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.

Asphaltic a mixture of minerals and asphalt with a fiberglass facer. Composed of expanded perlite reinforcing cellulosic. Composed of a closed cell polyisocyanurate foam core bonded in the foaming process to 1 2 thick duraboard an expanded perlite mineral aggregate board on one side and a fiber glass reinforced facer on the other. Energy and the environment.

Perlite based cover board refer to the safety data sheet and product label prior to using this product. Even though the r value of perlite is low it is often used as a component in multi layered systems or as a cover board in built up and modified bitumen membrane roof systems. Provides good dimensional stability excellent insulation value with stable r value and fire resistance. Perlite volcanic materials combined with minerals fibers and cellulose binders.

Rigid roof insulation board. Structodek is lightweight compared to many other roofing cover boards and it is fiberglass free and cuts with a standard utility knife. When used as a cover board it needs a surface coating to prevent excessive absorption of asphalt as well as blistering. Superior dimensional stability over competitive gypsum fiber boards is due to their low coefficient of thermal and hygrometric expansion.

Plywood osb compressed layers of wood bound with a resin sometimes with veneer. Mineral fiber compressed rock wool or mineral fiber. It s light weight provides ease of handling. High density expanded perlite based cover board engineered to optimize system performance across all applications.

Stocked in 12 locations around the country to facilitate job start ups and completions structodek is available in 4 x4 and 4 x8 boards w56 358 8531 for a 4 x4 x board and w56 358 8532 for. Top surface is sealed with this special coating to reduce excessive asphalt absorption in hot asphalt applied roofing systems. Low thermal insulation board. 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.

It is treated for surface retention of bitumen and available in 2 x 4 0 6m x 1 2m 4 x 4 1 2m x 1 2m and 4 x 8 1 2m x 2 4m with a nominal thickness of 1 2 13mm. The inorganic materials are expanded silicaceous volcanic glass which is added to organic wood fibers and bonded with asphaltic binders.
