Application of house wrap in metal roofing

Solution for profiled steel sheet roofing

1. In hot summer and cold winter (hot summer and warm winter) areas, PANZHU integrated thermal insulation and waterproof membrane (heat insulation reflective foil) is installed outside the roof insulation layer to prevent rainwater from invading the wall structure. When indoor centralized refrigeration is carried out in summer, it effectively prevents outdoor high-temperature and high-pressure water vapor from infiltrating into the structure to form condensation, and PANZHU is installed inside the insulation layer to permeate vapor. The waterproof cushion (waterproof and vapor permeable membrane) is used to discharge residual moisture in the insulation layer and protect the thermal performance of the insulation layer.

PANZHU thermal insulation waterproofing integrated coil provides excellent heat insulation effect and effectively reduces building energy consumption.

2. In cold (cold) areas, PANZHU thermal insulation and waterproof integrated roll material (heat insulation reflective foil) is installed inside the roof insulation layer. In winter, when indoor heating, it can effectively prevent the high temperature and high pressure water vapor from discharging into the insulation layer to form condensation and protect the thermal performance of the insulation layer. PANZHU thermal insulation waterproofing integrated coil provides extra insulation effect and effectively reduces building energy consumption.

The PANZHU vapor permeable and waterproof cushion (waterproof and vapor permeable film) is set on the outer side of the insulation layer, which can effectively discharge the residual vapor of the insulation layer and prevent rainwater from invading the wall structure.

3. For buildings with high indoor temperature and humidity in hot summer and cold winter (hot summer and warm winter) areas, such as swimming pools, it is suggested that PANZHU integrated thermal insulation and waterproof coil (heat insulation reflective foil) be used both inside and outside the roof insulation layer to prevent the indoor high temperature and humidity water vapor from entering the insulation layer from cold condensation. The two-layer insulation and waterproofing integrated membrane can form the inner liner structure of the building thermos bottle, which has the incomparable thermal insulation and thermal insulation effect of any thermal insulation material, and can significantly reduce the building energy consumption.
