Product impact



Bronsø thermally treated wooden cladding is upcycled from of discarded material from a regular production of wooden goods. Sorting criteria today means substantial amounts of material is discarded, despite its high quality. The wood is discarded due to knots, checks and other natural tree characteristics, which has no impact on the durability of the wood. These 'mistakes' means the wood is normally sent to a waste management facility for incineration, despite the woods' high value.
