Glued laminated timber (glulam) is manufactured from softwood laminations 20–45 mm thick, finger-jointed and bonded in parallel or crossed arrangements. By distributing wood defects across multiple laminations, more homogeneous and load-bearing members are achieved compared to solid timber. Glulam can be produced in straight or curved forms, making it ideal for halls, bridges, and architecturally demanding structures. Strength classes (e.g. GL 24h, GL 28c) are regulated in EN 14080. Surfaces may be left visible or cladded. Glulam is a cornerstone of modern timber construction and contributes to CO₂ storage within buildings.
