LaNaSys

Development of a material- and energy-efficient timber construction system made of hardwood and softwood

Cross laminated timber usually consists of several layers of high-quality softwood; lower qualities or hardwood are rarely used. A shortage of softwood as a resource is to be expected in the future, with associated price increases. 
LaNaSys is working on the development of a CLT product in which juvenile hardwood of lower quality or waste wood rolls from veneer production are used in the middle layers. Today, both are usually thermally utilised or further materialised, which results in a qualitative devaluation and the carbon storage capacity of the wood is not fully utilised.
The aim of the project is to develop hybrid cross-laminated timber ceilings with dissolved centre layers. The integration of a fire-retardant layer made of Cottonid promises classification as a self-extinguishing component. Softwood is saved and less material is required overall compared to cross-laminated timber. This makes the system both energy and material efficient.
The result will be the pre-competitive development of the ceiling systems and a comparative analysis with conventional CLT in terms of application spectrum, material efficiency, cost-effectiveness and market potential.
