Perlite roof insulation weight.

Rigid roof insulation board. 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. Since perlite is a form of natural glass it is classified as chemically inert and has a ph of approximately 7. Typical physical characterictics of perlite.

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. It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation. Perlite as a non fibrous non asbestos green building material. In recover applications all wet areas of the old roof must be removed.

Its weight can be varied in the range of 20 to 50 pounds per cubic foot depending on the mix design selected. Because of its lightweight there can be economies in the design of the structure. Energyguard perlite roof insulation is designed to be used directly over structural roof decks. 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.

Expanded perlite can be manufactured to weigh as little as 2 pounds per cubic foot 32kg m 3 making it adaptable for numerous applications.

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. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment.

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 insulating concrete consists of an appropriate mixture of portland cement perlite aggregate and water. It is also widely used as a separation board over existing roofs in recover installations.
