INPRO Loose Fill Perlite insulation is an inert volcanic glass expanded by a special heat process. The resultant lightweight product is a white granular material that handles and pours easily. It provides a quick, inexpensive and permanent method for efficiently insulating masonry walls. Depending upon design conditions, reductions in heat transmission of 50% or more may be obtained when perlite loose fill is used in the hollow cores of concrete block or cavity type masonry walls (Perlite Institute Inc. 1989). Properties Thermal Insulation INPRO Perlite has shown it to be the superior concrete block insulation when compared to expanded polystyrene (EPS) inserts by 22%, expanded EPS beads and vermiculite. Containing countless tiny air cells that account for its excellent thermal insulation and light-weight, the efficiency and economy of loose fill perlite has been proven many years in the insulation of storage tanks for liquid gases such as oxygen, liquid natural gas and nitrogen at temperatures as low as 240°c. Inorganic INPRO Perlite is inorganic and therefore is rot, vermin and termite resistant and non-combustible with a fusion point of approximately 1260°c. It is as permanent as the walls containing it. Non-settling INPRO Perlite loose fill supports its own weight in the wall without settling as verified by actual field measurements. (Perlite Institute, Inc. 1989). Flow ability INPRO Perlite consists of granules that are free flowing to seek out and completely fill the smallest crevices and mortar areas without bridging. Price Competitive
