F/R Alum. Foil-Glass Cloth Facing

A flame-retardant Foil-Glass cloth facing (7u foil and 10×9 mesh glass cloth, laminated with F/R glue). It 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. It is also a good choice for radiant barrier applications because of its low emissivity.
