石材幕墙的节能可以通过在幕墙板与主体结构之间的空气间层中设置保温层,以及在幕墙内部设置保温材料来实现,也可采用两者的组合做法。而无须将保温层设置在主体结构内侧(内保温),以免占用室内空间。将保温层复合在主体结构的外表面上,类同于普通外墙外保温的做法。保温材料可采用挤塑聚苯板(XPS板)、膨胀聚苯板(EPS板)、半硬质矿(岩)棉板、泡沫玻璃保温板、复合硅酸盐硬质保温板、胶粉聚苯颗粒保温砂浆等。其应用厚度可根据地区的建筑节能要求和材 The energy saving of the stone curtain wall can be achieved by providing a thermal insulation layer in the air space between the curtain wall panel and the main structure and the insulation material inside the curtain wall, or a combination of the two can be adopted. Without the need to set the insulation layer inside the main structure (within the insulation), so as not to occupy the interior space. The insulation layer composite structure on the outer surface of the main body, similar to ordinary external insulation practices. Insulation materials can be extruded polystyrene board (XPS board), expanded polystyrene board (EPS board), semi-hard rock (rock) cotton, foam glass insulation board, composite silicate rigid insulation board, Benzene particles insulation mortar and so on. Its application thickness according to the building energy efficiency requirements and materials
