Its material is hard, and its service life can reach decades or even hundreds of years under general conditions. The selection of thermal insulation decorative board should be considered from the color system, pattern, pore water absorption, hardness, etc. Let's take a look at how to judge the quality of thermal insulation decorative board.

1、在选购保温装饰板时可以用手敲击石材检验坚实度，敲保温装饰板表面，听其声响、感觉触碰，若是品质坚固的石材则会发出清脆坚实的声音感觉，以避免挑到内部存在的轻微裂缝石材。

When choosing the thermal insulation decorative board, you can tap the stone to check the firmness, tap the surface of the thermal insulation decorative board, listen to the sound and feel the touch.
