Improved Planitherm Total Sets New Standard for WERS

Saint-Gobain Glass has improved the Window Energy Rating (WERs) performance of its flagship SGG PLANITHERM TOTAL low-emissivity glass thanks to successful R&D and investment at its UK coating facility.

The solar factor (g-value) of SGG PLANITHERM TOTAL has been increased by 2% to 0.66 for standard windows (0.71 with SGG DIAMANT low-iron glass outer pane) whilst maintaining the same low U-value of 1.2 W/m2.K, further optimising the balance between heat loss and solar heat gain. This development signifies a turning point for the market, making cost effective energy saving windows easier to achieve than ever.
