Perlite Insulation Roof

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.

Perlite insulation roof.

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. Expanded perlite s high insulating qualities light weight and versatility make it an essential part of the construction industry for loose fill insulation and lightweight insulating concrete. It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation. Perlite insulation materials are resistant to mold rot and rodents.

Perlite concrete roofdecks offer several important benefits in roofing. It is composed of expanded perlite that is uniformly reinforced with a high strength fiber for use on systems operating up to 1200 f 649 c. Perlite building insulation is produced in a granular or even a powder form but by some manufacturers it is formed into an insulating board by combining perlite with gypsum for example for use under building roofs. The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes.

Sproule wr 1200 is inorganic non combustible and meets or exceeds the physical property requirements of astm. Rigid roof insulation board. It s light weight provides ease of handling.
