Perlite Insulation Roofing Board

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.

Perlite insulation roofing board.

The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes. 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. Additionally densdeck has been shown to withstand de lamination deterioration warping and jobsite damage more effectively than other roofing membrane substrates such as paper faced gypsum board fiber board and perlite insulation. Rigid roof insulation board.

Expanded perlite is suitable for a range of landscaping applications such as green roof construction golf green renovation and construction planters drainage. Johns manville s solution is an expanded perlite product with a built in corrosion inhibitor. Perlite is a volcanic glass that expands due to the water content in the ore the material is often processed with wood fibers and binders to produce rigid boards. Energyguard perlite recover board description energyguard perlite recover board is a heavy duty 1 2 thick perlite roof insulation board composed of expanded perlite cellulose binders and waterproofing agents.

Perlite roof insulation description energyguard perlite roof insulation is a homogeneous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes. 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.

It s light weight provides ease of handling. Sitek specialises in the manufacture of fesco expanded perlite insulating boards and batiboard products for the construction industry. Energyguard perlite roof insulation is a homogenous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency. Combined with resistance to water absorption sproule wr 1200 perlite effectively minimizes corrosion to outer pipe surfaces and equipment while providing excellent thermal insulation.
