WERS
The Window Energy Rating Scheme (WERS) is accredited by the Australian Fenestration Rating Council (AFRC) and is compliant with the National Construction Code (NCC).
Reports are prescribed both for the total window performance U-value (Uw) and total window Solar Heat Gain Coefficient (SHGC).
Reports are prescribed both for the total window performance U-value (Uw) and total window Solar Heat Gain Coefficient (SHGC).
UW
UW measures heat conductivity, calculating the rate of non-solar heat loss or gain through the total window system (glass, framing, seals).
The Uw helps indicate how well a window or door rejects heat during summer and retains heat during winter. A lower number indicates better performance.
The Uw helps indicate how well a window or door rejects heat during summer and retains heat during winter. A lower number indicates better performance.
SHGC
SHGC measures the total window systems ability to block heat transfer through direct sunlight. A lower number indicates better blocking performance; however a high number might be appropriate in cooler climates or with specific building orientations.
