Bouwhout

Bouwhout is timber intended for construction projects, including structural elements such as beams, joists, planks, boards, and battens. It is distinguished from furniture wood by its intended use, grading, and moisture content. Bouwhout is typically softwood, mainly species like pine, spruce, or fir, though certain hardwoods are used for specific finishes. It is sold in various sizes and strength classes and may be dry or green, with moisture content influencing its suitability for different applications.

In Europe, structural bouwhout is described by strength classes (for example C14, C16, C24) and must meet standards that govern mechanical properties, grading, and quality. Common references include EN 338 for softwood strength classes and EN 14081 for timber grading and performance. Timber can be untreated or treated for durability, and it may receive preservative or fire-retardant treatments depending on the application and local building codes.

Uses of bouwhout include load-bearing frames, floors, roofs, and timber facades, as well as non-structural elements in buildings. For exterior or high-moisture zones, treated timber or engineered wood products may be chosen to improve longevity. Sustainability considerations are increasingly important; certified forests and chain-of-custody schemes such as FSC and PEFC are common in the supply chain.

Handling and storage practices emphasize keeping timber dry, off the ground, protected from weather, and acclimated to site conditions to minimize warping, cracking, or distortion. Defects such as knots, splits, or excessive moisture content are taken into account in grading and selection.
