EPiC database - Glued laminated timber (glulam)

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.

Glued laminated timber or glulam is a structurally engineered timber product produced from large strips of graded timber that are bonded together. Glulam has a high degree of dimensional stability, and a high strength to weight ratio compared to steel.

Timber members are individually selected for lamination, to maximise strength and performance. Because of this, glulam can be manufactured with increased strength in particular areas, to compensate for areas of high stress in a structure. Synthetic resin glues are typically used as a binding agent, commonly in conjunction with finger joints to increase joint performance.

Glulam can be used for long structural members, which exceed the capabilities of standard timber. It is also used for columns, rafters, trusses and curved beams.
