puidumaterjali

Puidumaterjali refers to materials derived from wood that are used in construction, furniture, and manufacturing. It encompasses both solid wood and engineered wood products. Solid wood includes boards and structural lumber produced from harvested trees, while engineered wood comprises plywood, oriented strand board (OSB), particleboard, fibreboard, and structural products such as glulam (glued laminated timber) and cross-laminated timber (CLT), as well as laminated veneer lumber (LVL).

Key properties of wood materials include a high strength-to-weight ratio, anisotropy (mechanical properties differ along and across the grain), natural moisture sensitivity, and good thermal and acoustic insulation. Densities vary by species and moisture content. Drying to target moisture content reduces dimensional changes and decay risk. Durability depends on species, heartwood presence, and protective treatments; coatings and preservatives extend service life in exposed or ground-contact applications.

Processing typically involves harvesting, milling, and drying, followed by finishing. For engineered products, adhesive bonding and pressing create increased strength, stability, and uniformity. Wood can be shaped, cut, joined, and finished in numerous ways to meet design requirements.

Common uses include structural framing, flooring, wall and roof panels, furniture, and interior fittings. Engineered wood enables longer spans and larger panels with efficient material use, contributing to flexible design options.

Sustainability considerations: wood is a renewable resource when sourced responsibly and can store carbon during use. It generally has lower embodied energy than many other construction materials. Certification schemes such as FSC and PEFC help ensure sustainable forestry. End-of-life options include reuse, recycling, and energy recovery. Limitations include susceptibility to moisture, decay, and insects if not protected, and the need for appropriate fire and moisture protection in some applications.
