there is no essential change in the constraints between the materials. There is no argument that the mortar constraint on EPS is better than the constraint effect on XPS, and many engineering examples also confirm this effect. Extrusion insulation board industry status quo, Xiaobian temporarily analyzed here, I hope you understand the extruded insulation board is helpful, if you want to know more extruded insulation board knowledge, please continue to pay attention to every home renovation network.What are the performance characteristics of cement foam board? Cement foam board with high fire resistance, high thermal insulation, non-toxic harmless, long life, good water resistance, good interface, energy saving and environmental protection. Cement foam board details please see below. 1, high fire resistance Cement foam board is A1 grade fireproof materials, has good fire resistance, fire resistance reached 1000 ?? above, fully meet the requirements of the fire barrier. 2, high thermal insulation Cement foam board closed hole rate of 95%, high closed-cell rate to reduce convective heat transfer is a prerequisite for high thermal insulation. Thermal insulation board with a special board thermal conductivity and
