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. Like all of our additives, ammonium phosphate is a natural and harmless product, which is frequently used in the food industry.
- In the event of a fire developing, 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. In combination with suitable finishes, fire-protection structures to F90 B (a fire would need 90 minutes, in order to penetrate the construction) can be constructed 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. An important consideration for the fire services.
In summary: Although wood can burn, it still offers the highest degree of fire protection
