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.
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.
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.
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.

Accidents happen, and sometimes windows get broken. And that will lead to you wanting to replace just the glass in your window, rather than the whole frame. Also, as windows get older they can mist up on the inside, which means that the unit has ‘blown’ - so you’ll also need to replace the glass. But how much is it to replace the glass in a window? Luckily, if the frame of your window is in good condition, there’s no need to replace it, and this will reduce the cost. For an installer to fit a new pane of glass in a single glazed window, the average cost is £100, while a replacement double glazed sealed unit will cost an average of £110. Of course, as this is an average, if your window is very large you may spend more, and if your window is very small the price may be less. That's why it’s important to get a range of quotes so you can compare costs and get the best price. If you’re good at DIY, you may feel confident enough to have a go at replacing the glass in your window yourself. In that case, the cost of sealed unit and any other materials you need will cost an average of £57. It’s a significant saving, and if you think you can do it, then give it a try. However, if you’re in any way unsure, it’s best to leave it to the professionals. A window installer will be able to replace the glass in your window in less than an hour. Even though it costs more for a professional to do it, if you get it wrong and have to start over it will cost you more in the long run.
Are you about to purchase a double glazed unit and wondering how to go about the replacement project? If yes, then you’re at the right place. Firstly, it’s advisable to hire the services of a reliable professional who can guarantee the best results for help especially if you lack proper training and experience in the field. However, we’ve put together this step by step guide to provide you with a detailed information about the double glazed unit replacement process. Let’s get started!
The tools and materials you require for the project includes tape measure, hammers, nail punch, scraper, spacing blocks, non-hardening butyl putty, high-security glazing tape rolls and beading tacks.
• Work out the glass size required. Simply use the tape measure to measure from frame edge to frame edge while also taking note of the thickness.
• When about to order, inform the glass merchant that the measurement provided are frame-tight. This will make him reduce the dimension a little bit, mostly by 5mm for clearance.
• Remove the beading and ensure to support the glass while doing so. If the glass units are fitted in wooden windows, you may need to cut the putty-based compound they’re normally sealed with to remove the glass.
• Lay out the beading in the window’s shape to make for easier refitting later on.
• If you’re working on wooden frames, wipe out all traces of excess installation compound using a scraper and clean the rebate with a soft brush.
• Trial fit the double glazed windows to ensure they’d slide into the frame without being forced.
• Plastic frame windows are usually in between a pair of gaskets, you should replace this with a hight security glazing tape. While for a wooden frame, simply apply strips of flexible non-setting butyl putty or high-security glazing tape on either sides of the glass.
• Install and centralize the glass in the frame.
• Press the nail wooden beading or plastic beading back into place.
