, and holds staples without tearing, which makes it easier to handle than fiberglass batts. Against bubble-foil products it is thicker and does not collapse, but it is still a radiant barrier and thin foam, not a substitute for mass insulation in a cold climate.

This is a double-sided reflective radiant barrier with a closed-cell foam core. It comes as a continuous roll measuring 4' x 100' with a 3.5MM thickness. The foam core does not compress, collapse or disintegrate, and the material is lightweight and durable enough to hold staples without tearing.
The surface reflects 97% of radiant heat and emits less than 3%. It is fiber-free, non-toxic and non-carcinogenic, so installing it does not require protective clothing or a respirator. 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.
Cut it with a utility knife or scissors. Hold it in place with staples, nails, glue or spray adhesive. It reduces the load on heating and cooling systems and also provides some soundproofing when used in walls, ceilings and floors.
