Perlite Board For Built Up Roof

Homogenous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency.

Perlite board for built up roof.

The inorganic materials are expanded silicaceous volcanic glass which is added to organic wood fibers and bonded with asphaltic binders. The minimum recycled content is 25 by weight. 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. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.

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. Economical base for reroofing. Rigid roof insulation board. Perlite also changes dimensions when it becomes wet.

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. Tapered fesco edge strips. 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. Lower installed cost than tear offs.

It is also widely used as a separation board over existing roofs in recover installations. Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof. 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. 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. 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. Fescant plus cant strips. Built up roofing may then be immediately applied by flood coating the surface with hot asphalt.

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. When it comes to estimating the weight of an existing roof field verification of the in place construction is necessary.
