Window Installer FAQs

How much could I save on my energy bills if I install double glazing?

As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.

What is double glazing?

If a window is double glazed, it has two panes of glass that have a space between them containing argon gas. The gas works as an insulator, keeping heat inside the house as well as reducing noise. It also strengthens the window.

how long does double glazing last?

Just like every other thing in your house, your double glazed windows have an expected lifespan attached to it as it gradually becomes less functional and less efficient over time. Although there are actually top quality windows which are able to last a very long time, but the fact still remains that nothing can stand the test of time or last forever. Even the best quality double glazed windows will eventually need to be replaced at some point. So exactly how long do double glazing windows last before need a replacement?

To make it brief, most double glazing window units are typically expected to last an average of 20 years. This number of years can, however, vary within the range of 10 to 35 years based on the several factors such as the type, quality of materials as well as installation and where the windows are located.

The reason for the depreciation in double glazing windows is, over time, the windows may be subjected to some wear, tear as well as all kinds of minor damages which includes gas filled insulated glazing unit slowly and gradually leaking. According to the Centre for Sustainable Energy, the evaporation of 25 percent of gas will ultimately minimize the windows’ thermal performance. And when this occurs, fitting a secondary glazing measure or replacing the windows should be put into consideration.

Another factor leading to the gradual depreciation in double glazing windows over time has to do with condensation. When the window collects between the layers of glass due to the failure of the seal of the perimeter and the saturation of the desiccant, can only be solved by IGU replacement.

And finally, the ravages of time also has a way of taking its toll on double glazing windows. This can happen in so many ways such that the window becomes a lot less efficient and later needing to be replaced.

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.

Why aluminium windows?

Aluminium windows have a range of benefits that make them a great alternative to uPVC windows. Developments in technology have meant that modern aluminium windows now have the same energy efficiency levels as uPVC. Plus, their strength and flexibility make them a more attractive choice to many homeowners, particularly for more modern buildings.

Aluminium frames are typically much thinner than uPVC frames, allowing more light in and wider views. The metal can also be moulded to suit custom shapes, making it ideal for unusually shaped windows. Aluminium windows are available in lots of different colours, so can be designed to suit a wide range of interiors and exteriors.

What happens if I have problems with my new windows?

Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.

Are A-rated windows worthwhile?

On the grand scale of things there isn’t a huge difference between B-rated windows and A-rated windows. Consumer watchdog Which? have calculated an extra 6.5% would be saved on energy bills with A rather than B rated panes. Be aware that A rated windows are slightly more expensive, however.
