Modern Bioclimatic Architecture seeks for natural and neutral products to improve building functions and reduce their environmental footprint. Expanded Perlite as a natural mineral meets the highest of Engineering’s standards and delivers exceptional thermal and accoustic insulation on floors, roofs and walls. It is a non–combustable, neutral, odourless and lifetime natural mineral.

The above characteristics, along with the fact that the energy consumed in the process is low, make perlite an ECO-CLEAN product.
