Sauna Aluminum Foil Mesh Tarp Vapor Barrier - 275 Sq Ft

Aluminum foil radiant barrier for sauna walls and ceiling. Reflects the heater's radiant heat back into the room instead of letting it sink into the framing, which means less wasted electricity and a faster warm-up.

Dimensions: 48-inch wide roll, 275 square feet total. Enough to cover a 7' x 7' sauna room with margin for overlap at seams.

Construction: aluminum foil face with mesh tarp backing. The mesh stops the foil from tearing during install; the foil does the reflecting.

Why this instead of polyethylene: poly works as a vapor barrier but adds no radiant reflection. Mesh-backed foil does both jobs in one layer.

Install: foil side toward the sauna interior, mesh side against the studs. Tape seams with foil tape for full vapor sealing.
