How frequently double-glazed windows need to be replaced is a question we’re often asked by customers. The answer is it depends, as there are numerous factors to take into consideration.
The general advice you’ll read is that PVC-U double-glazed windows need to be replaced about every 20 years. Aluminium windows typically last longer and will need to be replaced perhaps every 25 plus years. Having said that, these are just estimates as modern double glazing is likely to need replacing less frequently than double glazing installed from the 1980s and 1990s.
It’s worth noting that when we say 20 plus years, we’re talking about the lifespan of double-glazed windows. However, there are various factors when it comes to replacing double glazed windows more frequently. Let’s look at some of them.
How frequently should you replace double glazed windows when trends change?
Fashions change the whole time and double glazing is no exception. The earliest generations of double-glazed windows offered plenty of advantages
but were often practical rather than pretty.
Today’s double glazing – particularly aluminium double glazing – is available in a wealth of styles and colours. Double glazed windows can recreate heritage styles and they can also deliver cutting edge aesthetics for modern properties too.
It all means that if you want to change the look of your home, replacing your double glazing is a great way to do it.
How frequently should you replace double glazed windows when technology changes?
Original double glazing was much better than single glazing at keeping out cold and draughts. But the technology in today’s double-glazed windows is getting better and better all the time. Even windows installed a few years ago may be less efficient than windows manufactured today.
If you are looking for ways to cut your heating bills and reduce your carbon footprint, it’s worth looking at your double glazing. If you’re finding your home is draughtier than it used to be or it’s suffering from condensation, you should look at replacing your double glazing. If your furniture is fading in the sunlight, replacing your double glazing with new double glazing that uses glass with UV filters could be an option. In short, if your double glazing isn’t doing its job as well as it could, it might be time to consider replacing it.
Remember that aluminium double glazing needs to be replace less frequently
When it’s time to replace your double glazing, it’s important to consider the material you’re going to use. If you think back to the start of this blog you’ll remember that aluminium double glazing has a longer lifespan than UPVC.
It also delivers classic aesthetics that stand the test of time. It’s a good choice in terms of sustainability too. Modern aluminium windows offer excellent energy efficiency and they can also be recycled at the end of their life.
Quality of installation
You existing double glazing products are only as good as the original installation. Window and door installations are a considered investment and the installation needs to be first class to ensure years of trouble-free use. If your existing double glazing has been poorly fitted then it is probably time to get it replaced.
