Aluminium windows in London, less frame, more sky.

Aluminium's strength-to-weight ratio is what buys the look: where a uPVC frame needs 70mm of plastic and steel, a slimline aluminium window carries the same pane on roughly 40mm of visible frame, and steel-look ranges go slimmer still. That means larger uninterrupted panes, more daylight into narrow London plots, and elevations that read as glass rather than frame.

It's the right material wherever the opening is the architecture: rear extensions, gable glazing, corner windows and floor-to-ceiling screens. For standard openings on a budget, our uPVC windows remain the sharper buy. We make both, so we'll tell you straight.

Every profile we install is thermally broken: a polyamide barrier separates the outer and inner aluminium so the frame doesn't conduct the cold indoors. With a 28mm argon-filled double-glazed unit you get around 1.4 W/m²K; triple glazing takes that to roughly 1.0 W/m²K, with condensation-free frames and Building Regulations comfortably met.

Finish is polyester powder coat, oven-cured for a hard, UV-stable skin that never needs painting, in any RAL colour (matt, satin, gloss or textured), with dual-colour available so the outside can match the render and the inside the joinery.

Aluminium bifold doors are the London extension's default for a reason: 2 to 7 leaves running on stainless rollers, spanning up to about 6.5 metres, folding flat to one or both sides. Specify a traffic door in odd-leaf sets and you keep an everyday door without folding the whole run. Low-threshold options run flush with the floor inside and out.

Configuration is written as leaves-left / leaves-right / traffic door. We'll sketch the options at survey:

Where a bifold gives you the full opening, a slider gives you the biggest fixed glass: two or three panes, each up to around 2.5m wide, with interlocks as slim as 25-35mm on premium systems. Nothing stacks into the room, nothing interrupts the garden view in winter, and the action stays fingertip-light even on 250kg panels. The honest trade-off: you can only ever open half to two-thirds of the aperture. We fit both, and will tell you which suits the room rather than the brochure.

Aluminium entrance doors bring the same discipline to the front of the house: rigid slab construction that never warps or swells, flush modern panels or heritage styles, powder-coated to any RAL, with multi-point locking and PAS 24 security options as standard. Oversized pivot doors and glazed side screens turn a hallway into an arrival. Every set is made to your opening, not trimmed from stock, by our own factory.

The same fabrication line produces commercial-grade aluminium: shopfront screens, ground-floor treatments, communal entrance doors with access control prep, and curtain-wall sections for offices and schools. If your project is a business premises, start at our commercial glazing London service: same team, with the specification written for footfall, security shutters and signage zones rather than living rooms.
