Windows can transform a room by allowing natural light in, however traditionally they have been a room's main point of heat loss.
Windows are an important factor in achieving comfort within a home as they can work in the same way as the insulation to stop heat
entering or leaving the home. There are three main classes of performance adaptions to windows:
-
Double-glazed windows have a sealed air space in between the glazing layers which acts like insulation allowing less heat out in winter and less heat in during summer.
-
Secondary glazing solutions can transform an ordinary single-glazed window into a double-glazed window.
-
Improved glasses such as low-e glass and advanced window frames can improve the insulating aspect of windows.
The performance of these windows is measured by a Window Energy Rating System (WERS). This allows you to select the best performing window for your climate zone.
