, in summer they allow you to get fresh air and light into the home while in winter they protect you from the cold outdoors yet still provide what little light they can. Although all windows carry out this function, only the very best can be said to do it well enough for them to be considered efficient or useful. Old single glazed window units are extremely inefficient at keeping the cold out which can mean you pay far more each year to heat your home.
With double glazed windows you can start to claw back some of those costs that you spend each year on heating; they are highly efficient at keeping the cold out and keeping the heat in. The way that double glazing achieves this clever feat is through a very precise and modern assembly process which involves two panes of glass and some high tech sealing. This all contributes to a window that is both thicker and more insulating than a standard window. The gas or air between the two panes makes sure that the inside and outside temperatures never meet, this stops the build-up of condensation on the window and makes them more thermally efficient.
You can even go one step further with the manufacturing process of windows that allow them to become even more efficient at keeping the heat in. By creating technologically superior double glazing glass, it is possible to trap more heat in the home while letting the maximum possible amount of light in. This is done by making the glass panes out of very high quality sand which ensures that there is nothing at a microscopic level that blocks out the light. Furthermore, the addition of special coatings on the glass allows for light to be captured by the home but the heat from that light cannot pass back through the window. The coating effectively forms a mirror that reflects any warmth from light back into the home. Over time this can actually have the effect of heating your home.
When considering purchasing replacement windows for your home it is vital that you speak to your highly trained local double glazing installers who will be able to best advise you on what you need. The coated double glazing glass is only applicable for certain elevations of a home and they will be able to tell you what windows will work best for you.
