The project ran between November 2020 and May 2021.
The aim of the project has been to confirm the hypothesis that boards sawn from residual products from CLT panels can be used to develop and increase the volume of advanced housing construction in wood. Aspects treated to achieve the goal mainly relate to material characterization and production-related issues.
Boards cut out from CLT-panel waste (e.g. door and window openings) have been produced at a pulp in Gruvön, Grums, and delivered to university for characterization, but also to three companies producing light frame volumetric elements for residential housing to study their performance in production. In both cases, the product exceeds the expected performance. The stiffness is higher and strength is 5-6 times higher than structural timber of quality C24 typically used today.
The companies involved in the evaluation of the product in a production environment reports very positively from the experience.
