Roof Cover Board Perlite

Energyguard perlite recover board is a heavy duty 1 2 thick perlite roof insulation board composed of expanded perlite cellulose binders and waterproofing agents.

Roof cover board perlite.

High density expanded perlite based cover board engineered to optimize system performance across all applications. Perlite also changes dimensions when it becomes wet. Superior dimensional stability over competitive gypsum fiber boards is due to their low coefficient of thermal and hygrometric expansion. Composed of expanded perlite reinforcing cellulosic.

Mineral fiber compressed rock wool or mineral fiber. The inorganic materials are expanded silicaceous volcanic glass which is added to organic wood fibers and bonded with asphaltic binders. Plywood osb compressed layers of wood bound with a resin sometimes with veneer. When used as a cover board it needs a surface coating to prevent excessive absorption of asphalt as well as blistering.

Shown to withstand delamination deterioration warping and job site damage far more effectively than paper faced gypsum board and other conventional roofing products such as wood fiberboard and perlite certified by ul for use as a fire barrier over combustible and noncombustible decks in accordance with the ansi ul 790 and ulc s114 test standard. Asphaltic a mixture of minerals and asphalt with a fiberglass facer. Perlite is also a fibrous insulation board that contains both inorganic and organic materials. Meets the requirements of astm c 728 type 1.

Low thermal insulation board. Provides good dimensional stability excellent insulation value with stable r value and fire resistance. Rigid roof insulation board.
