How to divide the Combustion Performance of Thermal insualtion material?

1. Class A: Non-combustible building materials: materials that hardly burn.

2. Class B1: Flame-retardant building materials: Flame-retardant materials have good flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, it is not easy to spread quickly, and the combustion stops immediately when the fire source is removed.

3. Class B2: combustible building materials: combustible materials have a certain flame retardant effect. When exposed to an open flame in the air or under high temperature, it will immediately catch fire and burn, which may easily lead to the spread of fire, such as wooden pillars, wooden roof trusses, wooden beams, wooden stairs, etc.

4. Class B3: Flammable building materials: Without any flame retardant effect, it is extremely flammable and has great fire risk.

The glazed foamed ceramic thermal insulation decorative integrated panel and thermal insulation coating developed by ZANSHARE are advanced green energy-saving building materials, and the combustion level is A+ level, safe and durable!
