| Agricultural perlite |
| Perlite is actually a volcanic glass. It is a very unique and special kind of siliceous rock, in that when heated to extreme temperatures, it expands anywhere from 4 to 20 percent of its size. This expansion is caused by the water molecules inside the rock, which boil and evaporate, leaving tiny holes. This explains why perlite is so lightweight. Another characteristic which evolves from heating, is the normally gray to black rock turns white or light gray. |

Perlite in the Construction Industry Perlite has high insulating abilities, making it useful in many construction materials. For masonry blocks, perlite is poured into the holes, increasing the insulating properties of the concrete. Since it is non-flammable, perlite adds fire protection. Perlite is added to Portland cement, chimney liners, floor insulation, sheet rock, ceiling tiles and many other materials to provide fire protection and reduce sound transmission. Perlite is used in making bricks, which are fired at high temperatures, because of its high heat resistance.
