| 保温材料防火等级 Insulation material fire resistance grade 在我国,外墙保温材料主要被分为A级、B1级、B2级和B3级四个等级，A级为不燃材料，属无机保温材料。B级的保温材料，分为三个等级，B1级是难燃，B2级是可燃，B3级是易燃。 In our country, the exterior wall insulation material mainly is divided into grade A, B1, B2 and B3 class, grade A is non-combustible material, it is an inorganic heat preservation material. Class B insulation material is divided into three levels, B1 is incombustible, B2 is combustible, B3 is flammable. B1级：比较常见的如经过特殊处理加了阻燃剂的EPS/XPS保温板等。B2级：可燃保温材料，多见为EPS膨胀聚苯泡沫保温板与XPS挤塑板，也就是我们常说的普板。这种材料燃点低，并在燃烧过程中会释放大量有害气体。 Level B1: the EPS/XPS insulation board that is commonly used for special treatment and flame retardant. Class B2: combustible insulation materials, seen as EPS expansion polystyrene foam insulation board and XPS extrusion board, which is what we call the plywood. The material burns low and releases a lot of harmful gases during the burning process. B3级：易燃保温材料，这种多见为聚苯泡沫为主材料的保温材料，由于这种材料极易燃烧，目前已是被淘汰的外墙保温材料。 B3 level: combustible insulation material, the rare thermal insulation material for polystyrene foam gives priority to material, because this kind of material easy to burn, is already the elimination of exterior wall thermal insulation material. |
