Why Choose Aluminium Windows for London Properties?

London’s climate, architecture, and planning constraints demand windows that perform. Aluminium is a superb choice because:

Slim sightlines, maximum glass area

— less frame, more view

Excellent durability

— no warping, rotting or corrosion

Strong structural performance

— supports large panes, tall designs

Thermal efficiency

— modern thermal break technology enables low U-values

Low maintenance

— minimal upkeep compared to timber or older frames

Design flexibility

— wide selection of finishes, RAL colours, heritage or modern styles

Security & compliance

— compatible with PAS 24 / Secured by Design specifications

These advantages make aluminium windows highly popular with developers, architects, homeowners, and in heritage or conservation areas.
