Perlite Insulation Board

Though Perlite is a brand name, it is a generic name for natural occurring rock. Volcanic glass is non-crystalline in structure and is composed of silica as well as alumina. The natural tendency of the structure is that when it reaches a particular temperature, the volume will increase close to 20 times the original volume of the product. This expansionist quality of the product is due to the presence of 2 to 6% water content in the ore that gives perlite its characteristic features. This is what makes perlite the most versatile product worldwide.
