Abstract: The invention relates to a halogen-free flameproof mesh sheet for use outdoors. The flameproof sheet contains a flame retardant which does not have an increase in viscosity during storage, has excellent gloss and flexibility, and does not generate harmful halogen gas at the time of combustion. A mesh sheet woven out of a coated yarn, typically a multifilament fiber, is impregnated with the flame retardant and heat treated. The fabric is impregnated with the flame retardant such that 60-350 parts by weight of the flame retardant is contained with respect to 100 parts by weight of the mesh sheet fabric. The flameproof mesh sheet are suitable for use in building construction and is suitable for outside exposure for extended lengths of time.
