Product description

Research project: Use of weak hardwood for the production of cross laminated timber

As a result of the near-natural and site-adapted silviculture, there has been a strong increase in hardwood supplies in Germany for some years. However, the share of material use of hardwood is steadily decreasing. A large proportion of deciduous wood, especially weaker wood dimensions and lower-quality wood, is used for energy purposes, which releases the CO2 components stored in the wood again. An expansion of the material use potential of hardwood is therefore urgently needed on the one hand to achieve the highest possible value added from the raw material wood economically and on the other hand to make a positive contribution to climate protection through the long-term binding of CO2 in wood products.

Hardwood species, such as the beech, are characterized by very high mechanical properties, but have a very low dimensional stability. A use as a construction material was therefore not, or only very limited, possible. In order to optimize the properties of deciduous trees with regard to swelling and shrinkage behavior, various methods of wood modification are used in this project. In conjunction with targeted bonding, the beech wood should meet the requirements of a BSP wall and find its way into constructive use.

Product innovations:

-Excrease the dimensional stability of deciduous wood by novel wood modification processes.
-The production of cross laminated timber elements (BSP), of deciduous wood and inferior wood qualities
