Perlite

Perlite

Perlite ore is a glassy siliceous volcanic rock. When heated to fusion temperature, the molten grains expand into lightweight multicellular particles four to twenty times their original volume. The resulting particles are sized and graded for specific uses, the most common of which are masonry block fill and attic insulation. Perlite is palletized with 30 bags per pallet and stretch wrapped.
