Aluminium · within the M25
Crittall-style doors and internal screens.
Steel-look framing in aluminium — for glazed partitions, garden doors and rooms divided without losing the light.
What they do
Divide a room without dividing the light
The look comes from the original steel windows of the 1920s and 30s — narrow black frames, glass split into a grid. We build it in aluminium, which gives the same slim, dark line without the weight of steel and without the rust. Most of the work we do in this style is internal: a kitchen separated from a dining room, a home office carved out of an open-plan floor, a hallway that keeps its light. It also works on a rear elevation, where the grid picks up the proportions of period glazing bars on the front of the house.
How ours are built
Slim sightlines
Aluminium holds the glass in a narrow section, which is what makes the grid read as a fine line rather than a heavy frame.
Internal or external
Internal screens don't need a thermal break. Anything facing outside is built on a thermally broken profile.
Grid set out to your room
The spacing of the bars is drawn to suit the opening rather than dropped in as a standard pattern — corner posts, door leaves and fixed panels are set out together.
Matt black, or any RAL
Matt black is the usual choice for this look, but the frames are powder-coated and any RAL colour is available.
Common questions
Is this the same as Crittall?
No. Crittall is a trademark of a British manufacturer that makes steel windows. What we make is a crittall-style product in aluminium — the same slim, dark, gridded appearance, built in a different material. Aluminium is lighter, doesn't rust, and takes a powder-coated finish in any colour.
Can I use these inside without losing heat?
Internal screens sit between two heated rooms, so a thermal break isn't needed and the frames can be slimmer. If a screen faces outside — a garden door, or a partition against an unheated space — we build it on a thermally broken profile instead.
Can the grid match my existing windows?
Often, yes. If the front of the house has period glazing bars, we can set the grid out to pick up similar proportions so the two read as related rather than unconnected. We take the sizes at survey and draw the layout before anything is made.
