Pine wood is used for many purposes. A vital aspect of this is the quality and area of origin of the wood. Nowadays, pine wood is mostly imported from Scandinavia as a semi-finished product and sorted according to specific quality classes; in the Netherlands according to KVH2000. Applications include, among other things, floor boards, interior cladding, ceiling boards, facade frames, furnitures, door frames, profiles, heavy constructions, packaging, etc.
For exterior window frames, sapwood outside of the rails is not recommended. Due to its ‘open’ structure, the sapwood can be properly impregnated however. As a result, pine wood, if preserved, is also extremely well-suited for exterior purposes.
