FAQs

how does double glazing work?

One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?

Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

How much money will I save with double glazing?

By replacing the single glazed windows in your home you stand to make savings of around £170 each year. It’s not just the financial gain that makes double glazing attractive though and you can also save up to 680kg of carbon emissions annually. Over 20 years this is a saving of around £3,400 and 13,600kg of CO2.

how much does double glazed windows cost?

Are you looking to replace your old window for a new double glazed window and wondering what it’s going to be the cost? Well, the double glazed windows market is a very competitive one in the UK with varying prices across the country. Therefore, if you shop around you’re most likely to find something that’ll fit your budget both products and quality wise.

As you would have expected, the more windows you required the more money you are going to spend. However, the cost per window is likely going to be lower depending on the number of windows you purchase. Several double glazed windows come with a 10 year warranty but it’s advisable to also obtain a solid workmanship warranty which provides coverage for any potential problems for a good period of time upon installation.

To determine the cost of double glazed windows, there are so many things to put into consideration that just the primary dimensions of the window itself. Other factors that works to decrease or increase the cost of the project includes the frames’ quality as well as the material used. For example hardwood can be quite high priced when compared to uPVC.

The number of opening windows within the frame can also play a huge role in the cost of the windows as well as the type of the glass. The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.

To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.
