It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation. In recover applications all wet areas of the old roof must be removed.

Perlite insulating concrete consists of an appropriate mixture of portland cement perlite aggregate and water. Typical physical characterictics of perlite. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. Ga gafo 1 80 0 roof 4 11 energyguard perlite roof insulation description smolder if ignited.

Energyguard perlite roof insulation is designed to be used directly over structural roof decks. Rigid roof insulation board. If ignited energyguard perlite roof insulation is a homogenous board composed of expanded perlite particles selected binders and cellulose fibers which give energyguard perlite roof insulation its insulating efficiency. Perlite has a typical density of 3 4 pounds per cubic foot in building insulation products and is described by various industry sources as inexpensive and dimensionally stable doesn t shrink and non combustible.

Perlite as a non fibrous non asbestos green building material. 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. 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. Typical density is 27 lb ft3 432 kg m3.

Expanded perlite can be manufactured to weigh as little as 2 pounds per cubic foot 32kg m 3 making it adaptable for numerous applications. Its weight can be varied in the range of 20 to 50 pounds per cubic foot depending on the mix design selected. 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. Lightweight perlite insulating concrete is light in weight ranging from about 20 40 lb ft3 320 640 kg m3 depending on the desired density and insulating value.
