Perlite in Construction

Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. And the green community recognizes perlite-enhanced products—like lightweight insulating concrete roof decks—as a high-performance solutions drawn from a natural material of nearly unlimited supply throughout the world.

Construction Industry:
Big Users of Perlite

Research suggests that more than 50 percent of expanded perlite worldwide is used by the construction industry. Perlite plays an important role in a wide variety of construction-related uses including: as an aggregate in lightweight insulating concrete and plaster; as a loose fill insulation material for concrete masonry blocks, cavity walls, in residential homes; and in a variety of specialty applications including fireproofing sprays, chimney fills, interstitial floors, acoustical sprays, etc. See our Perlite House PDF to see some of the ways perlite is used in construction.
