A composite sheet material exhibiting a low emittance characteristic at both of its outer surfaces for limiting radiant heat transmission therethrough comprises one composite sheet structure including a base layer of sheet material having high strength, resistance to tearing, stability, and body, and a first layer of material having a low emittance characteristic disposed in intimate contact with one surface of the base layer. A second composite sheet structure includes a protective layer of sheet material that is generally transparent to radiant energy in the infrared range of the energy spectrum and a second layer of material having a low emittance characteristic disposed in intimate contact with one surface of the protective layer. The composite sheet structures are bonded together with the second layer of material having low emittance facing the other surface of the base layer, that is with the first layer of material having low emittance forming one outer surface of the composite sheet material and the protective layer forming the other outer surface.

A composite flexible, rollable sheet material having a low emittance characteristic at both of its outer surfaces for limiting radiant energy transmission therethrough comprising: a base layer of flexible, rollable, high strength, tear resistant material, an outer layer, disposed in intimate contact with one surface of said base layer, having a low emittance characteristic; a protective layer of flexible, rollable material dissimilar from said base layer material and substantially transparent to radiant energy in the infrared range of the energy spectrum; an intermediate layer disposed in intimate contact with one surface of said protective layer, also having a low emittance characteristic; and bonding means for intimately joining said intermediate layer to said base layer.
