In Eastern and Western Europe, many AAC plants successfully supply both AAC blocks and AAC panels. Japan until today, remains a 100% reinforced elements market (fig. 5). Since 2002, reinforced element production was further perfected by the Dutch and nowadays Aircrete Europe’s technology allows manufacturing complete prefab AAC building solutions. Taking into consideration fast, economic and structural building with AAC panels, many countries today are looking for ways to introduce complete AAC building solutions in their local construction markets.
Mergers & Acquisitions
Mergers and acquisitions wave of the 1990s has had a crucial impact on the world of AAC as we know it today. In the period between early 1990s and early 2000s, ownership of technologies, plants and brand names became disoriented. Plants, patents, technologies and patents of Durox, Ytong and Hebel ended up under one roof and named Xella. At one point,Hebel and Durox products were produced under the brand name Ytong, as all three brand names were unified under the name Ytong. In 2001, a range of factories were closed under the premise of overcapacity.Many AAC technology specialists lost their jobs. Hebel took the biggest hit as their main base in Emmering, Germany was closed, and some Hebel facilities were liquidated, stating that production costs became too high. The market of architects, builders and especially the end consumers could not understand the disappearance of the well-known brands. Following this, the brand “Hebel” was reinstated as a brand for the reinforced products, while Ytong remained a brand for blocks. Furthermore, not a single Durox plant was closed throughout AAC’s history and AAC is produced until now in the remaining plants as well as the original Durox based plants.The period was an exodus of know-how in AAC world and many licensees had to fi nd their own way in the world of AAC.
