Aluminium glazing, engineered for the way you live.
Every system is thermally broken, multi-point locked and powder-coated to last. Mix and match across your home — they'll all match perfectly.
Casement windows
The classic opener, reimagined in aluminium. Sightlines slim enough to carry far more glass than uPVC, in flush or stepped frames — single light or full multi-light runs.
Tilt & turn windows
Tilt inwards from the top for secure ventilation, or swing fully open to clean and for easy escape. A favourite for apartments, upper floors and contemporary builds.
Sliding & bay windows
Horizontal sliders and traditional bay or bow arrangements that fill a room with light. Aluminium's strength lets bays project further and sliders run larger and smoother.
Aluminium doors
Bi-fold, sliding, French and entrance doors to match your windows exactly — slim interlocks, big glazed panels and a flush threshold that opens the house to the garden.
RAL colours & finishes
Any shade in the RAL palette, different inside and out if you like, in matt, satin or textured powder-coat. Anthracite grey is our most-requested — we'll colour-match the rest.
A-rated thermal performance
Polyamide thermal breaks with warm-edge, argon-filled double or triple glazing. Warmer rooms, lower bills and no cold-bridging through the frame.
Stronger than uPVC. Slimmer by design.
Aluminium is the frame material architects specify when they want maximum light and minimum bulk. Here's what that means for your home.
-
Slim frames, more glass
Because aluminium is so strong, the frame can be thinner while carrying bigger panes — up to 30% more glass in the same opening than chunky uPVC.
-
Built to last decades
It won't warp, rot, swell or discolour. A quality powder-coated finish holds its colour for 25+ years with little more than the occasional wipe.
-
Warm and efficient
Thermally broken profiles and high-performance glazing close the old "aluminium is cold" gap completely — today's systems are A-rated.
-
Secure as standard
Multi-point locking, internal beading and the inherent rigidity of the frame make these windows genuinely tough to force.
-
Total design freedom
Any RAL colour, dual finishes inside and out, slim or flush sightlines — suiting everything from a Victorian terrace to a glass-wrapped extension.

The questions we're asked most.
How much do aluminium windows cost?
As a guide, supplied and fitted aluminium windows typically start around £650–£1,200 per window, depending on size, style, glazing and colour. The only way to know your exact figure is a free survey — we give a fixed, itemised price and there's no deposit to find out.
Are aluminium windows worth it compared to uPVC?
If you want slimmer frames, more glass, a far wider colour range and a longer lifespan, yes. Aluminium costs more upfront than uPVC but typically outlasts it and suits contemporary and premium renovations much better.
Are aluminium windows cold or prone to condensation?
Not modern ones. Every system we fit is "thermally broken" — an insulating barrier runs through the frame — and paired with warm-edge double or triple glazing. They're A-rated and condensation-resistant, a world away from the aluminium frames of decades ago.
How long do aluminium windows last?
A well-made, properly fitted aluminium window will comfortably last 30–45 years. The powder-coated finish is guaranteed for decades and the frame itself won't rot, warp or corrode.
Can you match a specific colour?
Yes. We powder-coat to any RAL colour, with different shades inside and out if you like. Anthracite grey (RAL 7016) is the most popular, but we'll match your render, brickwork or existing frames.
Do aluminium windows need planning permission?
Like-for-like replacements usually fall under permitted development, so no permission is needed. We'll flag anything worth checking if you're in a conservation area or a listed building.
How long does installation take?
Most homes are surveyed, manufactured and fitted within 6–10 weeks. A typical install of several windows takes one to three days on site, with minimal mess and full clean-up.
