An awful lot of heat is lost through the windows of a house, not only making the occupants cold, but costing them money as the heating is turned up to compensate. It is far better to address the heat loss problem by ensuring that a home’s windows are as energy efficient as possible.
There are multiple benefits to installing energy efficient windows. Firstly, there is the cost saving. Replacing single glazed windows with double glazed ones could save approximately £170 per year. Yes, there will be an initial installation cost, but this should be recouped in a few years as the energy bills decrease.
As a knock-on effect, there will be fewer cold spots or draughts within the home. All this will mean that staying indoors during the winter months will be more comfortable than ever. No more chilly nights swaddled up to the neck in thick woollen jumpers. Energy efficient windows should also mean that condensation does not build up as much on the inside.
Double-glazing also means that outside noise is reduced, especially useful if the home is situated on a main road that has a lot of traffic, or is the main thoroughfare to a busy public building, such as a school.
If all this is not reason enough to switch to energy efficient windows, just consider how much better for the environment they are. By using less energy to heat the home, and therefore less of the planet’s diminishing fossil fuels, the home will produce less carbon dioxide, perhaps as much as 680kg per year.
Types of window
There are plenty of different types of window from which to choose, each with their advantages and drawbacks. Metal or aluminium frames, for example, are great conductors, which for windows, means that they will lose heat very quickly. Wood is quite a good insulator, but wooden frames will absorb moisture, and either shrink or expand according to the weather. Which leaves either fibreglass or vinyl window frames. Fibreglass frames have cavities within their framework that can be filled with an insulating material. The same goes for vinyl, but these also have the advantage of being resistant to sunlight and moisture.
Once a framing material has been decided upon, it is time to establish what type of double-glazing glass is best. Some window glass has been treated with a special tint that absorbs incoming solar radiation to heat the room, and changes the colour of the glass slightly. Other glass has a low-emissivity coating which controls the heat loss through the window. They can be more expensive than other types of special glass, but they have been known to reduce energy loss by as much as 50%.
Windows dressings to prevent heat loss
If changing the windows is too expensive an option, reconsider the way the windows are dressed. Window shutters offer benefits during both the summer and winter months, as they can prevent heat gain and loss. If shutters, like the ones found at www.kellyhoppenshutters.com, are fixed properly, they provide an insulating air space between the window and the shutter. During winter, drawing the curtains can reduce a room’s heat loss by 10%, but they need to be hung so they touch the window frame, forming a barrier.
