puitmaterjalide

Wood materials, or puitmaterjalide, refer to products derived from trees used in construction, furniture making, and packaging. They cover solid lumber as well as engineered wood products such as plywood, oriented strand board (OSB), particleboard, medium-density fibreboard (MDF), laminated veneer lumber (LVL), glued laminated timber (glulam), and cross-laminated timber (CLT). Solid wood provides natural appearance and strength, while engineered woods offer improved dimensional stability and performance for longer spans and lighter structures.

Solid wood is typically categorized into softwoods (for example pine, spruce, fir) and hardwoods (such as oak, maple, birch). Engineered wood products are created by binding wood fibers, veneers, or strands with adhesives to produce panels, beams, or laminated members. Examples include plywood (veneer layers), OSB (wood strands), MDF, particleboard, LVL, glulam, and CLT, each with specific mechanical properties and common applications.

Processing and standards: Wood materials are dried or seasoned to a target moisture content to minimize deformation and improve strength. They are graded for structural performance or appearance and finished with coatings or treatments as needed. Environmental and health considerations influence the choice of adhesives and finishes, especially for interior applications.

Sustainability and end-of-life: Responsible forestry certification programs such as FSC and PEFC help ensure sustainable sourcing. Wood products can be reused, recycled, or repurposed, and engineered woods are often designed for long service life in both interiors and exteriors.

Applications: Used in structural framing, flooring, furniture, cabinetry, interior panels, wall and roof sheathing, exterior cladding, and packaging. Selection depends on load, exposure, moisture, and finish requirements.
