Construction of dry-fasten stone on external wall

Construction of dry-fasten stone on external wall
It is used for project in Northern China which have cold weather.

Project adopts New Type of dry-fasten stone on external wallwithout welding. light weight, high strength, fast installation and high cost performance. Super-low K value is a great selling point to make builders in various regions to select this material.

Thermotechnical Comparison Table:

Suppose dry-fasten stone built on 250mm reinforced concrete wall body

Item	Traditional stone curtain wall	Curtain wall made of New Type of stone dry-fasten without weld technologic
Wall thickness	250mm	250mm
Thermal resistance of reinforced concrete wall	0.144 m²·K/W	0.144 m²·K/W
Thermal resistance of slabstone	0.007 m2·K/W (25mm thick)	1.28 m2·K/W (integration of decoration and heat insulation, 47mm thick)
Thermal resistance of air layer (enclosed air layer 80mm)	0.18 m²·K/W (without aluminum foil)	0.71 m²·K/W (two-side aluminum foil)
Thermal resistance of external surface	Winter:0.04 m²·K/W Summer:0.05 m²·K/W	Winter:0.04 m²·K/W Summer:0.05 m²·K/W
Thermal resistance of internal surface	0.11 m²·K/W	0.11 m²·K/W
Heat transfer coefficient (K value)	Winter:2.04 W/(m²·K) Summer:2.00 W/(m²·K)	Winter:0.44 W/(m²·K) Summer:0.43 W/(m²·K)
Heat bridge	Great heat transfer coefficient; heat bridge can not solve; K value often higher than design calculation in actual project	Broken heat bridge; actual project conforms to design calculation
