Stone curtain wall energy saving and glass curtain wall energy saving practices are mainly different
Energy saving of stone curtain wall can be achieved by setting the insulation layer between the air layer between the curtain wall and the main structure, and the setting of the insulation material inside the curtain wall, and the combination of the two. Without having to set the insulation layer inside the main structure (inside the insulation), so as not to occupy the indoor space.
First, the insulation layer composite in the main structure of the outer surface, similar to the common external wall insulation practices. Insulation material can be extruded polystyrene board (XPS board), expanded polystyrene board (EPS board), semi-hard mineral (rock) cotton board, foam glass insulation board, composite silicate rigid insulation board, Benzene particles such as insulation mortar. The application thickness can be calculated according to the regional building energy efficiency requirements and the thermal conductivity of the material calculated by the heat transfer coefficient of the external wall. Insulation board and the main structure of the connection can be fixed or paste the mechanical anchor, or the combination of the two. Facial layer should also be, but can be simplified, the role of the protective layer is only moisture, anti-aging, and is conducive to fire.
Second, in the curtain wall and the main structure between the air layer set in the insulation material. In the horizontal and vertical direction of the keel separation of the case, the insulation material can be nailed in the keel layer. This approach can be added to the outer wall of an air layer, improve the wall thermal resistance.
?Third, the curtain wall inside the composite cleaning materials.
?Curtain wall insulation materials and stone, panel together, and even can be used stone insulation composite panels, but the insulation layer and the outer surface of the main structure of more than 50mm air layer, the air layer should be closed layer by layer. Insulation material can be used less dense extruded polystyrene board or expanded polystyrene board, or less density inorganic insulation board.
