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.
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.
Black glazed internal doors earn their keep where they can divide space without blocking light.
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.
A few decisions shape how the doors look and work.
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.
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.
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.
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.
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.
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.
