Things You Should Know About Double Glazed Windows

Updated: Feb 4, 2021

As the winter days draw in and the nights get darker and longer, you’re probably starting to brainstorm some ideas about insulating your home to perfection. Not everyone is lucky enough to have a wood burner to cosy up in front of or an open fireplace, and if you have a big house and family to warm up, then heating bills can burn so many holes in your wallet. One step you can take control of the environment and energy consumption around your home is by installing double glazed windows and doors in your home.

There are countless types of windows with double glazing. While you can find ones with contemporary design and wooden frames, you can also find many that are made with durable and hassle-free uPVC frames. While installing these windows can fall under the chart of DIY projects, it will be better to get professional help as this will also affect the longevity of the windows you are installing in your home.

Here we will tell you more about double glazed windows and help you examine what they actually are, the available options, their main purpose, and the many benefits of installing them in your home.

History first…

Double glazing dates back pretty much further than you might think; after originating in Victorian Scotland, it became popular in America during the 1940s and 50s, before entering the United Kingdom in the mid-1960s. From the 1980s onwards, double glazed windows were the standard in most UK new-build homes.

What is double glazing?

Double glazed windows are made up of two panes of glass, separated by a gap of around 16mm filled with a layer of inert gases like argon, krypton, or xenon or a vacuum of air. They are also equipped with primary and secondary rubber seals, which are designed to stop heat from escaping the building. Glass is a good conductor of heat, so with single glazed windows, heat gets escaped easily. The gas or air space in between panes of double glazed windows is a poor conductor of heat, so this helps to prevent warm air from escaping. Most double glazed windows are engineered from uPVC frames and with low-emissivity (Low-E) glass.

The primary purpose of double glazed windows?

The primary purpose of double glazed windows is insulation for both noise and heat. Double glazing was originally designed to insulate properties and bring energy efficiency into the homes. Double glazing is also very effective at cancelling outside noise; the vacuum or gas in between the glass panes absorbs sound, and the added pane acts as a buffer, meaning excess noise won’t cause disturbance to those who are inside. Most modern apartment buildings and offices now have double glazed windows, especially if they’re built in the city centre or busy areas.

Having two glass panes instead of one is naturally a lot stronger. This adds an extra layer of security to your building. The double-layer technology also prevents the appearance of condensation by maintaining temperatures, as air pocket ensures that the air inside the house doesn’t come in contact with the air outside. Condensation can cause musty smells and damps if not dealt with, which can cause harm to your property. But with double glazing, there’s a much less risk of it happening.

Benefits of double glazed windows

Here are many sensible reasons why you should choose double glazed windows for your home, which we will explore below in detail.

Energy efficiency and cost-efficiency

Double glazing saves you money by keeping your home’s temperature maintained with less energy output required – which helps reduce your energy bills. The Low-E glass is very energy efficient, and the thin coating on it reflects heat back to its source – keeping your home warm in winters and cool in summers.


Adding an extra layer means there is twice as much to smash - not to mention the windows are extremely strong - which is a powerful preventive against burglars. It’s also almost impossible to break in through double glazed windows without making a lot of noise, so you can be relaxed that your home, family, and possessions are well protected.

Practical and stylish

Double glazed windows are easy to maintain and clean, and more durable than those single-paned windows so their curb appeal last longer. The uPVC and aluminium frames are environmentally friendly as they are both long-lasting and can be recycled after surviving wear and tear for long.

Increase property value

If you have plans to sell your home in the next 5 to 10 years, the addition of double glazed windows can add substantial value to your property. Many real estate agents agree that newly installed double glazed windows are a good selling point for modern homes.
