Aluminium doors — supply only, delivered in about a week
Aluminium single and Crittall-style doors, supplied only.

The Crittall-style options are the ones with the fine internal glazing bars that read as period steel windows. They are the profile conservation officers tend to accept where a chunky uPVC door would be refused, and they have become the default in extensions and garden rooms because the sightlines are so much finer.

Aluminium doors — questions we get asked
Are aluminium doors cold?
Not modern ones. A polyamide thermal break splits the inner and outer halves of the frame so heat cannot conduct straight through. Pre-1990s aluminium had no break at all, which is why those old frames streamed with condensation and gave aluminium its reputation.
What is Crittall style?
Fine internal glazing bars in a slim dark frame, imitating the steel windows of the 1920s and 30s. It is a look, not a material — these are aluminium, not steel, so they do not rust and they meet current thermal standards.
Can I have a different colour inside and out?
Yes — dual colour is standard on aluminium. Anthracite outside and white or a warm grey inside is the common request. It adds a little to the lead time because the frame is coated twice.
Is aluminium worth the extra over uPVC?
For a door you look at every day, on a house you are keeping, usually yes — slimmer frame, longer life, any colour. For a utility door out of sight, it is hard to justify.
What does the powder coat guarantee cover?
Typically 25 years against the finish cracking, peeling or chalking. Coastal locations need a marine-grade specification — standard powder coat fails within about a mile of salt water.
