Is glulam stronger than solid timber?

Yes. Glulam achieves higher and more consistent strength than solid timber because manufacturing defects (knots, grain deviation) are distributed across multiple laminations rather than concentrated in one location.

Yes. Glulam achieves higher and more consistent strength than solid timber because manufacturing defects (knots, grain deviation) are distributed across multiple laminations rather than concentrated in one location. A GL24h glulam beam has equivalent bending strength to C24 solid timber but with significantly higher stiffness and reliability, plus the ability to achieve much larger cross-sections.

Why this matters

This question relates to BSH Glulam Beams: Span Tables, Load Capacity & Specification Guide, which covers the broader topic in detail. Understanding this specific aspect helps architects, builders, and timber dealers make informed specification decisions.
