How does Double Glazing Help with Insulation?
The shocking amount of heat insulation that double glazing provides.
So many homes are still clinging on to their single glazed windows. We can understand that replacing your windows, which are such an important part of the exterior aesthetic of the house is a daunting prospect. However, when you recognise the amount of money you could be saving in heating costs, you’ll realise that it’s the right thing to do.
What Percentage of UK Households have double glazing?
The benefits of double glazing should have been well publicised by now, however, did you know that around 7% of households across the United Kingdom are yet to have double glazing? This is more than likely down to the fact that property owners are acutely unaware of what the implications of having the double glazing installed are. Not in the least the impact that it can have on their energy bills.
Whether you have just moved into a new home, or if you are looking to update your current glazing units or if you want a more effective way to save money on your bills, or even are looking at being more environmentally conscious, read this article to see how double glazing can be a great option.
How much heat is lost through windows?
Depending on the nature of the building, around 18 to 25 per cent of heat can be lost through the windows of a home if they are not energy efficient. In the wintertime, the inside of a building with double glazing is warmer, as draughts are excluded and less heat is radiated out of the home. At the same time, in the summer months, the double glazing stops it from getting too hot in the home by reflecting heat away. Double glazing can last anywhere between 10 and 50 years; depending on how well it has been installed, the quality of the windows, the location of the home and how well it has been cared for.
How is Double Glazing Made?
Quality double glazing should have a minimum of approximately 16mm spacing between the two glass panels. This cavity is usually filled with an inert gas such as argon, to reduce the transfer of heat. There should be non-metallic separators to keep these panes separate.
When it comes to the subject of reducing heat loss, there are some low-cost alternatives available, like vents, blinds and curtains. While they might seem cost-effective on the surface, they do not possess the same properties of insulation as double glazing. Heat loss will occur twice as fast as it does through double glazing. You will also be spending more money on repairs and replacements - rather than just investing in double glazing in the first place.
When it comes to quantifiable monetary savings, category b rated double glazing is estimated to save as much as £110 to 140 per year in costs of heating a regular detached home. For 10 years, this amounts to £1,100-£2,800. Now, wouldn’t you rather have that for improving your home further? As such, it saves you money in the long run and keeps you warm. Now if you were going to invest in category A or even A+ rated windows then you are going to save even more!
