Open Source Wood challenge: Large wall panel connections

New Open Source Wood challenge is now open! The aim is to find a clever and practical way to connect LVL (laminated veneer lumber) panels into large sheets. Metsä Wood’s Open Source Wood is a platform developed to connect people and innovation in wood construction industry. We believe the only way to grow the use of wood in construction is to share knowledge.
