Sustainable, ecological, and healthy
Duobalken® and Triobalken® are produced exclusively from softwood supplied from sustainably managed forests in Europe. A large proportion of the energy used for drying the wood comes from renewable sources. Being easy to process, the amount of energy required for processing is actually small. So it should come as no surprise that Duobalken® and Triobalken® have an outstanding ecological balance sheet.
Natural construction materials which have no harmful effects on health are a key precondition for contemporary construction projects. Duobalken® and Triobalken® are kiln-dried to a low level of wood moisture, enabling them to absorb humidity from the ambient air. They therefore contribute to a healthy ambient climate.
Compared to other construction materials such as steel or concrete, wood has a very low level of thermal conductivity. Duobalken® and Triobalken® in exterior wall or roof structures have low thermal conductivity, which reduces thermal bridges and makes energy-efficient buildings possible.
Given the particularly high level of thermal insulation in modern timber buildings, the shell of the building must be windproof and airtight. To achieve airtightness on the inside, the building components must be dimensionally stable when installed and, once fixed in position, they must not deform through shrinkage to any great extent as this would reduce the level of airtightness. Thanks to the method of cutting used, finishing to an exact fit and a maximum wood moisture content of 15%, Duobalken® and Triobalken® are suited for use in passive energy houses and energy-efficient houses.
The major advantages in terms of ecology and healthy living can also be found in the Product Declaration for laminated beams, published by the Institute for Building and Environment.
