Triple-glazed windows and doors

Triple glazing is a relatively new innovation in sustainable window technology. It's a big step up from double glazing in terms of thermal efficiency, soundproofing and condensation reduction.

How does it work? The clue's in the name. Like double glazing, triple glazing incorporates several layers of glass to help trap heat indoors. While double glazing has two panes, triple glazing uses three.

In modern windows, the gaps between the panes are filled with an inert gas. Because these gases are excellent insulators, they help to keep your home extra cosy.

Yes – if you choose Calder. Our triple-glazed doors and windows are specially designed with extra-thick (40-millimetre) units, which improves energy efficiency by up to 40%.

This is especially beneficial in our current climate. At a time when environmental concerns and energy bills are increasing, it makes sense to choose an option that helps address both.

Triple-glazed windows are considered eco-friendly because they're effective heat insulators. They help to reduce heat loss in our homes, which makes our central heating systems more efficient. This, in turn, means less energy usage and a small step towards a brighter future for Planet Earth.

Most of our triple-glazed windows are rated A++ on the BFRC's energy performance scale. This is the highest possible rating.

Yes. Triple-glazed doors and windows are great insulators – and this superpower works both ways. As well as trapping heat inside your home, they help to keep heat out.

In the UK, this is usually a good thing. In winter, triple glazing makes central heating more efficient by reducing heat loss. In summer, it keeps our homes nice and cool without the need for expensive air conditioning.

Usually, yes. Triple glazing adds an extra glass barrier between your home and the outside world, which can help to deaden traffic noise and other nuisance sounds.

You can improve its sound insulation properties even more by applying a simple plastic window covering.

We can't promise it will stop condensation completely. However, it will almost certainly reduce it.

Condensation forms when moist, warm air touches a cooler surface. With triple glazing, the gaps between the panes of glass help to trap warm air. This means the window itself stays warmer and is less likely to attract drips.

This has a bonus benefit: it helps your windows last longer.

Since our products are tailor-made for every customer, it's impossible to provide cut-and-dry costs without knowing exactly what you're looking for.

Generally speaking, however, triple-glazed windows cost a little more than their double-glazed counterparts. This is because of the extra materials they use, as well as the complexities of their manufacturing process.

Is triple glazing worth the extra cost? If you buy through Calder, yes. Our triple-glazed doors and windows are among the most energy-efficient models available in the UK. This means you could save a packet on your energy bills, even if you're upgrading from modern double glazing.

They unlock a host of other benefits too, such as reducing condensation and traffic noise.
