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.

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.

how to fit a double glazed window?

Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.

• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.

• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.

• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.

• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.

• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.

• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.

• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.

Will double glazing increase my property’s value?

These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.
