Foster® MAST-A-FAB® WHITE Reinforcing Membrane 42-24 features a synthetic fiber composition that offers enhanced elongation, recovery, and resistance to stress breakage. This membrane's leno weave design ensures fabric stability, eliminating the typical thread movement and distortion found in plain weave cloths. Importantly, it has no discernible impact on the flame spread and smoke-developed ratings of the chosen mastic or coating.
