Phenolic board insulation effect has a long history
phenolic board as organic foam insulation, low thermal conductivity, thermal insulation effect is better than general has a-class fire prevention performance of inorganic insulation materials, and fire prevention performance of phenolic foam board itself to reach level b1 level flame retardant, in case of fire only surface carbonization, without dripping, which can effectively prevent fire spreading. This is a traditional organic materials such as polyurethane (pu), polystyrene foam is unable to achieve. Phenolic plate meet flame non-combustible, after the application of wall insulation system can be equivalent grade A fireproof performance. Mortar, phenolic plate composite grid cloth or other material such as spray interface agent, surface recombination adding inorganic material, can achieve a-class fire performance.
