GRANUGLASS – the highest quality of granulate

Perlite Granuglass is a light and porous material derived from the natural mineral perlite. Perlite is a type of volcanic lava glass, and the expansion process involves heating it to a very high temperature. As a result, the perlite is sintered into glass granulate, which leads to the creation of a light and porous product for various applications.

The perlite vitrification process involves heating it to a temperature of about 870-1100 degrees Celsius, which causes the water contained in the minerals to be converted into steam. This phenomenon causes the vitrification of Perlite into small spherical particles. As a result, a light material with a structure with micro-bubbles of air is obtained.
