The appearance of cement foam board has a direct impact on the market of insulation layers used. The application of floor heating and roof insulation is decreasing year by year. This cement foam board is completely fireproof, and it is a new type of exterior wall insulation material with low cost and high construction speed. , It is the first product of the external wall thermal insulation project in the future.

At present, the floor heating insulation layer in the foreign developed regions is the cement foam board used, and the application rate of the floor heating insulation layer of the cement foam board in China is also rising year by year. According to the momentum of development, it will be completely replaced in the future.

Comparison of cement foam boards and polystyrene foams:

First, the heat resistance comparison: Styrofoam's fatal weakness is the low heat resistance temperature, which begins to decompose at 74°C. When the temperature continues to increase, it will shrink by hot melt, resulting in polystyrene foam. Thermal decomposition deactivates insulation.

Foam cement board is cement inorganic material, heat resistance up to 800 °C, there is no high temperature decomposition, so the service life is longer, it will not cause insulation failure.

Second, environmental protection comparison: Cement foam board does not contain any toxic components, foaming agents and various additives are not volatile harmful substances, is conducive to the indoor environment, green, non-toxic harmless. Styrofoam releases styrene toxic gases due to pyrolysis. Therefore, the use of cement foamed panels is more environmentally friendly than the use of polystyrene foam.

Third, the strength of the pressure comparison: 160 ~ 200kg/m3 cement foam board compressive strength of 0.45 ~ 0.50MPa, polystyrene foam compressive strength, only 0.02 ~ 0.03MPa, cement foam board compression The effect is obviously much better than polystyrene foam.

Fourth, in the use of cost foam cement board has a more obvious price advantage.

Fifth, the construction speed: cement foam board can be laid directly, and polystyrene foam can not.
