03 KIELSTEG construction element KIELSTEG construction elements… ... are lightweight, strong construction elements made of wood, with a linear cellular structure, which are used to make horizontal structures – structural floors and roofs –with wide clear spans. They use strips of timber to form top and bottom flanges, which are connected by curved webs of plywood or OSB. The name comes from the characteristic curve of the webs inside the elements, which resembles the cross section of a boat’s keel. The system concentrates material exactly where it is needed for optimal load-bearing. Bauen mit Kielsteg bedeutet: o Flexibilität erhöhen…….. Material reduzieren………. Nachhaltigkeit fördern Building with Kielsteg means: Improving the flexibility of use of the building, saving material and promoting sustainability. Certificates The European Technical Assessment regulates the manufacturing and use of Kielsteg elements in the member states of the European Union as the basis for the CE certification mark. Environmental Product Declarations (EPD) provide the data for environmental assessments. They enable meaningful comparisons of building materials in systems, or in whole buildings, over their whole life cycle … from cradle to grave. PEFC, the Program for the Endorsement of Forest Certification Schemes, is a certification and labelling program for products derived from ecologically, economically and socially sustainable forestry – covering the entire processing chain. When customers buy products with the PEFC label, they can be sure that their purchase supports environmentally friendly forestry. Kielsteg construction elements
