The history of YTONG starts in 1923, in Sweden. Architect Johan Axel Eriksson at the Royal Institute of Technology in Stocholm managed to produce an extremely porous 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.
