About Xella
Headquartered in Duisburg, the Xella Group develops, produces and distributes building materials and insulation products based on mineral raw materials. With the brands Ytong and Hebel (autoclaved aerated concrete), Silka (calcium silicate blocks) and Multipor (non-combustible mineral insulation boards), the company ranks among the largest manufacturers of autoclaved aerated concrete and calcium silicate blocks worldwide. In addition to its building materials, Xella offers blue.sprint, a digital planning service based on a digital twin according to the open BIM standard (IFC), which enables more efficient planning of material requirements and saves resources. The company is present in more than 20 countries with 56 plants and operates its own technology and research center with locations in Emstal and Brück (Brandenburg).
