Crittall Style Doors

crittal doorsCrittal doors typically feature square or rectangular panes of glass, divided by slim metal frames. These are the classic art deco windows seen on many London buildings from the 1920s - 1930s. They have a minimalist, industrial look and are often used internally and externally to divide spaces while still letting through plenty of light.

The name “Crittal” comes from Crittall Windows Ltd, a company founded by Francis Henry Crittall in 1884. The company was originally based in Braintree, Essex, and was renowned for manufacturing steel-framed windows and doors.

Crittall Windows rose to prominence in the 1920s and 1930s, becoming widely associated with modernist and Art Deco architecture during that period.

Crittall windows and doors are again becoming increasingly popular in London homes due to their sleek, modern design and ability to maximise light in smaller spaces. This classic style blends extremely well with local architecture throughout London and the South East. Also, because the style and materials originated nearby in Essex, installing this style of industrial heritage windows enhance your property and maintain strong ties to British design.

Minimal Frame Projects offers a full range of Crittal-style windows and doors for both internal and external use. While retaining the classic British style, the updated aluminium frames provide you with all the benefits of thin, lightweight construction, enhanced security, and high thermal insulation.

Our modern aluminium Crittal windows and doors are custom made to your specifications. They are available as fixed windows, single/double sash, top-hung, tilt & turn, pivot windows, bifold doors etc... the list goes on.
