XC® components are pre-fabricated, large-format and standardised panel-shaped timber concrete composite elements for structural civil engineering purposes. For instance, this hybrid is used for high-quality floors and partition ceilings in multi-storey residential and office buildings. XC® combines the properties of both perfectly: Cross-laminated timber – which is also available in visible quality – takes care of the tensile forces that occur in the structure's lower cross-section, while the concrete absorbs the compressive forces in the upper. As a building element, the XC® by MMK timber concrete composite element bridges large spans with an improved vibration behaviour and good sound insulation values. Its high degree of industrial prefabrication and flexible dimensions allow for fast and dust-free installation at the construction site.
XC® by MMK timber concrete composite elements were developed by Mayr-Melnhof Holz in cooperation with Kirchdorfer Fertigteilholding and are produced by their joint venture MMK Holz-Beton-Fertigteile GmbH.
