Perlite is a naturally occurring siliceous rock of volcanic origins. When heated to more than 1000-C it expands up to several times its original volume and thus creating the premises of light weightiness and thermal insulating properties. The indoor comfortable climate of modern lifestyle requires large amounts of energy to be created and sustained. This, in turn, leads to large amounts of CO2 being released in the atmosphere. Continuous research efforts are invested in creating materials with good insulation prop...
