YTONG thermal insulation blocks were created in order to provide all essential benefits of construction materials in one product: high level of thermal insulation, easy to cut and shape, fire resistant, sustainable and ecological. YTONG is a premium product, made of mineral and natural raw materials: lime, sand, cement, and water .
In 1929, the first autoclaved aerated concrete was produced in the Swedish town of Yxhult, under the name Yxhults Anghardade Gasbetong, from which the brand name YTONG was derived. Following the First World War, Sweden needed a masonry product with thermal insulating properties, easy to cut, shape and install and economical, in order to reduce the fuel consumption, as people had limited access to resources. Dr. Arh. Axel Erikson made the first attempt at autoclaving aerated concrete, that later on the world’s first registered trademark for a building material. YTONG, the name of the brand, is derived from: Yxhult, the place where it was invented, and Gasbetong, Swedish term for autoclaved aerated concrete. Germany adopts this product in the '50s.
In Romania, YTONG is the first masonry product to be included in the A energy efficiency class, without the need for additional thermal insulating systems for the facades.
Nowadays, YTONG systems include products for exterior walls, repartitioning, lintels, special mortar; all these being the basis of nearly zero-energy buildings.
