Double Glazing VS Triple Glazing – Which is best and why?

 

A few months ago, we shared an article on the problems with single glazing. While the benefits of replacing your single-glazed doors and windows with new, double-glazed ones are quite evident, there are still some more options to consider. For example, you might be wondering whether it would be an even better investment to upgrade to triple glazing instead.

The difference between double and triple glazing is in the number of glass panes enclosed within a sealed frame, with a space between them – also known as insulated glazing.

But what are the benefits of each option? And overall, which one is the best choice for you and your home?

Keep reading to find out.

 

Triple Glazing

As you would expect, due to its advanced manufacturing technique and the additional glass, triple glazing is a more expensive option.  There are, however, some great benefits to it that must be taken into consideration when deciding to upgrade your doors.

The most obvious reason for choosing triple glazing is the advanced thermal efficiency, which helps save on heating bills. However, the truth is that, while energy savings from switching from single to double glazing are considerable, when it comes to the switch from double to triple glazing, they account for only 5% improvement in the overall energy performance of a house. Such an improvement is of greater significance in very cold climates or depending on the size of your property.

Triple glazing also offers great sound insulation. If your house is situated on a busy main road with heavy traffic, then it might be worth investing in triple-glazed doors and windows, as they could achieve a noise reduction of up to 2 decibels compared to double glazing. On the other hand, if you do not live in an extremely noisy environment, then double glazing is just as efficient at reducing disturbance from any unwanted noise.

 

Double Glazing

Double-glazed doors and windows tend to be less expensive and they are the most popular choice due to their great overall performance.

While triple glazing might be superior in terms of thermal efficiency, the extra glass pane also means that less heat from the sun will be able to make its way into your home. On the contrary, double glazing is able to harness more solar energy, which is quite beneficial on sunny days.

Another advantage of double glazing is that it is lighter and, thus, it puts less strain on the frames and hinges of opening sashes. This is not something that you will be able to appreciate right away but, in the long run, it could potentially make a huge difference for your home.

Lastly, it is worth mentioning that triple glazing sealed units tend to break down more often than double glazed sealed units and, once out of guarantee, they cost more to replace.
