History

The history of YTONG starts in 1923, in Sweden. Architect Johan Axel Eriksson at the Royal Institute of Technology in Stockholm managed to produce an extremely light weight material with superior insulation and fire resistance properties. The material was patented during 1924.

The licence for the production was granted in 1928 and contractor Karl August Carlen started the production of the aerated autoclaved concrete (AAC) in 1929. The first branded building material in the world combines outstanding insulating properties and easy workability associated with wood together with solid construction and rot and fire resistance.

 

The product was named Yxhult Anghardad Betong: “Yxhult” is a small Swedish town and “Betong” is the Swedish word for concrete. A short version of it though, became the famous brand today known all over the world as simply YTONG.

 

AAC has been successfully used in Europe since the 1920’s and in Asia since the 1960’s. In Europe, there are today more than 100 production sites in 18 countries producing around 20 million m3 of AAC per year.


Ytong aerated concrete is a brand of the century. 

Now, one of the strongest brands in the building materials market, that has long been a guarantee for the best thermal insulation and solid quality, also numbers among the premium group of top German products. At the same time it represents the culmination of an unparalleled period of development. In 1929 the first aerated concrete was produced in the Swedish town of Yxhult. “Yxhults Anghärdade Gasbetong”, gave birth a little later to the world’s first registered trademark for a building material, Ytong, which went on to change the construction industry for good.

 

In Germany, the rise of Ytong began during the years of reconstruction in the post-war period, but reached its zenith during the years of the economic miracle in the early sixties. Even as early as 1952, former Minister of the Economy, Ludwig Erhard, challenged the construction industry to use Ytong as a, “recognised good and modern building material”, that was furthermore comparatively inexpensive.

 

The rapidly growing acceptance of the material is closely linked with the introduction of the Ytong building block in 1960. This newly developed large format block offered unheard of dimensional accuracy at the time and could by used to construct an almost seamless wall using thin bed mortar. It permanently and fundamentally changed the traditional masonry techniques. The Ytong blocks have been sold wrapped in yellow plastic film since 1967. This yellow film is part of the marketing strategy that places the emphasis firmly upon brand recognition.
