    Abstract: A flexible composite laminate, which is fire resistant on either one or both sides, comprises: (a) a textile web substrate; and the following combination of successive layers on either one or on both sides of the substrate, namely: (b) a first discrete adhesive layer, to provide adhesive bonding between substrate (a) and a layer (c); (c) a layer superimposed upon the first discrete adhesive layer, which comprises at least one fire-resistance imparting inorganic substance in an amount effective to impart fire-resistance to a preselected degree to the substrate; (d) a second discrete adhesive layer on layer (c), to provide adhesive bonding between layer (c) and a sealing layer (e), as defined below; and (e) a hydrophobic sealing layer superimposed on the second discrete adhesive layer. The first adhesive layer may be optionally omitted when the substrate is a fiberglass substrate, and/or the second adhesive layer may be optionally avoided when the hydrophobic sealing layer is silicone-based. When layer (e) is e.g. PVC, it is found that the emission of smoke is reduced as compared with unlaminated PVC.
