Lightweight Fills and Thermal Insulating Layers 2.2.8 Lightweight fills are used primarily on Intensive Green Roofs to create differences in level.
But due to major presence of inorganic constituents, the sorption capacity of green roof substrate is always limited. For instance, expanded perlite, a widely used substrate component, exhibited only 8.6 and 13.4 mg/g sorption capacities over Cu(II) and Pb(II) ions, respectively .
2020510&ensp·&enspPerlite use as filtering media in rain water conservation from roof top and gutters, similar use in aqua pond water treatment plants and aquarium. Food industries use in beer and oil filtering. Insulation use casts as light weight bricks with cement or silie binder into fire bricks.
In Canada, the applicable standard for fibreboard roof insulation is CAN/CSAA247M, "Insulating Fibreboard". 1. Perlite Roof Board . Perlite roof insulation has been widely used in the US since the 1950's, and is finding increased usage in Canada. Perlite boards are composed of expanded perlite ore, cellulose fibres, asphalt and starch

Lesscombustible roof insulations, such as perlite and glass fiber, could meet FM requirements with limited quantities of bitumen, generally applied in ribbons directly to the deck. Nonbituminous vapor retarders, such as PVC, glued to the deck with polymeric adhesives were introduced as well.
The insulating mortar perlite expanded furnace was successfully invented in Feb 2003. In the same year, it obtains the patent in practice and in creativity, and the first furnace was brought into commercial process in the world. 300 sets of them

Perlite concrete Perlite is a type of lava mined in l a r ge open pits in the We s t e r n Un i t ed St a t e s, then crushed to sand s i z ed part i c l e s, and expanded by h e a t i n g . Perlite insulating concrete is a m i x t u r e of expanded perlite, portland cement, water and an air e n
202058&ensp·&enspIt is essential that the expanded perlite, cement and airentraining admixture are accurately proportioned and the mixing time carefully controlled. The strength figures given in this data sheet are those obtained when the screed is tested by the methods of BS EN 1015 PART 11. In practice dry strengths are likely to be higher.
The dry density is down around 30 pcf it achieves this low weight by the use of expanded aggregates such as perlite and vermiculite (airentraining agents), or both. While this product has somewhat better insulating qualities, for new construction, it invariably incorporates expanded polystyrene foam for today's necessary high Rvalues.
Perlite is a volcanic glass that expands due to the water content in the ore.The material is often processed with wood fibers and binders to produce rigid boards. Even though the Rvalue of perlite is low, it is often used as a component in multilayered systems, or as a cover board in builtup and modified bitumen membrane roof systems.
The information sheets below are an indepth collection of the research, tests, applicable uses, and technical data the Perlite Institute and its members have compiled and published for perlite, grouped by industry. For more information about these uses or other uses for perlite, please contact the Perlite Institute member nearest to you.
Perlite thermal insulation board is classified as follows: type 1 roof insulation board, and type 2 roof cover/recover board. The basic material of the insulation board shall be perlite expanded by the appliion of heat to form glassy, cellular aggregates. The
