When you have new windows installed, you don’t expect to need to replace them within a few years, in fact, you hope to get at least 30 years out of them. This is why it is important to make the right decision when choosing between double or triple glazing for your windows.

It is also important to look after your windows efficiently if you want them to last you. This means cleaning them correctly every now and then. Throughout this blog, we will be exploring the differences between double and triple-glazed windows and which type is best suited for you. Read on to learn more!

What is The Difference Between Double And Triple Glazing?

Double glazing is a sealed glazed unit which has two panes of glass. Triple-glazed windows, however, have three panes of glass.

The panes of glass used in each unit do not need to be identical - in fact, by using a range of glass types you can use windows for different requirements and environments.

Although double and triple-glazed windows use the same type of glass, the main difference between the two is the higher levels of efficiency and improved performance. Some of the main differences between the two are:


Less Noise

Although both double and triple-glazed windows offer effective noise reduction, triple glazing is more likely to prevent external noise compared to double-glazing. This is because triple-glazed windows offer that extra glass pane (hence the name).

If you live in a noisy area- for example, near a train station, then you are best considering triple-glazed windows. However, if you are on a budget, then double-glazed windows are a suitable option for you.


Heat Retention

Double-glazed windows work by preventing any hot air from escaping through air gaps. However, triple-glazed windows are a lot more effective in this area as they offer that extra pane of glass.

Windows typically account for around 10 percent of total heat loss and around two-thirds of this is down to radiation through glazing. Another factor of heat loss throughout the house can be air leakage from windows with poor insulation.



Laminated glass has a PVB layer of thin plastic between the glass panes. If this was to be laminated the glass will break. If the glass was to break, the glass is fused to the PVB lawyer and stays in place to prevent the glass from shattering.

Triple glazing has another pane of glass which makes it a lot more durable compared to standard double glazing.


Double Glazing Vs Triple Glazing

Double-glazing has a lower energy rating compared to triple-glazed windows. Double-glazed windows are relatively cheaper compared to triple-glazed windows, this is due to the insulation features double-glazed windows offer.

There are many advantages to double glazing such as it is energy efficient, cost-effective and offers effective noise reduction. Triple-glazed windows, on the other hand, are energy efficient, provide reduced condensation and increased security.

Double-glazed windows are more likely to produce a greater amount of energy loss through window panes and frames. Whereas triple-glazed windows maintain heat better as it has an extra window pane.

Both types of windows have the ability to retain heat, reduce noise and increase the security of your home. If you have single-glazed windows throughout your home, then you will be best considering either double or triple-glazed windows.

Triple glazing is recommended for any cold rooms and this is due to the insulation and energy-efficient features they offer. If you are someone who lives in an area with extreme weather, then you are also best investing in triple-glazed windows.
We recommend double-glazing for rooms that are not too cold or if you live in an area that doesn't experience extreme weather conditions.

Which is Best, Double or Triple Glazed Windows?

If you are looking for a window that insulates well, lowers your energy bills and keeps your home warm during the winter, then triple-glazed windows are the solution for you. Improved heat retention is useful if you're looking to replace single or old, double-glazed windows.

Triple-glazed windows are harder to break compared to double-glazing this is due to the extra glass pane. This, therefore, increases the security of your home, making it harder for intruders to enter your home.

Overall both triple and double-glazed windows have pros and cons and the type of window you purchase depends on personal preference and budget. For example, if you want a window that is cost-effective but still offers some insulation properties, then double-glazed windows are the ideal solution.

However, if you don’t have a budget and want a window that offers high-quality insulation properties, then you are best investing in a triple-glazed window. Triple-glazed windows can save you alot of money on energy bills in the long run. However, you will have to be willing to pay that extra bit of money upfront.
