Double glazing can improve your home in a number of ways. It helps prevent excessive heat loss, keeping your home warm in the winter, as well as helping it stay cool in the summer. It can also reduce outside noise, great for those who live in busy areas or close to a road.
Double glazing is constructed using two panes of glass, which are built into the frame with a gap in between. This gap is then filled with argon, a gas that works as an insulator and is denser than air. This means that when cold air hits the outer pane, the cold isn’t transferred to the inner pane, so your home is protected from the chill. It also cuts down on condensation, which is unpleasant and can make your home feel damp.
At Kayvex, our windows come with double glazing as standard and have extremely high energy saving ratings. If you want to cut down your energy bills even further, you can also upgrade to our triple glazing and super energy-efficient glazing. Double glazing is a great home investment, as you save money on your bills in the long term, and it can even increase your property’s value.
Another advantage of double glazing is that it helps make your home more secure. It’s already extremely difficult to get through our thick, high-quality frames, while the double glass panels are very hard to break without attracting attention. Kayvex design all our windows with toughened glass and security hinges for extra protection for your home.

Should I replace my double glazing?
Double glazing tends to have a lifespan of around 20-30 years, and as they get older they tend to become less efficient. If you’ve noticed that your windows don’t seem to be insulating your home as well as they once did, it might be worth replacing them.
If your double glazing is under 10 years old, however, it is probably a more cost-effective solution to have your windows repaired; at Kayvex, we offer a guarantee to repair your windows if they aren’t performing to the highest standard. If you’re looking to replace your windows completely and want the best thermal efficiency on the market, talk to one of advisors about triple glazing.
How much of a gap should double glazing have?
The reason why double glazing protects against noise and the outside weather is that it’s made up of two panes of glass with a gap in between. This gap is filled with a dense gas called argon, which slows the transmission of cold air or noise, so it doesn’t transfer to the inner pane.
The optimal gap is around 20mm in a 28mm thick unit, so all our windows are manufactured this way as standard. This gives you the best level of energy efficiency, so you save on your heating bills, as well as running an eco-friendlier home and helping the environment.
Can double glazing cut down on condensation?
Yes! Condensation is caused when the warm inside air hits the cold windowpane, causing the humidity in the air to condense and form droplets on the window. Double glazing is made from two panes of glass separated by a dense gas – we use argon. This gas stops heat transfer between the two panes of glass, so while the outside window pane might be freezing, the inner one should be at the ambient temperature of your home.
In some cases you may see a build-up of condensation on the outside of the glass because the cold can not transfer to the inner pane. This effect is perfectly normal and will clear once the temperature rises outside your home.
Can double glazing reduce noise?
Because of the way sound travels, it’s very easy for it to get through single glazing. If you live on a busy street, it’s worth investing in good double glazing, which has two panes of glass, with the gap filled by argon gas.
Adding argon gas to the gap means it’s harder for soundwaves to reach inside your home. The argon effectively dampens the sound, so it’s harder for the noise to reach your home. If you live in a noisy area and are craving some real peace and quiet, we offer Stadip Silence lamination on our windows, which cuts out noise drastically without the need for thick and heavy glass. Contact us today if you think this could be a good option for you.
How does double glazing work?
As the name implies, double glazing is made of two panes of glass rather than one. These panes are set in the same frame, with a gap between them, and the air is removed and replaced with argon gas. Argon is denser than air, which insulates your home from the outside weather, as well as dampening soundwaves, so your home is cosy and quiet.
Double glazing can improve your energy efficiency, so your home is warmer in the winter and cooler in the summer. This can also help you cut down on your energy bills.
How long do double glazed windows last?
Double glazed windows tend to last about 20-30 years, but the precise length of time they last will depend on a number of factors. To get the most out of your windows for as long as possible, you should make sure your windows have an A-rating for energy efficiency and that they are properly installed. You should also ensure you buy your frames from a quality manufacturer such as Kayvex, so they last for as long as possible.
If your windows feel noticeably cold to the touch inside, or you find yourself heating your home more in the winter, then your windows may be becoming less efficient.
