A composite flexible fabric is employed as a covering for an opening of a building, such as a window or door. The composite fabric protects the opening from hurricane force winds and associated flying objects. The composite fabric is formed from at least one layer of a fabric comprised of high tenacity fibers and at least one ultraviolet radiation resistant layer which is attached to the high tenacity fiber fabric. The UV resistant layer limits transmission of both UVA and UVB rays preferably to less than about 10% of the radiation incident upon such layer. Preferably, the UV resistant layer is a woven fabric, and the layer of high tenacity fibers is a woven fabric of extended chain polyethylene fibers. An adhesive layer may be used to enhance bonding between the fabric layer and the UV resistant layer.
