Rigid roof insulation board.
Perlite roof insulation.
Sproule wr 1200 is inorganic non combustible and meets or exceeds the physical property requirements of astm c610.
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.
In addition to improving thermal resistance perlite insulation also blocks unwanted noise to keep the inside of the home quieter.
The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.
This material is particularly popular as a form of loose fill attic insulation.
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.
Energyguard perlite roof insulation is available in 2 x 4 610 mm x 1 22 m and 4 x 4 1 22 m x 1 22 m boards in standard thicknesses of 3 4 1 11.
Energyguard perlite roof insulation is designed to be used directly over structural roof decks.
All loose and protruding gravel must also be removed.
It is also widely used as a separation board over existing roofs in recover installations.
Typical u values range from 0 21 btu h ft 2 f 1 19 w m 2 k for a 2 inch 50 8 mm 27 lb ft 3.
Insulating values of a perlite concrete roofdeck depends on the density of the concrete mix that is prepared.
Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment.
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.
Sproule wr 1200 is a pre formed high temperature non wicking pipe and block insulation.
Perlite roof insulation its insulating efficiency.
Perlite insulation materials are resistant to mold rot and rodents.
And the green community recognizes perlite enhanced products like lightweight insulating concrete roof decks as a high performance solution drawn from a natural material of nearly unlimited supply throughout the world.
In recover applications all wet areas of the old roof must be removed.
