By using a Fensa registered company they’ll issue this certificate, otherwise you’ll need the council to look at the new windows.
Double glazed windows are one of the most popular window options for home and property owners in the United Kingdom and reasonably so. They are able to offer a wide range of benefits to home owners which includes being energy efficient, reducing the build up of condensation on windows and black mould growth, significantly reducing background noise for a better relaxation or night rest, increasing the value of your property as well as adding to the aesthetic appeal of your home. So if you’ve decided to lay your hands on a double glazed window, you’d probably also like to know how much it’s going to cost. Well, providing a simple and accurate answer to the question of double glazing window cost is almost impossible as there are so many factors that influences the price including the materials and style.
Several suppliers usually provide the list of their double glazing windows on their websites, however these prices are only for basic off the shelf window and most often without the installation cost. Furthermore, if you require some special features to your double glazed window, then this will also tell on the total cost of the window.
So how much will a double glazing window cost? 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.
After fitting your new windows, your installer should take away and dispose of your old windows. If you want to keep them, just let your installer know before they start work. The UPVC frames are melted down and used on the unseen parts of new windows. Aluminium frames are re-smelted and wooden are broken down and used as chipboard.
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.
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.
It depends on a few factors whether a new double glazed window will look different to existing ones. If your existing windows are very old, perhaps 10 years or more, then it’s likely that there will be some small differences.
The first thing to remember is that your double glazing is exposed to the elements as soon as it’s installed. So over time, unless you’re very good at cleaning and maintaining your windows, they’re likely to look a bit dirty. Window frames that are south-facing may also become slightly discoloured from the sun, so if you install a new window right next to it you might notice a difference.
Also, there have been lots of technical advances in windows over the years. If your existing windows are significantly older, you might notice a difference in the handles on openers, and if your existing windows were installed before 2010 they might not have trickle vents, which is an extra strip on the inside of your window to keep air flowing through your home. While it’s not a legal requirement for replacement windows to have trickle vents if the original one didn’t, it’s a good idea to have them installed as they help prevent condensation and mould.
The only truly noticeably different elements to a new double glazed window compared with existing ones are likely to be on the inside, which might not be a problem for you if you only have one window in a room. However, if you know the brand of your existing windows, you can ask your window installer if they can source the same ones. Even if they’ve been updated slightly, the difference should be minimal.
