If you want ultra-modern, flush-fit windows but don’t want to compromise on thermal and sound insulation, there’s no better option on the market than triple-glazed aluminium windows.

Whether you’re hoping to modernise an ageing home or you’re building a new property, you won’t have to settle for anything less than the best with Klosen: all of our aluminium window and door installations are guaranteed for a decade.

Are Triple-Glazed Windows Worth Choosing?

Although double-glazed windows have now become the industry standard, many homeowners are now turning to triple-glazed windows instead. Why? Here are a few key attributes that make them worth the extra cost:

Energy bills are higher than ever. Triple glazing is much more efficient than double glazing, allowing it to keep more heat in and, in turn, saving you money on your heating bill. The transformation will be particularly noticeable if you’re replacing old double glazed windows.

As well as boasting improved thermal insulation, triple glazing is better at insulating sound too. Whether you’ve got roadworks going on outside or are unlucky enough to have a noisy neighbour, the sound will be less intrusive with triple glazing installed.

Triple glazing is tougher. If you’re concerned about home security, triple glazing is well worth considering as it’s significantly harder to break.

The improved thermal efficiency of triple glazing means you’re less likely to experience condensation during the cooler months.

Why Choose Aluminium?

Aluminium-framed windows are an exciting, ultra-modern alternative to more traditional wood or PVC options. Because of aluminium’s inherent strength, window frames constructed from it can be slimmer than any wood or PVC frame without compromising on security, allowing for the fitment of larger panes of glass to let more natural light into your home.

Besides their stunning looks, aluminium windows are immensely durable – much more so than PVC or wood equivalents. They won’t rust, rot or crack over time, so when you choose aluminium, you really are making a long-term investment in your property.

They’re also no more challenging to install than conventional windows. Here are just a few of the installations we’ve recently completed:

FAQs

Are there any other advantages to choosing aluminium?

Yes – it’s the most sustainable window frame material out there. It’s very easy to recycle, making it ideal for businesses or homeowners who want to prioritise sustainability.

Are triple-glazed aluminium windows as efficient as PVC or wood items?

Traditionally, aluminium is less efficient as the material conducts temperature more than wood or PVC. However, thanks to the technology packed into our windows – like a polyamide thermal break – they’re now extremely efficient.

How much do your windows cost?
