Extensive Colour Range

Aluminium goes through a powder coating process which means you can select any RAL colour, offering virtually unlimited colour possibilities.

Standard architectural colours including Anthracite Grey, Black and White, to suit most commercial and residential projects.

Bespoke RAL colours match corporate branding, complement surrounding buildings, or achieve specific architectural visions with an uplifted cost.

Dual colours provide different internal and external appearances – common in commercial developments where external aesthetics must match building design whilst internal frames coordinate with interior décor.

Why Specify Aluminium Windows?

Aluminium’s inherent strength allows for much slimmer frames than UPVC, maximising glass area for better views and more natural light. This makes aluminium the material of choice for architecturally significant projects, large commercial glazing, commercial aluminium windows, and heritage steel window replacements.

Slim Sight Lines Maximise Light

Aluminium frames can be 40-50% slimmer than equivalent UPVC profiles whilst maintaining structural integrity. This translates to significantly more glass area, which can transform basement conversions requiring maximum light, commercial offices prioritising natural daylight, apartments with limited window openings, and contemporary architecture where minimal frames are integral to design.

The difference is substantial: a 2m x 2m window in aluminium provides approximately 15-20% more glass area than UPVC, flooding interiors with noticeably more natural light.

Superior Strength for Large Openings

Aluminium’s strength-to-weight ratio is exceptional. This allows for larger window sizes and configurations that would be impossible with UPVC, including floor-to-ceiling glazing in commercial developments, wide-span windows in modern residences, curtain walling systems, and structural glazing applications where frames must support significant glass weight.

For architects and developers pushing design boundaries, aluminium enables glazing solutions that other materials cannot achieve.

Exceptional Longevity

Aluminium doesn’t corrode, rust, warp, or rot. Powder-coated finishes are extraordinarily durable, maintaining appearance for 40+ years with minimal maintenance. For prestige developments, commercial buildings with long-term value considerations, or coastal locations where weather exposure is extreme, aluminium’s proven longevity justifies initial cost premiums.

Buildings fitted with quality aluminium windows in the 1970s and 1980s often still have original frames in excellent condition – a testament to the material’s durability.

Thermally Efficient When Specified Correctly

Modern aluminium windows incorporate thermal breaks: insulating barriers within the frame that prevent heat transfer. Quality aluminium achieves excellent energy efficiency, comparable to UPVC when specified with appropriate glazing.

This makes aluminium suitable for new builds requiring building regulations compliance, refurbishments improving thermal performance, and commercial buildings where operational costs matter.

Heritage Steel Window Replacement

Aluminium perfectly replicates heritage Crittall windows and steel-framed glazing common in 1920s-1950s buildings. Slim profiles match original steel aesthetics whilst incorporating modern thermal performance and eliminating the maintenance and corrosion issues that plague steel windows.

For industrial conversions, Art Deco buildings, schools, hospitals, and commercial premises originally fitted with steel windows, aluminium provides authentic appearance with contemporary performance and longevity. This also makes aluminium particularly popular for architectural aluminium windows where heritage styling must be combined with modern performance standards.

Commercial Aluminium Windows

Commercial aluminium windows are widely specified for offices, schools, healthcare facilities, retail developments, industrial units and public buildings. Their strength, durability and slim sightlines make them ideal for projects where appearance, longevity and performance are equally important.

Available in a wide range of configurations and finishes, aluminium commercial windows can be manufactured to suit both contemporary and traditional building designs whilst meeting demanding performance requirements.

When to Specify Aluminium Over UPVC

Aluminium costs more than UPVC. This investment is justified when:

  • Slim aesthetics are architecturally important – Modern developments, prestige projects, design-led residential
  • Large window sizes exceed UPVC capabilities – Floor-to-ceiling glazing, wide spans, structural glazing
  • Heritage steel replacement is required – Industrial conversions, 1920s-1950s buildings, Crittall replacements
  • Longevity justifies the premium – Prestige commercial developments, long-term investment properties
  • Coastal or exposed locations – Aluminium’s corrosion resistance suits harsh environments

For standard residential developments, social housing, or projects where budget constraints apply, UPVC typically delivers better value. Aluminium excels where its specific advantages justify cost premiums.
