Abstract: The pliable building membrane (1) is a non-flammable inorganic fabric (2) defining a first planar side (4) and a second opposite planar side (5). A halocarbon polymer in the form of a fluorocarbon polymer (3) is impregnated into the first planar side (4). The halocarbon polymer may be polytetrafluoroethylene (PTFE), fluorin plastic, ethylene tetrafluoroethylene and/or a tetrafluoroethylene perfluoro propylene co-polymer, for example. Various embodiments have differing ratios of halocarbon polymer to non-flammable fabric and this influences its vapour permeability. A suitable minimum target vapour permeability is approximately 0.15 µg/N.s. An embodiment having a 1:1 ratio has a vapour permeability of approximately 1 µg/N.s, which is well suited for use as a sarking-type material. The non-flammable fabric (2) may be a satin-weave fiberglass fabric or other non-flammable fabrics, such as basalt fibre fabric, or carbon fibre fabric, for example.
