Our product range is one of the best performing on the market, taking full advantage of the increased thermal efficiency offered by its multiple chambers sash and outer frame, providing the most energy efficient windows available.
Made from 100% lead-free PVCu, incorporating advanced engineering and quality manufacturing with the highest security available.
Window Energy Ratings Certification
Our Window Energy Ratings certification scheme allows manufacturers to apply to use the energy rating label on their products (pictured right).
Conventional approaches (such as setting a glass or window U-value) simply assess how much energy a window loses. They do not take into account how much energy a window can gain.
The total energy flow in a window consists of three major components:
- Thermal transmittance (U-value)
- Solar factor (g-value)
- Air Leakage (L50)
The British Fenestration Ratings Council (BFRC) has devised a Window Ratings equation based on values for these components. The rating is expressed as a number. The rating is converted into a grade between A and G (with A being the most energy efficient).
