怎么判断房子的保温材料防火等级是否达标吗?
来源:/ 日期:2018-08-03 发布人:admin

在选购房产时大多数人总会关注到采光、位置、周边配套、户型、物业管理等因素。然而,您是否有关注到整个建筑防火安全呢?您家的房子用的是什么保温材料呢?防火等级又是如何呢?
When buying real estate, most people will be concerned about lighting, location, surrounding facilities, apartment, property management and other factors. However, are you concerned about the fire safety of the whole building? What's the heat insulation material for your house? What's the fire grade again?
我国建筑材料燃烧等级分类
Classification of combustion grade of building materials in China
根据《GB8624-2012》规范,我国建筑材料燃烧等级分为:
According to the "GB8624-2012" standard, the burning degree of building materials in China is divided into:

A级不燃性材料:又分为A1和A2级
Class a noncombustible material: A1 and A2
B1级难燃材料:又分为B级和C级
B1 grade refractory materials: B and C grade
B2级可燃材料:又分为D级和E级
B2 grade combustible materials: D and E levels
B3级易燃材料
B3 flammable material
内保温系统防火要求
Fire protection requirements of internal heat preservation system
采用内保温系统的建筑外墙,其保温系统应符合下列要求:
The insulation system of building exterior walls with internal insulation system should meet the following requirements:
1、对于人员密集场所,用火、燃油、燃气等具有火灾危险性的场所以及各类建筑内的疏散楼梯间、避难走道、避难闻、避难层等场所或部位,应采用燃烧性能火A级(不燃)的保温材料。
1. For places of fire, fuel, gas and other places with fire hazards, evacuation staircases, asylum passages, refuge smells and shelters in all kinds of buildings, the heat insulation materials of fire grade A (non flammable) should be used.
2、对于其他场所,应采用低烟,低毒且燃烧性能不低于B1(难燃)级的保温材料。
2, for other places, low smoke, low toxicity and combustion properties should be used not less than B1 (refractory) grade insulation materials.
3、保温材料应采用不燃烧材料做仿护层,采用燃烧性能为B1级的保温材料时,防护层厚度不应小于
3. Thermal insulation materials should be made of non-combustible materials as imitative protective layer, and the thickness of protective layer should not be less than that of B1 thermal insulation materials with combustibility.
外保温系统防火要求
Fire protection requirements of external insulation system
采用外保温系统的建筑外墙,其保温材料应符合下列要求:
The external insulation system of building exterior walls should meet the following requirements:
1、与基层墙体、装饰层之间无空腔的建筑外墙外保温系统的保温材料应符合下列要求:
1. Insulation materials for building exterior wall external insulation system without cavity between the base wall and decorative layer should meet the following requirements:
(1) 住宅建筑
(1) residential buildings
建筑高度大于100m时,保温材料的燃烧性能应为A级。
When the building height is greater than 100m, the combustion property of the insulation material should be A-level.
建筑高度大于27m,但不大于100m时,保温材料的燃烧性能不应低于B1级。(据报道,格伦费尔大厦层高为24层,应该超过27m但不会超过100m,按照国内规范,外墙保温材料应该是难燃的)
When the building height is greater than 27m, but not greater than 100m, the combustion property of the insulation material should not be lower than the B1 grade. (It is reported that the height of Glenfel Tower is 24 stories, which should exceed 27m but not exceed 100m. According to the domestic standards, the insulation materials for exterior walls should be non-flammable.)
建筑高度不大于27m时,保温材料的燃烧性能不应低于B2(可燃)级。
When the building height is not greater than 27m, the combustion property of the insulation material should not be lower than that of B2 (combustible) grade.
(2)除住宅建筑和设置人员密集场所的建筑外,其他建筑
(2) other buildings except residential buildings and buildings with crowded places.
建筑高度大于50m时,保温材料的燃烧性能应为A级。
When the building height is greater than 50m, the combustion property of the insulation material should be A-level.
建筑高度大于24m,但不大于50m时,保温材料的燃烧性能不应低于B1级。
When the building height is greater than 24m, but not greater than 50m, the combustion property of the insulation material should not be lower than the B1 grade.
建筑高度不大于24m时,保温材料的燃烧性能不应低于B2级。
When the building height is not greater than 24m, the combustion property of the insulation material should not be lower than the B2 grade.
2、除设置人员密集场所的建筑外,与基层墙体、装饰层之间有空腔的建筑外墙外保温系统,其保温材料应符合下列要求:
2. In addition to the building of a densely populated place, the exterior wall insulation system of the building with a cavity between the base wall and the decorative layer shall be in accordance with the following requirements:
建筑高度大于24m时,保温材料的燃烧性能应为A级。
When the building height is greater than 24m, the combustion property of the insulation material should be A-level.
建筑高度不大于24m时,保温材料的燃烧性能不应低于B1级。
When the building height is not greater than 24m, the combustion property of the insulation material should not be lower than the B1 grade.
设置人员密集场所的建筑,其外墙外保温材料的燃烧性能应为A级。
The combustion performance of external wall insulation materials should be class A in buildings with crowded buildings.
3 、建筑外墙采用保温材料与两侧墙体构成无空腔复合保温结构时
3. Building exterior walls use insulation material and two sides of the wall to form a composite structure without cavity.
该结构体的耐火极限应符合有关技术规范的规定;当保温材料的燃烧性能为B1、B2级时,保温材料两侧的墙体应采用不燃材料且厚度均不应小于50mm。
The fire resistance of the structure should be in accordance with the relevant technical specifications. When the combustion performance of the thermal insulation material is B1, B2, the wall on both sides of the insulation material should be nonflammable and the thickness should not be less than 50mm.
以上就是关于A1级防火保温材料的介绍,希望能为你提供帮助!
The above is the introduction of A1 class fireproof thermal insulation materials, and I hope to help you!
