International comparison of facades

At the beginning of the twentieth century (between 1910 and 1940), a new form of building envelope developed which was hitherto unknown – the transparent facade. The ideas came from architects such as Walter Gropius and Mies van der Rohe, who dreamt of transparent building envelopes for their buildings. What was initially a tentative movement gradually became the general trend. In the 1950s and 1960s, the construction of office buildings with facades was established and a very common occurrence. Today facades can be found in every city in the world. The construction of a high-rise building is almost unthinkable without facades.


Over the years different standard systems for facades have developed throughout the world, which are used to test and classify them. However, in recent years two “standard domains” have been established as “worldwide standards”, which are applied in many markets. On the one hand these are the American standard issued by AAMA, the American Architectural Manufacturers Association and ASTM, the American Society for Testing and Materials – and on the other hand, the European regulatory instruments such as those issued by the CWCT, the Centre for Window and Cladding Technology, and the CEN, the Comité Européen de Normalisation (European Committee for Standardisation). These two standard domains are used in many different continents for the assessment of glass facades. It is worth mentioning that there are even joint standards, also known as ISO standards (International Organisation for Standardisation), which are used in many standard systems worldwide.
