High tensile strength and good abrasive-resistance, and BS 476 Class O Fire-Rating approval.
Aluminum foil facing (7u foil and 10×9 mesh glass cloth, laminated with F/R glue). This laminated insulation facing enjoys high tensile strength and good abrasive-resistance, and BS 476 Class O Fire-Rating approval. It is good as a vapor barrier of duct wrap, duct board and pipe insulation. Very good for industrial and vessel engine room’s thermal insulation. Aluminum foil facing is also a good choice for radiant barrier applications because of its low emissivity.
