Perlite Roof Insulation

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 roof insulation.

It s light weight provides ease of handling. Perlite insulation materials are resistant to mold rot and rodents. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. This material is particularly popular as a form of loose fill attic 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. It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation. In addition to improving thermal resistance perlite insulation also blocks unwanted noise to keep the inside of the home quieter.

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. Rigid roof insulation board. Insulating values of a perlite concrete roofdeck depends on the density of the concrete mix that is prepared. 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.

Perlite roof insulation its insulating efficiency. All loose and protruding gravel must also be removed. 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.

It is also widely used as a separation board over existing roofs in recover installations. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. Sproule wr 1200 is a pre formed high temperature non wicking pipe and block insulation. Many builders and homeowners rely on perlite insulation to block unwanted airflow in walls roofs and foundations.
