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 insulation roof.
It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation.
Or inorganic which includes glass fibers lightweight insulating concrete perlite cellular glass and mineral wool board.
In recover applications all wet areas of the old roof must be removed.
Perlite may even be added into the asphalt mixture on a standard asphalt roof to improve insulation and fire resistance.
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.
The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.
Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment.
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.
It is also widely used as a separation board over existing roofs in recover installations.
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.
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.
It may be used to line refrigerators for food storage or to build trucks used for shipping frozen goods.
Cement stucco perlite is used extensively as a lightweight aggregate material in concrete stucco as it offers thermal insulation fire resistance and more.
It s light weight provides ease of handling.
Rigid board insulation mechanically fastened to the metal deck.
Sproule wr 1200 is inorganic non combustible and meets or exceeds the physical property requirements of astm c610.
Green roof soils perlite is great for green roof soils because it is lightweight low maintenance holds water and nutrients and is cost effective.
Rigid board insulation can also be classified as organic consisting of wood foamed plastics and fiberboards.
Perlite roof insulation its insulating efficiency.
Outside of the construction industry perlite insulation is often used in very low temperature applications.
Insulating values of a perlite concrete roofdeck depends on the density of the concrete mix that is prepared.
Rigid roof insulation board.
Sproule wr 1200 is a pre formed high temperature non wicking pipe and block insulation.
