Perlite's lightweight, insulating, and fire-resistant properties make it a valuable material in construction, especially in applications where weight reduction and insulation are important factors. It is a cost-effective choice for enhancing the energy efficiency, fire safety, and overall performance of buildings and construction projects.

Perlite can be mixed with plaster or stucco to create lightweight, textured finishes for interior and exterior walls. Perlite-enhanced plaster is easier to apply and provides improved thermal insulation. Perlite is often used as an aggregate in lightweight masonry blocks, bricks, and mortar. These lightweight masonry products are easier to handle and transport
