Yorkshire Windows

All properties lose heat through their windows. But energy-efficient glazing keeps your home warmer and quieter as well as reducing your energy bills.

How energy-efficient glazing works

Double-glazed windows have two sheets of glass with a gap between them, to create an insulating barrier that keeps heat in. This is sometimes filled with gas. Triple-glazed windows have three sheets of glass, but aren't always better than double-glazed windows.

Energy-efficient windows must also deal with:

* how well they stop heat from passing through the window

* how much sunlight travels through the glass

* how little air can leak in or out around the window

Energy rating

Some window and door manufacturers show the energy efficiency of their products using an energy rating scheme from A to G - like the one used for appliances such as fridges. The whole window (the frame and the glass) is assessed on its efficiency at retaining heat. The scheme is run by the British Fenestration Rating Council (BFRC), and you can find more information on the BFRC website. Our products go one stage further. We have achieved a Window Energy Rating (WER) for our products which has been verified by The British Standards Institute giving us our very own kitemark. You can be sure that when we say our products are "A" rated.... they really are!

Window Energy Rating

Low Emissivity Glass

Vital to the energy efficiency of the Window is the glass itself. All our "A" rated windows featured Planitherm Glass.

Planitherm products use a special coating to reflect heat from domestic heat sources back into the room, rather than allowing it to escape through the windows. At the same time, this coating allows free heat and light from the sun to pass through the glass, warming the room and further contributing to the energy efficiency of the windows and helping to reduce your energy bills.
