Perlite Board For Built Up Roof

It is also widely used as a separation board over existing roofs in recover installations.

Perlite board for built up 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. Built up roofing may then be immediately applied by flood coating the surface with hot asphalt. The minimum recycled content is 25 by weight. Properly installed energyguard perlite recover board roof insulation is suitable for use under built up modified bitumen and some single ply roofing systems.

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. 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. 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.

The inorganic materials are expanded silicaceous volcanic glass which is added to organic wood fibers and bonded with asphaltic binders. 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. Properly installed energyguard perlite roof insulation is suitable for use. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.

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. Rigid roof insulation board. Even though the r value of perlite is low it is often used as a component in multi layered systems or as a cover board in built up and modified bitumen membrane roof systems. Homogenous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency.

Energyguard perlite roof insulation is designed to be used directly over structural roof decks. It s light weight provides ease of handling. Lower installed cost than tear offs. Perlite is also a fibrous insulation board that contains both inorganic and organic materials.

Fescant plus cant strips. Tapered fesco edge strips. Economical base for reroofing.
