This series has its origins in the “Universal Range”, which was introduced for the first time in 1912 by the british company “The Crittall Manufacturing Co. Ltd.”. The Universal range consisted of three different ranges of profiles, identical in geometry and types, but different in their depth, that classified them into large, medium and small. Depending on the dimensions of the window, the most appropriate series was selected from a static point of view. These three ranges were able to cover any type of window and in combination with special T-profiles, used as mullions and transoms, for the first time it was also possible to realize curtain walls of any size.
The classic W40 range is an evolution of the famous W20 range developed in 1964. Produced for the first time in 1995 it consists of 18 profiles and follows the unmistakable classic design of its predecessor.
