Energy is expensive. That’s why it’s essential property owners take actions to ensure they get the most from every cent invested. If you’re wanting to keep your house warm and energy effective, particularly throughout winter, then you’ll wish to concentrate your efforts on the locations of your property most at risk.
Practically inevitably, windows form a weakness in a building’s outer shell. Through them, heat can quickly get away into the world outside, which in turn cools the residential or commercial property and requires more energy expense.
We can fight this issue in part with double glazing, or to a lesser degree, secondary glazing.
What is double glazing?
Double glazed windows are formed of 2 panes of glass, separated by a thin cavity. When the technology was first established, this space was filled with regular air. It was realised that dehydrating the interior of the window would avoid condensation from forming throughout cold spells, and improve performance. At that point makers started to drain the air entirely from their windows, filling the space instead with a vacuum.
Today double glazing is frequently filled with an inert gas, like argon, krypton or xenon. Of these, argon is the least effective– but it’s likewise the least costly– which suggests it’s a popular option with lots of homeowners.
Among the most substantial disadvantages of double glazing is the impact it has on the window’s appearance. The air (or absence of it) on the inside of the window will be made up differently to the air outside, therefore changes in atmospheric pressure will produce a difference in between the within and outside of the glass.
Because of these pressure differences, the glass can frequently bow inwards or outwards. This effect is specifically obvious when the sun is shining on the surface of the glass, and belongs to the reason why it can be hard to get the essential preparation approval to install double glazing in particular conservation areas. In such areas, homeowners should look for options.
What is secondary glazing?
Secondary glazing works through a comparable principle to double glazing, other than instead of both panes becoming part of the same window, secondary panes are connected to the existing single-paned window from the within. Due to the fact that there’s no seal, there’s no pressure distinction between the inside and beyond the window. What’s more, secondary glazing doesn’t need a whole window be replaced– it’ll merely slot behind the existing one.
While not as effective as double glazing, secondary glazing can be set up with minimum hassle to the back of an existing single-glazed window, and will yield considerable improvements in thermal performance. They’re therefore a popular service for owners of period property.
Secondary glazing likewise tends to be substantially cheaper than double glazing, so is perfect for house owners with a minimal spending plan.
Which should I choose– double glazing or secondary glazing?
Your choice will depend mostly on the sort of residential or commercial property you’re seeking to buy for, or your budget plan.
Frequently your choice will be determined for you by conservation laws or your budget plan.
Cost of double glazing vs. secondary glazing
Fitting secondary glazing is not surprisingly considerably cheaper than installing double glazing.
Typically, secondary glazing costs ₤ 97 per window, although this will naturally be affected by the size of the window.
The expense of a double glazed window depends upon the materials used and naturally, the size of the window; however the average expense for a double glazed window is around ₤ 500.
Secondary glazing and the environment
Both double glazing and secondary glazing are beneficial to the environment on account of the truth they will lower your energy usage in the home.
Replacing windows creates waste. Secondary glazing on the other hand, merely builds upon the existing window, which helps to minimise waste materials.
Installing secondary glazing
Another advantage to secondary glazing vs. double glazing is the ease of setup. You shouldn’t try to set up a double glazed window yourself (unless you’re really experienced with DIY), but it’s fairly basic to install secondary glazing– meaning you can cut down on costs.
