Steico wood fibre insulation boards provide a range of external and internal vapour open insulation solutions as part of Internal Wall Insulation (IWI) and External Wall Insulation (EWI) systems, as well as for roofs and floors.
Fire-protection of structures
Wood burns! There is no denying this fact and it is partially valid for STEICO wood fibre insulating materials. However STEICO insulating materials exhibit some very positive behaviour in the event of fire:
STEICO’s rigid insulation panels don’t need any fire protection additive. Their high density prevents them from burning. Only the flexible and air injected insulation include a natural fire protection additive. The product used is ammonium phosphate, a mineral salt produced from combining the elements phosphorus and nitrogen. Ammonium phosphate is a natural and harmless product, which is frequently used in the food industry. In the event of a fire, a carbonization layer quickly forms on the surface of the insulation board or mat . This carbonisation or charring acts to restrain the propagation of the fire and prevents the fast burning through of the STEICO product. Many conventional insulating materials are prone to melting and offer very limited fire protection or actively contribute to it. In combination with suitable finishes, fire-protection structures to F90 B (a fire would need 90 minutes in order to enter the construction) can be built with STEICO insulating materials. As an organic based material, STEICO insulating materials will not emit toxic gases in the event of fire, unlike many petro-chemical based insulating materials.
