Want the contemporary-yet-timeless look of an aluminium window, but the efficiency of PVC frames? Thermal break aluminium windows are the solution to your dilemma.
Pioneered by the British firm Senior Architectural Systems, this ingenious feature really does give you the best of both worlds. In thermal break windows, polyamide material is sandwiched between the inside and outside of the aluminium frame, creating an insulating ‘barrier’ between both panels. The result? Temperature conductivity is slashed, allowing the window to much more effectively keep heat in and cold out – perfect for keeping energy bills in check.
As an added bonus, your home will be cooler in the summer. Noise from the outdoors will find it harder to make its way inside too, giving you a more peaceful home than ever before. Aluminium thermal break windows are simply the best of the best.
We offer a 10 year guarantee on all aluminium profiles and 25 years for the powder coating element

Located in the Yorkshire city of Doncaster, Senior Architectural Systems is one of the world’s leading manufacturers of aluminium windows.

No, not every manufacturer offers this technology. All of the windows we supply come with it installed, however. We highly recommend choosing thermal break windows for the efficiency benefits they provide.
Yes, significantly so. Aluminium won’t rust, corrode, crack or rot, making it the perfect material for this application.
