A guide to double glazing

Double glazing revolutionised the UK property and home renovation markets when it started to become popular in the 1970s and 80s. British homeowners quickly became impressed with the insulation benefits of this type of glasswork, and now you can barely walk down a street that does not have double glazed windows in the properties. However, how much do you really know about this popular type of window? Read on for a guide to double glazing.

What is double glazing and why is it so effective as a heat insulator?

It is common knowledge that double glazed windows and doors help to keep your home warm by insulating your property against cold drafts. However, how exactly does this work? Double glazing works by having two panes of glass with Argon gas installed in between. Argon gas is a safe and non-reactive gas that slows down the movement of heat passing through it, therefore ensuring that your home remains warmer for longer.

How can double glazing save you money?

Despite the initial expense of replacing your windows and doors, installing double glazing is an investment that is well worth the initial cost. This is because the insulating properties of double glazing help to increase the energy efficiency and thermal performance of your home. By insulating your property against drafts, your home is kept warmer for longer, without the need for keeping the central heating constantly running. This, therefore, helps to reduce your heating bills, which, in turn, enables you to save money in the long run.

Should you replace your double glazing?

Unless it is an older building that has not undergone extensive renovation work, a vast majority of properties in the UK now have double glazing. If your home already has double glazing, how do you know when you should replace your windows? Although double glazing is built to be robust, remember that it does not last forever and will eventually need to be replaced, approximately every twenty years or so. As double glazing technology has greatly advanced over the years, older examples will not work as efficiently as newer installations. Therefore, be vigilant for the signs that your double glazing is not working as efficiently and needs replacing.

How to Tell if Your Double Glazing Needs Replacing

So, how can you tell that your double glazing has failed and needs to be replaced? Below we outline some key elements that will pinpoint when you need to replace your double glazing.

An obvious sign is that your windows are letting in drafts and cold air, as prevention against drafts is a key component in double glazing. Drafts can affect your comfort in your home and can also contribute to higher energy bills as you try to counteract the cold air entering your home.
Condensation gathering on the inside facing glass suggests that there is a ventilation issue with your windows and condensation forming in the gap between the two panes demonstrates that your double glazing has failed entirely. Condensation can cause major problems to your windows, such as mould and damp, so it is vital that you get them replaced as soon as possible once you notice it.

There are noticeable cracks or chips in your window panes. This is one of the most obvious signs that you will be able to see every time you look out of the window. Some chips may be very small, and you may think you can ignore them and hope for the best. Some cracks may be large and can damage the structure of your window itself. Cracks and chips are a key sign of wear and tear, which you need to remedy.

You have difficulty opening and closing the windows. If you cannot open and close your windows smoothly, they need replacing. Fresh air is vital to keep healthy, but a window that opens correctly without having to use direct force is also essential in case of an emergency. If there is a fire on your property, having ways to escape is crucial, and your windows are one way to ensure everyone can leave home safely.

Replacing your double glazing is a vital way to keep your home cosy and comfortable to live in for all the family.
