Perlite Roof Insulation

Perlite insulation materials are resistant to mold rot and rodents.

Perlite roof 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. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. All loose and protruding gravel must also be removed. Perlite building insulation is produced in a granular or even a powder form but by some manufacturers it is formed into an insulating board by combining perlite with gypsum for example for use under building roofs.

It s light weight provides ease of handling. 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. Sproule wr 1200 is inorganic non combustible and meets or exceeds the physical property requirements of astm c610. It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation.

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. Sproule wr 1200 is a pre formed high temperature non wicking pipe and block 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. 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. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. In recover applications all wet areas of the old roof must be removed. Many builders and homeowners rely on perlite insulation to block unwanted airflow in walls roofs and foundations.

In addition to improving thermal resistance perlite insulation also blocks unwanted noise to keep the inside of the home quieter. 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. Rigid roof insulation board. This material is particularly popular as a form of loose fill attic insulation.
