What material is used for external wall insulation?

In architecture, bad weather has a great influence on the external wall, especially the heat loss, which accounts for a very large share. Therefore, in order to protect the service life of the main structure and make users more comfortable, thermal insulation materials will be installed on the external wall. So, what is the material for external wall insulation? What elements should be mastered when purchasing? Let's have a brief look with Bian Xiao.

1. What materials are used for external wall insulation?

External wall insulation materials include phenolic resin foam, external wall insulation grid cloth, phenolic resin foam, cement-based foam, rock wool board, ceramic insulation board, perlite and other slurries, expanded polystyrene board, extruded polystyrene board, rubber powder polystyrene particle insulation slurry, polyurethane foam material and so on.

Second, what elements should be mastered in purchasing external wall insulation materials?

1, the external wall insulation materials should be selected according to the actual temperature and climate environment, especially in the north where the temperature difference is large. It's very cold when it's cold, and very hot when it's hot, so we should choose external wall insulation materials with good heat insulation effect, such as benzene board.

2. When selecting external wall insulation materials, if the insulation effect is similar, materials with low thermal conductivity should be selected, because materials with low thermal conductivity can not only meet the design conditions, but also facilitate transportation and construction.

3. External wall thermal insulation materials require high performance, including stability, mechanical strength, flame retardancy, water absorption and constructability. If consumers are inexperienced, it is best to compare several kinds and choose products with high cost performance.

4. Service life is a problem that must be considered when purchasing exterior wall insulation materials, because it needs to withstand the constant changes of seasons and the influence of weather freezing and thawing cycles, and long-term use will lead to the decline of physical properties, so choose the one with good aging resistance.

Editor's summary: What materials are used for exterior wall insulation and what elements should be mastered when purchasing exterior wall insulation materials? That's all. I hope it helps you. If you want to know more, please follow Qijia. com。
