What is Glulam and what are its relevant properties?

• A. A metal alloy with high strength.
• B. Multiple pieces of wood glued together to give a better strength-to-weight ratio and easy shaping; CLT is sheet-based with strength in multiple directions.
• C. A type of ceramic tile.
• D. A glass fiber reinforced polymer.

Answer: (B)

Glulam is a timber product made by bonding together multiple pieces of wood along the grain to form a single structural member. By stacking and gluing laminations, it gains much higher strength and stiffness than solid timber, along with a better strength-to-weight ratio. This also allows long spans and even curved shapes that solid timber can’t easily achieve, making it versatile for beams, arches, and supports. Relevant properties include strong bending and shear performance along the grain, good dimensional stability, and the ability to tailor size, shape, and finish using different timber species and adhesive systems. CLT is mentioned for contrast: it’s sheet-based and provides strength in multiple directions due to cross-lamination, whereas glulam’s strength is mainly along the grain direction.
