About CityView Double Hung Window
With a modern, slimeline design, the cityview double hung window provides maximum ventilation and unobstructed views.
It also comes with a range of sub head and also features a finger groove grip for ease of operation.
As with all of the CityView systems, the double hung window has been tested and exceeds Australian Standard AS2047.
WERS Ratings
The Window Energy Rating Scheme (WERS) is accredited by the AFRC – which means that WERS ratings are compliant with the NCC.
Reports are prescribed both the window performance for total window U Value (Uw) and total window Solar Heat Gain Coefficient (SHGCw).
U-value
U-value measures how well a product prevents heat from escaping.
It is a measure of the rate of non-solar heat loss or gain through a material or assembly.
U-value ratings generally fall between 2.0-10.0 W/m2.K for Australian products. The lower the U-value, the greater a window’s resistance to heat and cold flow and the better its insulating value.
Solar Heat Gain Co-efficient (SHGC)
SHGC measures how well a product blocks heat caused by sunlight. SHGC is expressed as a number between 0 and 1. The lower a window’s SHGC, the less solar heat it transmits.
