There is no better option than double glazed windows when you are looking for thermal insulation and noise reduction. Not only are they being used in new home construction, but people are also opting to replace their old windows with double glazed ones. But, what exactly is double glazing? A double glazed window refers to a window frame that comprises of two panes of glass rather than just one. An air pocket typically separates the two panes, which can improve the thermal insulation of the windows drastically and also offer some acoustic insulation.
You can also achieve double glazing by choosing to retrofit uPVC windows over the existing ones. There is also a third method, which involves the application of noise dampening and UV blocking plastic sheeting onto the windows directly. Technically, this last method doesn’t exactly classify as double glazing and can only offer modest improvement, but it is the cheapest option available and can be regarded as a useful DIY project whereas retrofitting and installation of new windows is best left to professional installers or those who have exceptional DIY skills. However, you should also remember that double glazed windows are priced higher than standard windows.
While the higher cost is justified when you are building a new house, the window fitters guide to installing double glazing indicates it can only be justified for window replacement when the timber frame has become rotted. In this situation, it is viable to consider putting in double glazed windows. Another scenario where you can consider putting in double glazed windows is when a large window is not dampening external noise or is allowing too much heat transference. As mentioned before, the noise reduction and thermal insulation properties of double glazed windows come from the space between the panes. The more the gap between the window panes, the better the insulation, especially in terms of noise.
The gap between the panes in standard double glazed windows is 6mm. As far as retrofitted uPVC windows are concerned, they come with their own removable fastening systems and discreet frames. They are placed at a distance of about 100mm from the existing windows, which allows them to make a major difference in the acoustics of a room. According to experts, this can reduce the noise level by 75%. When dealing with problem areas such as next to schools or busy roads, you can choose to combine uPVC retrofit windows with double glazed ones.
You can also give the windows some UV blocking or tinting if there is a problem of direct sunlight. When you are in the market for double glazed windows, you can consider getting ones that have low-e glass on the outer pane. Also, experts state that you will not be able to enjoy the acoustic and thermal efficiency of double glazed windows if they are not installed properly. Therefore, the best way to get the most out of your investment is to hire a professional to handle the installation instead of doing it yourself.
