This is a 24-inch by 100-foot roll of closed-cell polyethylene foam faced with reflective aluminum foil on both sides, sold as a radiant barrier and vapor barrier for walls, roofs, garages and outbuildings. The maker rates it at R-15.67, says the R-value holds up in humid conditions, and claims it blocks 97% of radiant heat transfer while adding about 19 dBA of contact noise reduction. It is thin and flexible, so it wraps ducts, studs and irregular surfaces where batt fiberglass will not fit, but it is not a structural or cavity-fill insulation and will not match fiberglass batts on conductive heat loss. Best for people chasing radiant heat, condensation and noise rather than a full wall R-value.

This reflective foam core insulation is a radiant barrier supplied as a 24" x 100 ft roll, which covers 200 sq ft. It has reflective aluminum foil on each side of a 3 mm (13/64") closed-cell polyethylene foam center.
It prevents 97% of radiant heat transfer and has an R-Value of 15.67 that humidity does not affect. It acts as a vapor barrier and prevents condensation. It is elastic, seals around nails so they do not leak, and keeps its shape over time without collapsing.
It resists UV, does not promote mold or mildew, and does not provide nesting for rodents, bugs or birds. It reduces contact noise by 19 dBA.
