GEOLYTH vacutec 100 is a thermal expanded perlite (obsidian), whose volume is increased by the 10- to 20th of its original form. In fact, a technical vacuum arises inside the cell due to a patented physical enlargement process. However, the expanded cell remains closed and does not crack during the deformation. It enables the cell to reduce its thermal conductivity level (0,048 W/mK) and withstand the absorbtion of water. Due to its mineral origin, the expanded perlite remains incombustible (A1).
