Slimline aluminium casement windows will modernise any home

Aluminium casement windows boast a distinctive thin frame design for a sleek look which will seriously enhance the aesthetic appeal of any home. With over 150+ RAL colours and a number of wood effects to choose between, we can ensure the perfect design to complement your home. With a range of both traditional and contemporary window furniture pieces, you’ll be able to add the finishing touches to suit your individual tastes.

Our modern aluminium casement windows are highly energy efficient, thanks to high-quality double or triple glazing and a unique polyamide thermal break. With A+ energy ratings attainable, you’ll be able to save money on your heating bills and external noise making its way into your home will be minimised too. The slender framing will ensure that plenty of light makes its way inside, and thanks to the latest security innovations and features, your home will be protected from potential intruders. We finish the frames in a protective coating, which eliminates them from fading, rotting or corroding. Another benefit is that aluminium is maintenance-free, so they’ll continue to look like new for years to come.
