HarbourView Top Rolling Multi-Fold Door
HarbourView Top Rolling Multi-Fold Door
The system is ideally suited for shopping centres, offices, showrooms, and commercial buildings. It is also widely used in high end residential developments and apartments.
As with all of the HarbourView systems, the top rolling multi-fold door 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.
