2-hour fire protective boards for the assembly of your smoke extraction and ventilation ducts


During a fire, the smoke that spreads inside a building is the main cause of fire victims. The toxicity and temperature of the smoke, linked to the speed at which it travels, prevent occupants from evacuating safely.

GEOTEC®S30 and GEOTEC®S45 boards allow you to integrate smoke extraction and ventilation ducts directly into your premises in order to sweep the space to be smoked out with a flow of air.

These boards, mainly made of plaster and fibreglass, are natural products and CE certified. GEOTEC®S boards meet the fire resistance classification standards EN 13501-2, EN 13501-3 and EN 13501-4 and comply with current European legislation concerning the conformity of fire-resistant products for passive fire protection.
