Aluminium windows for modern London homes

Aluminium windows are ideal for contemporary London homes, extensions and refurbishments where you want slim frames, large glass areas and a clean, modern look. They sit comfortably within wider glazing schemes across the property.

Why choose aluminium windows?

  • Aluminium windows offer slim sightlines, strong frames and stable performance, which works well for modern house window replacement projects. They suit large openings, shaped windows, fixed light windows and aluminium bay windows where generous glass and light are a priority.

  • Maintenance is straightforward: aluminium frames are factory finished, so in most homes they need just periodic cleaning. With modern thermal breaks and high‑performance glazing, aluminium windows double glazed or triple glazed can support energy efficiency and help manage double glazing window costs over the life of the property.

  • Aluminium also works well alongside other window materials in the same home. Homeowners often combine aluminium windows with timber sash windows, timber casement windows or bespoke timber windows on key elevations and use more contemporary styles on garden‑facing sides.

Aluminium windows to suit your project

Aluminium is well suited to projects where the design calls for a modern feel and strong visual links between inside and outside. Typical uses include:

  • Extensions and open‑plan spaces

    Large panes, slim frames and carefully placed fixed light windows can create wide views and bright interiors, often with roof lanterns above.

  • Contemporary new builds

    Bespoke aluminium windows, shaped windows and roof lanterns can be combined to create consistent modern lines across all elevations.

  • Urban homes and flats

    Slim aluminium casement windows, tilt and turn windows and top hung window layouts provide good ventilation, easy cleaning and a neat appearance in tighter spaces.

  • Mixed‑material projects

    Timber sash windows or timber bay windows at the front can sit alongside aluminium windows sliding or aluminium tilt and turn windows at the rear, where larger glazed areas and different proportions are possible.

  • Mixed‑material projects

    Timber sash windows or timber bay windows at the front can sit alongside aluminium windows sliding or aluminium tilt and turn windows at the rear, where larger glazed areas and different proportions are possible.

Many projects involve working with architects and glazing designers who specify systems such as Origin windows, Schüco windows, Reynaers windows, Rationel windows, and Velfac windows, so aluminium windows become part of a coordinated package.

Aluminium window styles

Aluminium can be fabricated into a wide range of window styles, from simple opening units to more complex shapes and arrangements. The aim is to match how each room is used and how each elevation looks from outside.

Common aluminium window styles include:

Aluminium casement windows

A practical choice for many rooms, with flexible opening sizes and directions.

Aluminium tilt and turn windows

Often used on upper floors and in flats, giving inward opening for cleaning and secure tilt positions for ventilation.

Fixed and picture windows

Large non‑opening panes used to frame views or bring in maximum light, sometimes combined with a sliding system or roof lanterns in the same space.

Aluminium sash windows

Designs that echo the proportions of sash windows or timber sash windows while using slim aluminium profiles.

Shaped windows and bay windows

Bespoke aluminium windows made as bays, angled corners, or shaped windows to follow rooflines and architectural details.

The brands we work with

Colours, finishes and details

Aluminium windows are powder‑coated in a wide range of RAL colours. Many homeowners choose classic whites and greys; others prefer deeper tones that work well with London brickwork or cladding.

Dual‑colour options allow one shade on the outside and another on the inside, so interior schemes with bespoke wooden windows, bespoke timber windows, or other finishes can be matched more closely. Handles and hardware come in various finishes, and careful attention to seals and sightlines helps aluminium windows sit neatly beside other bespoke windows on the same elevation.

Energy efficiency and glazing options

Current aluminium window systems use thermal breaks and modern glazing to support comfortable indoor temperatures and good acoustic performance. There is scope to choose glazing according to how each elevation is exposed to weather and noise.

Aluminium windows options
Triple glazing window
Double glazing window
  • Double glazing

    The most common choice for London homes and a practical balance between comfort, energy efficiency and cost. It suits most typical openings, from casement windows to bay and sash styles, and meets current building regulations for new and replacement windows.

  • Triple glazing

    Recommended where extra insulation or noise reduction is important, such as near busy roads, rail lines or flight paths. Triple glazed units improve thermal performance, reduce outside noise and work well in larger bespoke windows, aluminium bay windows and rooms with significant glass areas.

  • Acoustic glazing

    Designed to reduce outside noise in homes located near busy roads, rail lines, flight paths or lively urban streets. Acoustic units use laminated glass and specially tuned interlayers to dampen sound, which helps rooms feel calmer and more comfortable without changing the look of the window. It can be specified in most aluminium window styles, including casement, tilt and turn, fixed light and bay windows.

Aluminium, timber and composite windows

Many projects use more than one window material. Aluminium suits large openings, modern elevations and spaces where slim frames and strong lines are important. Timber windows, bespoke timber windows and timber sash windows are often preferred for period façades and traditional street‑facing elevations. Composite systems offer a timber look internally with a different outer surface.

On some homes, aluminium is the main material on garden‑facing sides with bespoke aluminium windows and roof lanterns, while the street elevation keeps timber sash windows or timber bay windows to stay in keeping with neighbouring properties. Other projects choose a full package that mixes aluminium, timber windows and composite systems according to how each façade is used and viewed.

FAQ

Well‑specified aluminium windows with quality powder‑coated finishes are designed for long service lives. In practice they are often chosen for projects where stability, low maintenance and long‑term appearance matter. All our aluminium windows also come with a manufacturer's warranty, giving you added peace of mind on both the frames and the finish.

In many London areas, aluminium windows are used at the rear or on extensions, while the front keeps timber sash windows, sash box window designs or bespoke timber windows. Aluminium windows sash‑style can follow similar proportions, which helps the new work sit comfortably alongside existing architecture.

Most systems accept both aluminium windows double glazed and triple glazed window units. The choice depends on priorities such as warmth, noise reduction and budget. During the survey and design stage we discuss which specification suits each elevation.

Yes. Mixed schemes are common: for example aluminium casement windows on the rear elevation, timber bay windows at the front, and fixed light windows on side walls. Projects sometimes also include Velfac doors, Rationel door products or similar systems, and aluminium windows can be chosen to work well alongside these.

Costs vary with size, style, glazing, brand and any bespoke features. Large bespoke aluminium windows, aluminium bay window designs and complex shapes usually sit at a higher level than basic double glazing windows. After a survey we provide a clear breakdown of windows installation price for the proposed specification.

Yes. Many projects involve bespoke windows packages that bring together aluminium windows, timber windows, timber sash windows, shaped windows and roof lanterns. The aim is to make sure proportions, sightlines and glazing choices feel consistent across the whole home.
