Suberglass is a lightweight insulating mixture for thermal and acoustic insulation of attics, two versions are available:

-Suberglass 70 to obtain a very light, very insulating and economically advantageous insulating layer.

-Suberglass 90 to obtain a more robust and walkable substrate.

The granulate is mixed with sodium silicate: a natural agglomerating liquid that solidifies the layer without excessively altering the insulating power of the cork.

Layers are formed from 7 cm up to 20 cm and above. If the dough is leveled and compacted correctly it is occasionally walkable.

To pave the surface it is necessary to create a top layer of concrete or other pavable material.
