The overall performance of a window is dependent on the combined effect of frame and glazing components and the air-tightness of the finished window. Ratings maybe improved by decreasing thermal losses.

Decreasing thermal losses
- Type of Low-E glass: with its optimized balance of very low emissivity and high solar gain SGG PLANITHERM can improve the energy index for a given window
- Inert Gas filling: argon gas filling can improve the energy index for a given window compared to an air filled unit - Optimized cavity width: the optimum cavity width for an argon filled unit is 15mm (10mm with Krypto) - Warm edge spacer: Using SGG SWISSPACER can improve the energy index for a given window compared to standard aluminum spacer bars - Triple glazing: can further reduce glazing U values - Frame type: U values can be reduced with advanced materials and design
