Home > Main Index > Markets > Construction Applications > Construction Uses of PerliteConstruction Uses of Perlite Perlite has been used for years as
an aggregate in lightweight, insulating concrete and plaster, and as a loose fill
insulation material for concrete masonry blocks, cavity walls, and in residential homes.
It is also are used in a variety of specialty applications ranging from fireproofing
sprays, chimney fills, interstitial floors, acoustical sprays, etc. Perlite is used as loose-fill insulation in the construction of modern, insulated masonry wall systems. And not only do they significantly increase the tested "R" values of these walls, they also can help change the fire rating of many walls from a basic 2-hour fire rating to a 4-hour rating.

Most of these products are patented and sell under brandnames, but this page gives a basic outline of why and where these two lightweight, fire-proof aggregates are used. Under Floor Sound and Thermal Insulation In Germany, Denmark, and the Netherlands, perlite loose fill is used on new and existing floors for both accoustical insulation and thermal insulation. Sometimes called a "floating floor," these floor systems are used extensively in these Northern European countries, but not yet in America. Underfloor Accoustical Insulation |
