Eternabond AlumiBond - 4 in. x 50 ft.

For use on virtually all roofs, walls, floors, gravity tanks, troughs, etc. UV stable and moisture tight, AlumiBond creates an air and vapor barrier. The thick 4mm aluminum backing combined with EternaBond's advanced MicroSealant creates a hard surface. AlumiBond bonds to a wide variety of materials, including carbon steel, aluminum, galvanized steel, aluminum foil, gypsum board, wood, rubber, tar, polyethylene, polypropylene, polystyrene, fiberglass, brick, concrete, masonry, rubber, thermoplastics, single-ply roofing, etc. AlumiBond remains flexible to temperatures as low as -70° F making it virtually impossible to thermally shock the roof causing a leak.
