Aluminium doors
Aluminium is the material of choice for large, slim-framed doors. It is stronger than timber and stiffer than composite, which means it can carry larger panes of glass in narrower frames – more light, less frame. Modern thermally broken aluminium doors perform to a high energy efficiency standard and come in powder-coated finishes that hold their colour for decades without repainting.
Why aluminium?
Aluminium door construction
All aluminium doors we supply use thermally broken aluminium profiles. The frame is extruded aluminium divided into two chambers – inner and outer – separated by a polyamide insert. The polyamide has very low thermal conductivity, which physically prevents heat from passing through the frame.
Standard specification includes:
Multi-chambered thermally broken aluminium profiles.
Polyamide thermal break insert between the inner and outer frame sections.
Double or triple glazed sealed units with low-E coating and warm-edge spacers.
Multipoint locking with anti-snap, anti-drill, anti-pick cylinder.
Powder-coated finish in any RAL colour, anodised or woodgrain foil.
Stainless steel hardware and weather-sealed thresholds.
Aluminium door types
Aluminium door sets for front and rear access, available in flush panel, part-glazed and fully glazed configurations with slim sightlines and a clean appearance that suits both modern and period properties. All residential doors we install are thermally broken, PAS 24 certified, and Secured by Design accredited as standard.
Aluminium sliding doors track horizontally on a precision roller system, with one or more panels sliding behind fixed panels. They provide the largest uninterrupted glass area of any door type – ultra-slim systems achieve sightlines as narrow as 20mm. The right choice where maximum glass and unobstructed views are the priority.
Aluminium bifold doors fold and stack to one or both sides, opening the full width of the aperture between the house and garden. Suited to kitchen extensions and rear living spaces. Slim aluminium frames maximise the glass area. Available in two to seven leaves.
Two-leaf aluminium door sets opening outward from a central meeting point. Suited to smaller rear openings and as part of a larger glazed extension where bifold or sliding is not required. Available in standard and Crittall-style profiles.
Aluminium patio door sets with large glazed panels for rear garden access. The term is used for both sliding configurations and outward-opening French door sets. Suited to openings where a clean, low-profile threshold and maximum light are the priority.
Aluminium doors with steel-look slim black profiles, replicating the aesthetic of original Crittall steel windows. Aluminium Crittall-style doors offer the same heritage aesthetic at a lower cost and weight than original steel, with better thermal performance.
Aluminium pivot doors rotate on a floor-to-ceiling pivot mechanism rather than conventional side hinges. Available as a statement front door with panel sizes up to 2,000 × 4,000mm in a single leaf. Concealed hinges support doors up to 500kg. U-values from 0.65–0.72 W/m²K. PAS 24 certified and Secured by Design accredited. The right choice for modern new builds, architect-designed properties, and high-end residential entrance upgrades.
Purpose-built aluminium security doors with enhanced resistance to forced entry. Certified to PAS 24:2022, Secured by Design, and, at the highest specification, STS202 burglar resistance rating. Available with multipoint heavy-duty locking, reinforced frames, anti-crowbar rebates, and smart locking options including fingerprint scanners. Suited to residential properties requiring above-standard security, commercial premises, and communal entrance doors.

Specification
Thermal performance
All aluminium doors we supply are thermally broken as standard – polyamide inserts between the inner and outer frame sections prevent heat transfer and eliminate condensation on the frame. U-values are measured for the complete door set (frame and glass combined), not the glass unit alone.
Security certification
All aluminium doors we install carry PAS 24:2022 certification as standard. Secured by Design (the official UK police accreditation scheme) is available across our residential ranges. Properties on Secured by Design developments suffer up to 75% less burglary than non-accredited equivalents.
Standard security specification:
PAS 24:2022 certified door set.
Multipoint locking – minimum three locking points.
Anti-snap, anti-drill, anti-pick cylinder.
Toughened or laminated safety glazing throughout.
Secured by Design accreditation is available on all residential ranges.
Colour and finish
Aluminium doors are available in three main finish types:
Powder coat – the most common finish. RAL colour applied electrostatically and baked on. Durable, UV-stable, available in any RAL colour, including dual-colour (different inside and out). Gloss, satin, and matte options available.
Anodised – an electrochemical process that hardens the surface of the aluminium itself rather than applying a coating. Available in silver, champagne, bronze, and dark bronze. Highly scratch-resistant. The traditional choice for slim-profile commercial and high-end residential systems.
Woodgrain foil – a vinyl foil laminated over the powder-coated frame, replicating the appearance of timber grain. Popular where the appearance of a timber door is required with the performance of aluminium.
FAQ
Modern thermally broken aluminium doors are highly energy efficient. The polyamide thermal break physically prevents heat transfer through the frame. When combined with a double or triple glazed sealed unit, a good aluminium door set achieves U-values comparable to high-performance composite doors.
No. Aluminium does not rust. It forms a natural oxide layer that prevents further corrosion. Powder-coated and anodised finishes provide additional surface protection.
A quality thermally broken aluminium door has a typical service life of 40–50 years with no maintenance beyond cleaning. The powder-coated finish does not require repainting.
All doors we install are PAS 24:2022 certified with multipoint locking and anti-snap cylinders. Secured by Design accreditation is standard across our residential ranges. Security door specifications are available for higher-risk applications.
A wide range of RAL and heritage colours in gloss, matt and woodgrain-effect finishes. Most manufacturers offer dual-colour - different inside and out. Anthracite grey, black, chartwell green and French grey are currently the most popular choices in London.
Yes. Crittall-style aluminium doors are frequently used in conservation areas and listed buildings as a like-for-like replacement for original steel Crittall windows and doors. We advise on what is achievable within planning and listed building consent requirements for each project.
Single-door installations (front door, back door, French door) typically take one day. Bifold and sliding door systems typically take one to two days depending on opening size and structural work required.
