When you consider that a single pane of glass can lose almost ten times as much heat as the same area of insulated wall, it is worth taking some simple steps to reduce heat loss through your windows to make your home more comfortable and reduce your heating costs.
Size and orientation
The size and orientation of your windows will affect the amount of sunlight entering your home. West, east and north-facing windows tend to be exposed to sunlight, while south-facing windows receive almost no direct sunlight. If you are planning a renovation consider orienting your living areas and windows to the north, and rooms where you spend less time to the south. This will take advantage of the winter sun, keeping these rooms warm, light and bright.
Frames and glazing treatments
The strength of window frames, together with the glazing component, can greatly affect the energy efficiency of windows. The most energy efficient window frames are made from materials that won't transfer heat and cold, such as timber, uPVC or combination frames.
