Aluminium explained

Technical Guide to Aluminium Glazing

Why modern aluminium systems are widely used for windows, doors and glazed structures — and what matters when choosing a specification.

Modern aluminium windows and doors

Strong profiles and slim sightlines

Aluminium's strength allows window and door systems to use relatively slim frame sections while supporting substantial glazed areas. This makes it particularly useful for contemporary architecture, extensions and projects designed around natural light.

Low-maintenance powder-coated finish

Powder-coated aluminium requires straightforward routine cleaning rather than regular painting. Correct drainage, installation and maintenance remain important for long-term performance.

Modern thermal-break design

Current aluminium systems use engineered thermal breaks to reduce heat transfer through the frame. The final whole-window or whole-door U-value depends on the system, dimensions, glazing and configuration.

Security as a complete system

Security performance depends on the complete tested product specification, including frame, glazing, hardware and installation. Where a particular standard is required, it should be established before the product is specified.

Made-to-measure project flexibility

Aluminium is particularly useful where custom sizes, large glazed areas, wide openings or coordinated window-and-door packages are required. The right system depends on what the opening needs to do rather than aluminium being one single specification.

Windows, doors and roofs from Bristol

Ali-Co provides aluminium products for Bristol and surrounding areas, with supply-only and installation options depending on the project. We can help bring windows, doors and glazed roof products together as a coordinated specification.
