Whether it’s the climate emergency or the rising cost of energy bills, we’re all looking at ways to make our homes more energy efficient. If you’re looking at replacing your windows, you may be wondering whether it’s worth paying extra for triple glazing over double glazing.

Here are a few things to consider.

The energy efficiency benefits of triple glazing

Heat gain and heat loss through windows are responsible for 25%–30% of a typical home’s heating and cooling needs. It means having thermally efficient windows makes very good sense.

Triple glazing is more thermally efficient than double glazing, so you might think it’s worth paying extra for triple glazing over double glazing.

Not necessarily.

If you are replacing ageing single or double-glazed aluminium windows with modern triple-glazed aluminium windows, you will notice a huge difference in the comfort levels of your home.

However, you will also notice a huge difference if you replace your windows with the most thermally efficient aluminium double-glazed windows. Evoke, our aluminium window and door system, for example, offers exceptional thermal efficiency in both double and triple-glazed versions.

The increased thermal efficiency of triple glazing doesn’t necessarily translate to a big difference in energy costs. When you compare the best modern aluminium double glazing with the best modern aluminium triple glazing, the energy savings may not be as significant as you think.

On the other hand, if your main concern is a reduction in energy use for environmental reasons, triple glazing obviously has its advantages.

The additional benefits of triple glazing

Of course, it isn’t just energy efficiency where it might be worth paying extra for triple glazing over double glazing.

Triple-glazed windows can be better at reducing noise levels than double-glazed windows. This can be a huge advantage for homes in the South East, especially if you’re on a flight path or near a busy road.

Other things to consider when looking at triple glazing

There are a few more options to consider when you’re wondering if it’s worth paying extra for triple glazing over double glazing.

Triple-glazed windows are heavier than double-glazed windows. This means they may not be suitable for all homes or that additional structural reinforcements will be needed.

It’s also important to know that triple-glazed windows may not let as much light in as double-glazed windows. This makes your choice of window frame all-important. Aluminium windows have slimmer frames than PVC-U windows. Our Evoke aluminium windows have the slimmest frames on the market. In fact, they’re up to 30% slimmer than comparable aluminium windows, which equates to a glass area that’s 12% larger. This could help to compensate for the loss of light as a result of triple-glazed windows.
