Perlite Roof Insulation

Typical u values range from 0 21 btu h ft 2 f 1 19 w m 2 k for a 2 inch 50 8 mm 27 lb ft 3.

Perlite roof insulation. Insulating values of a perlite concrete roofdeck depends on the density of the concrete mix that is prepared. All loose and protruding gravel must also be removed. 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. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment.

It s light weight provides ease of handling. Perlite insulation materials are resistant to mold rot and rodents. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. It is also widely used as a separation board over existing roofs in recover installations.

Sproule wr 1200 is a pre formed high temperature non wicking pipe and block insulation. This material is particularly popular as a form of loose fill attic insulation. 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. Energyguard perlite roof insulation is designed to be used directly over structural roof decks.

It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation. 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. 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. In addition to improving thermal resistance perlite insulation also blocks unwanted noise to keep the inside of the home quieter.

Perlite roof insulation its insulating efficiency. Rigid roof insulation board. In recover applications all wet areas of the old roof must be removed. It is composed of expanded perlite that is uniformly reinforced with a high strength fiber for use on systems operating up to 1200 f 649 c.
