What is a Crittall window or door?

You’ll best know Crittall windows and doors as designs in grid-like panels, however Crittall can refer to a range of steel-framed products. In everyday parlance, you may use Crittall to refer to any black framed steel window, door or internal screen; however, that’s not always entirely accurate. Crittall is a registered trademark, so only those steel frame windows and doors made by Crittall can actually be called by that name. While you shop around, you may see terms such as ‘Crittall style’ or ‘Crittall type’, which are likely to not be genuine Crittall products.

Crittall was founded in Braintree, Essex, and has been in operation for over 160 years. Where windows were traditionally made from timber at this time, it had great success in introducing steel windows into circulation, with Crittall windows used in the likes of the National Gallery, the Houses of Parliament and the Tower of London.

Crittall windows became most synonymous with the Art Deco and Modernist architecture movements from the 1920s. While this style may have fallen out of fashion for a period of the time since, in recent years they’ve become a much sought after style for contemporary homes.

Are Crittall windows practical?

Crittall frames are galvanised, which permanently seals them against rusting and warping when exposed to the elements. As they are powder coated, they won’t need to be painted on site either, ensuring an easier install and that they won’t need to be redecorated for 25-30 years.
