Depending upon design conditions, reductions in heat transmission of 50 percent or more can be obtained when perlite loose fill is used in the hollow cores of concrete block or cavity type masonry walls. "Water retention properties of perlite as a material with crushable soft particles." 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. 3 (2008): 539-552. Some writers name perlite insulation products as a "green building material", probably because it is a natural, mined resource (not considering the energy costs of mining and production), and more, because perlite is used as a concrete additive to make insulating and light-weight concrete, or as an insulating material to fill the cores of masonry block constructed walls. Redco II sells perlite for horticultural purposes (those white particles you see in some brands of potting soil), for industrial and construction applications such as an additive in the formation of concrete, and for general industrial uses including as a filtering medium. Sproule WR-1200® is a pre-formed, high-temperature, non-wicking pipe and block insulation. Insulation Products description - Perlite Canada. It is also used to insulate air-separation plants, vacuum and non-vacuum small tanks and small tanks and small cold and hot storage containers like flasks.
