Choose the quality and performance

What makes our aluminium windows so great?

Made in Britain, our aluminium windows feature standard & multi-chambered EnergyPlus profiles from a market-leading supplier - Liniar. Making sure that your home is the most efficient it can possibly be, unnecessary conductive steel reinforcements are removed, and multi-chambered profile technology is utilised to keep the interior comfortable & warm. This ensures best double glazing Window Energy Ratings (WER) and U-values, as low as 1.0 W/m²K.

Our stunning range of aluminium windows from market leading supplier - Smart Architectural Aluminium, are highly energy efficient, thanks to their cutting-edge polyamide thermal break technology. In this instance, the term ‘thermally broken’ actually has a positive meaning, basically referring to the way that the window has been constructed; providing a high level of insulation. Our aluminium windows can achieve Window Energy Rating B and U-values of up to 1.4 W/m²K.

All our aluminium windows offer a high level of security and utilise the most secure double glazing, locking mechanisms and hardware around.
