Phenolic insulation board fire rating

Phenolic insulation board of fireproof rank all know phenolic board has good fire resistance, refractory performance is good, but no one dare to say, so we still need to rely on professional exam professional statement and research to find out. Traditional phenolic board not only can be used for exterior insulation system, can be also prepared to act the role of surface composite insulation decoration plate, can also be used to build the traditional EPS/XPS/fire belt, PU external wall insulation system will be used for fire prevention in the curtain wall insulation insulation materials, fire door insulation materials, as well as low or high temperature fire insulation thermal insulation material. Phenolic plate is a new kind of non-combustible low smoke, fire insulation materials, it is made of phenolic resin in foaming agent, curing agent and other additives made of closed-cell rigid foam. It is the most prominent feature of non-combustible, low smoke, resistance to high temperature of different change. It overcomes the original type foam insulation material inflammable, cigarettes, drawback of the metabolic that encounter heat, retained the original type foam insulation material is qualitative light, construction is convenient wait for a characteristic. Phenolic insulation board production convenient, can according to user needs in site construction; Cleaning and hygiene; Using aluminum foil composite sandwich board surface, ensuring the health of air from the duct, the frictional resistance is small, the air quality is high, because the product is called environmental duct. Because the product is made up of aluminum foil ﹢ phenolic foam ﹢ aluminum foil, and therefore has a good sound insulation, vibration resistance dimming and flame retardant, energy-saving features, to reduce the operation cost. Before know fireproof property of the phenolic plate, we need to be aware of the refractory of the phenolic board performance. According to the national standard, the fire resistance rating can be divided into four types, level of refractory is building brick and tile, secondary fire is roof truss of steel structure and mixed structure, the third class cabin fire is building and brick structure, the fourth fire is fire wall and wall. In simple terms, can be divided into class A non combustible, B1 level refractory, B2 flammable, also known as flame retardant, B3 type flammable. In this way, we have general refractory requirements. Phenolic board we come into contact with the fire resistance rating it's experts answer. Because phenolic plate material is mainly phenolic foam, it also combines with other insulating materials use. Basically, it is A class A fire rating of the composite state, that is to say, the best fire rating in A composite state. So that we can safely use phenolic board.
