Alu-clad windows

Why choose alu-clad windows?

When it comes to installing new windows, many homeowners are opting for aluminium-clad designs, and it’s easy to see why. In an alu-clad window, an all-timber frame is covered with an external aluminium skin, skilfully designed to blend in perfectly with the frame shape and design.

Get the best of both worlds

Alu-clad windows from Rationel combine the best features of timber and aluminium into a second to none, premium system:

Warm and natural wood-finished beauty on the inside.
We use high quality softwood sourced from sustainable northern European forests, which means that 99.7% of the wood we use is FSC® certified.
External weather shield made of aluminium.
The aluminium profiles protect the timber and extend the lifetime of the windows while minimising the need for maintenance.

The result?

Every room in your home features beautiful, natural wooden windows while the external frame is virtually maintenance free, and longer-lasting, thanks to the durable aluminium cladding.

It’s not surprising that aluminium/wood windows are so popular in Ireland, given the benefits they deliver:

Great weather (and burglar) protection

Alu-clad windows can easily withstand the challenging Irish weather thanks to the hardwearing aluminium skin over the timber frame. This aluminium layer also makes the whole window more robust and therefore even more burglar-proof.

How we test for wind and water

Low maintenance windows

Timber window frames look great but only if they are regularly maintained. In a country such as Ireland, with a wet and windy climate, a wooden window frame may need a fresh coat of paint every year. Studies commissioned by Rationel show that the lifetime of an all-timber window can be extended by over 20 years when the external frame is protected by aluminium.

With wood-alu, no repainting needed, just regular cleaning with soapy water keeps alu-clad frames looking good as new, plus annual oiling of hinges, handles and other moving parts.

Customised window design

Have the freedom to choose your favorite window style and features. Alu-clad windows are available in multiple colours, shapes, finishes and glass options to suit any property, new or old.

Any disadvantages of alu-clad windows?

Not really. Alu-clad windows suit any type of project, and even though they may be initially more expensive than all-timber frames, so called ‘lifetime costs’ are much lower as you won’t need to repair or repaint the external frame, and the windows will have a much longer lifetime, even in the most demanding locations.
