Perlite is one of the most overlooked insulating materials, especially as it offers numerous advantages over other organic and inorganic insulation materials. In an era of growing concern for the impact that building materials and products have on the environment, the choice of which materials to use is increasingly informed by relative performance and sustainability metrics. An extensive review of …
Perlite in Sound Insulation Applications
Discover the many sound-blocking and sound-absorbing uses for expanded perlite. When it comes to noise protection in buildings, both sound-absorbing and sound-blocking (or soundproofing) materials come to mind. Each offers unique properties that make them suitable for specific applications. Processes that Govern the Absorption of Sound by Acoustic Materials First, in porous materials, sound energy is transformed into heat by …
Perlite Insulating Concrete Pool Base for In-ground Vinyl Pools
A perlite insulating concrete pool base can substantially reduce heat loss to the ground Perlite ore, when expanded, takes on a low-density cellular structure that makes it an extremely efficient insulation material. For a detailed explanation of perlite expansion, see PDF info sheet: Why Perlite Works. Perlite insulating concrete pool base can substantially reduce heat loss to the ground thus …
Perlite for Non-Evacuated Cryogenic and Low Temperature Service
The physical character of expanded perlite lends itself to a variety of special purposes –including use in insulating cryogenic and low temperature storage tanks, in shipping containers, cold boxes, test chambers, and in food processing. For a detailed explanation of perlite expansion, see info sheet: “Why Perlite Works” in the information library at www.perlite.org Storage temperatures of -150F (-l00C) and …
Perlite Loose-Fill Masonry Insulation
Perlite, an inorganic material, is as permanent as the walls it insulates. The physical character of expanded perlite lends itself to a variety of special purposes – including use as loose-fill masonry insulation. For a detailed explanation of perlite expansion, see information sheet: “Why Perlite Works“ PROPERTIES & BENEFITS Insulation: Thermal performance tests have shown significant energy savings when perlite is …
Perlite Cement-based Lightweight Insulating Plasters
Perlite cement plaster is thermal and sound insulating, fire retardant, and extremely lightweight—weighing approximately 60% less than ordinary sand plaster. Perlite Cement-based Plaster Perlite cement-based plaster can be used on new or remodel work, as a basecoat for stucco finishes, and as a substrate for ceramic tile or masonry veneer. It can be applied over metal or wire lath, on …
