GMS 65
mineral foam

The GEOLYTH GMS 65 was intensely undergoing a long term research process. Now, due to its extreme light weight [density: 65 kg/m³] and breathable structure, the mineral foam is able to compete on a high level of effectiveness. Not only in terms of heat- insulation capabilities [thermal conductivity: 0,035 W/mK] and sound absorbing qualities, but also in terms of fire resisting capabilities. The mineral foam is totally incombustible [A1] and does not need any form of external heat source to harden, once it is applied in liquid form. Therefore, the production of the foam is low in energy consumption and reduces the general CO2 footprint of the finished object. The foam itself is primarily used as a filling for hollow block stones and clay bricks. Through its smart formula, the foam does not lose its shape. It remains geometrically stable, even when cut or processed.
