Introduction of rock wool external insulation system
The "rock wool board" external wall insulation system mainly uses the hydrophobic rock wool board produced by the swing method as the insulation layer material, which is connected and fixed on the foundation wall through the combination of adhesive nails, and is composed of plastering mortar and reinforced glass fiber mesh and decorative mortar finish layer or paint, forming a non-combustible building energy-saving insulation system
Which is better, sound-absorbing material or sound-insulating material?
Sound insulation materials: usually materials without gaps, such as steel, wood, gypsum board, brick wall, etc. Sound insulation depends on the surface density of the material. The higher the surface density, the better the sound insulation effect. Therefore, compared with the thickness of the board, the sound insulation effect of the steel plate is much better than that of the board.
