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.

Perlite insulation roof.

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

In addition roofing membranes may be adhered directly to the perlite concrete roofdeck or base sheets for built up roofing may be nailed directly to the perlite. 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. Perlite concrete roofdecks offer several important benefits in roofing. The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes.

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. 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.
