Perlite Board For Built Up Roof

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 board for built up roof.

It is also widely used as a separation board over existing roofs in recover installations. The minimum recycled content is 25 by weight. Perlite also changes dimensions when it becomes wet. Perlite is also a fibrous insulation board that contains both inorganic and organic materials.

The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. Economical base for reroofing. 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. 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. When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary. Properly installed energyguard perlite recover board roof insulation is suitable for use under built up modified bitumen and some single ply roofing systems.

Energyguard perlite roof insulation is designed to be used directly over structural roof decks. 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. 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. Properly installed energyguard perlite roof insulation is suitable for use.

Fescant plus cant strips. Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof. Lower installed cost than tear offs. 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.

Tapered fesco edge strips. It s light weight provides ease of handling. 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.
