The higher the density of the foam board, the better the insulation?
Single-row fastener type steel pipe scaffold for decoration works in the construction of small horizontal bar spacing should be the number of mm...................................................
Distinguish its dry density, and burn performance, the most direct way is to burn with a lighter!
027W / (m · K )], Low water absorption, water vapor permeability coefficient is small and so on In the long-term high humidity or immersion environment, XPS can still maintain its excellent thermal insulation properties Figure 2-1 shows the thermal resistance of various commonly used insulation materials at 70% relative humidity for two years Display XPS board is the only two years after the thermal resistance retention rate remained at 80% or more of the insulation material In addition, XPS board also has a good resistance to freeze-thaw performance After a thousand freeze-thaw cycles, the compression performance retention rate of the XPS plate was more than 92% XPS board also has good anti-compression creep performance 70% relative humidity of the material under the thermal resistance retention rate
