Crittall-Style Internal Doors: The Complete Aluminium Guide
Crittall-style internal doors add industrial elegance and light to any room. Learn how they work, glass options, sizes and cost for your UK home.
Crittall style internal doors have become one of the most sought after features in modern UK homes. That distinctive grid of slim black frames dividing panes of glass brings light, structure and a touch of industrial elegance to open plan spaces. Here is everything you need to know before you buy.
What are Crittall-style doors?
The name comes from Crittall, the original maker of steel framed windows and doors with their signature slim black grids. Today, aluminium versions capture that same look, thin dark frames arranged in a grid, but with the benefits of modern materials. Aluminium is lighter than steel, will not rust, needs no maintenance and is easier to make to measure, while keeping the crisp, minimal aesthetic.
Why homeowners love them
The appeal is both practical and visual. Because the frames are slim and the doors are largely glass, they divide a space without blocking light, so you can separate a kitchen from a dining room, or create a home office, while keeping the open, airy feel. The black grid is a design statement that suits everything from period properties to contemporary new builds. And unlike solid doors, they let you see through, which keeps a home feeling connected.
Glass and configuration options
You have plenty of flexibility. Doors can be single or double, with fixed side panels and top lights to fill a wider opening. The grid pattern can be adjusted, with more or fewer horizontal and vertical bars to suit your taste. Glass options include clear for maximum light, or obscured, reeded or fluted glass for privacy while still passing light through, which is popular for offices, bathrooms and bedrooms.
Sizes and where they work
Crittall style doors are made to measure, so they fit openings from a single doorway up to a wide room divider. Common uses include kitchen to dining room dividers, home office partitions, hallway to living room screens, and creating a broom cupboard or utility that still feels part of the room. Because they are internal, they do not need the weather sealing of external doors, which keeps the frames especially slim.
What do they cost?
Price depends on size, the number of panels, the grid complexity and the glass you choose. For current UK figures, see our dedicated guide on how much Crittall-style internal doors cost.
