1、 Is polystyrene foam board flammable
In order to improve the indoor thermal insulation effect, many buildings will install polystyrene foam board on the exterior wall. Is polystyrene foam board flammable? Let's get to know it with Xiao Bian
Generally speaking, polystyrene foam board is easy to burn, and the smoke generated during combustion generally contains toxicity. Even if flame retardant is added to polystyrene foam board, its fire rating is not very high and can only reach Grade B. Therefore, when the building wall fires, polystyrene foam board will generally be burned.
2、 What are the skills for selecting exterior wall insulation board
1. Temperature environment
When selecting the external wall insulation board, the appropriate external wall insulation board material shall be selected for installation according to the climate temperature of the local city. If it is in the north, it will be cold in winter, so generally, materials with good thermal insulation effect should be selected, such as benzene plate. If you are in the south, you can choose to install mortar materials with insulation effect.
2. Thermal conductivity
When purchasing exterior wall insulation boards, you also need to consider the thermal conductivity of the materials themselves. If the thermal insulation performance of the materials is the same, you are recommended to purchase materials with lower thermal conductivity to make construction more convenient and take up less space.
3. Temperature
When purchasing exterior wall insulation boards, it is necessary to know whether the structure, quality and chemical properties of the materials are stable. If the chemical properties of the materials are unstable, it is easy to have problems in the later use process, so we suggest that you must choose to buy some materials with relatively stable chemical properties.
The above is the knowledge about the flammability of polystyrene foam board and the skills of purchasing exterior wall insulation board. I hope it can help you solve your doubts. Polystyrene foam board has good thermal insulation performance and is widely used. When you buy it, you must keep your eyes open and beware of being cheated.
