Black metal internal doors, often called Crittall style after the original steel window maker, have become one of the most wanted looks in home design. The slim black frames and gridded glass panels bring an industrial, architectural feel that suits both period homes and modern extensions. This guide covers where the look works, the choices you have and what it costs, so you can decide if it is right for your home.
What "Crittall style" actually means
The original Crittall doors and windows were made from thin steel sections, which allowed narrow frames and large panes of glass. The modern "Crittall style" look borrows that language: black frames, slim sightlines and a grid of glazing bars dividing the glass into rectangles. Most versions today are made from aluminium or steel-look profiles rather than heavy raw steel, which keeps them lighter, better insulated and easier to live with while keeping the same striking appearance.
Where the look works best
Black glazed internal doors earn their keep where they can divide space without blocking light.
- Between a kitchen and a dining or garden room: you separate the cooking smells and noise while keeping the whole space feeling open.
- Hallway to living room: a glazed screen and door let light travel through the house.
- Home office or snug: a glass partition gives you a quiet room that still feels connected.
- Broken-plan living: rather than one vast open space, black framed doors let you zone areas that can be opened up or closed off.
The look is strongest where there is light to borrow, so think about which rooms feel dark and could share light with a brighter neighbour.
Design choices to consider
A few decisions shape how the doors look and work.
- Single, double or a screen: a pair of doors or a fixed glazed screen with a door makes a real feature; a single door is a subtler touch.
- Glazing pattern: the number and spacing of glazing bars changes the feel, from a fine delicate grid to a bolder, simpler layout.
- Clear or textured glass: clear glass maximises light and openness; reeded or frosted glass gives privacy where you need it, handy for a study or a downstairs cloakroom.
- Finish: matte black is the classic, though the same style comes in other dark tones.
Getting the wider look right
Crittall style doors sit best when the surrounding scheme supports them. They pair naturally with the industrial-meets-warm mix that has stayed popular: exposed brick or concrete tones, warm timber, and touches of brass or aged metal to stop the black feeling cold. If you like the black framed glazing look elsewhere in the home, it carries through beautifully to external glazing too, and our aluminium sliding and bi-fold doors and heritage aluminium range share that same slim black profile, which helps a scheme feel joined up inside and out.
What black metal internal doors cost
Prices vary a lot with the material, size and whether you want a single door or a full glazed screen. As a rough 2026 guide, a Crittall style internal door often falls somewhere between about £400 and £1,200 supplied, with larger double doors and glazed screens rising well beyond that once you add fitting. Steel costs more than aluminium-look alternatives. These are ballpark figures rather than fixed prices, so ask for a quote once you know the opening and style you want.
FAQs
Are Crittall style doors made of real steel?
Some are, but many modern versions use aluminium or steel-look profiles instead. These give the same slim black framed appearance while being lighter, better insulated and easier to fit and maintain than heavy raw steel.
Do black framed glass doors make a room darker?
Usually the opposite. Because so much of the door is glass, they let light pass between rooms, which often makes a space feel brighter and more open than a solid door would. Clear glass maximises this; choose textured glass only where you need privacy.
Where should I use Crittall style internal doors?
They work best where you want to divide a space without losing light, such as between a kitchen and dining area, a hallway and living room, or to create a home office. They suit broken-plan living where rooms can be opened up or closed off.
Are black metal internal doors still on trend for 2026?
Yes. The Crittall inspired look has moved from a short-lived trend to a settled favourite, valued for the way it adds character and shares light. Pairing it with warm timber and brass keeps it feeling current rather than clinical.
