Tecwool® 825 is a mortar made of rook wool, cement and small amounts of heat-resistant material manufactured by mercortecresa® and specifically designed for fire protection for industrial applications and tunnels. Its cement content makes it highly robust. It looks like a monolithic block resistant to erosion and semi-exposed or partially covered areas.
Tested under hydrocarbons curve, RWS curve and American UL standards, Tecwool® 825 has been subjected to simulations to evaluate fires at high temperatures during a long period of time.
Tecwool® 825 adapts to a wide variety of supports, even when exposed to settlement vibrations or movements. No cracking or crazing as a result of its perfect adherence and flexibility.
Due to its alkalinity, the product resists fungi, does not corrode steel or release toxic or flammable vapour.
