The inorganic materials are expanded silicaceous volcanic glass which is added to organic wood fibers and bonded with asphaltic binders.
Perlite board for built up roof.
It s light weight provides ease of handling.
Fescant plus cant strips.
Perlite is also a fibrous insulation board that contains both inorganic and organic materials.
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.
Perlite also changes dimensions when it becomes wet.
A built up roof for example will typically include the built up membrane itself with or without gravel as well as some kind of insulation and cover board which will vary in thickness from roof to roof.
Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof.
The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.
Homogenous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency.
Economical base for reroofing.
Properly installed energyguard perlite roof insulation is suitable for use.
Properly installed energyguard perlite recover board roof insulation is suitable for use under built up modified bitumen and some single ply roofing systems.
Built up roofing may then be immediately applied by flood coating the surface with hot asphalt.
Bitumized perlite is an excellent material for repair of existing roofs as it can usually be applied over structurally sound roofs that have been swept clean of loose debris and coated with a cold asphalt adhesive layer.
It is also widely used as a separation board over existing roofs in recover installations.
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.
Energyguard perlite roof insulation is designed to be used directly over structural roof decks.
Lower installed cost than tear offs.
The minimum recycled content is 25 by weight.
This specification covers the composition and physical properties for perlite thermal insulation board used principally above structural roof decks and as a base for built up modified and elastomeric membrane roofing in building construction.
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.
Rigid roof insulation board.
Excellent for transitioning from membrane to nailer or transitioning from tapered fesco tapered enrgy 3 or tapered fesco foam panels to the roof level to help promote positive drainage.
