Glulaminated (Glulam) and Cross-laminated (CLT) timber offer distinct yet complementary approaches to crafting stunning and sustainable feature stairs.
Glulam is produced by layering smaller timber sections with their grain running parallel, resulting in long, strong beams or columns ideal for structural elements like stringers. Its inherent strength-to-weight ratio allows for long, unsupported spans, making it perfect for creating elegant, sweeping curves or dramatically straight feature stairs with minimal posts.
In contrast, CLT panels are made by stacking layers of dimensional lumber at perpendicular 90-degree angles and bonding them under pressure. This crisscross lamination offers high load-bearing capacity in both directions, making it suitable for solid, monolithic stair treads, risers, and landings. The prefabrication of CLT stair components off-site offers significant construction speed advantages and reduced on-site labor and noise.
Both mass timber products offer excellent fire resistance, aesthetic warmth, and a reduced carbon footprint compared to traditional concrete and steel, making them a premier choice for modern, eye-catching feature staircases
