It s light weight provides ease of handling.
Perlite insulation roof.
The surface is treated to reduce bitumen absorption assuring proper adhesion of roof membranes.
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.
Perlite concrete roofdecks offer several important benefits in roofing.
It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation.
Rigid roof insulation board.
As perlite concrete roofdecks are seamless they provide a monolithic base for roofing that is smooth and even.
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.
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.
Sproule wr 1200 is inorganic non combustible and meets or exceeds the physical property requirements of astm.
Sproule wr 1200 is a pre formed high temperature non wicking pipe and block insulation.
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.
