What spans can glulam beams achieve?

Glulam beams can span significantly further than solid timber due to their engineered composition and available depths. Typical spans: straight beams 6–25 m (depending on loading and section size), curved beams 15–40 m (arches and portal frames), and tapered beams 8–20 m (pitched roof applications).

Typical spans: straight beams 6–25 m (depending on loading and section size), curved beams 15–40 m (arches and portal frames), and tapered beams 8–20 m (pitched roof applications). The longest glulam spans in practice exceed 100 m for arch structures (e.g., the Viking Ship sports hall in Hamar, Norway at 96 m span). For standard building applications, 8–15 m spans are routine with sections of 140–240 mm wide × 400–1200 mm deep.
