Glue Laminated Timber (Glulam) is composed of individual wood laminations (dimension lumber), specifically selected and positioned based on their performance characteristics, and then bonded together with durable, moisture-resistant adhesives. The grain of all laminations runs parallel with the length of the member.
Glulam can be used in horizontal applications as a beam, or vertically as a column. Glulam has excellent strength and stiffness properties (pound for pound, it is stronger than steel - Glulam: Visible Beauty, Hidden Strength, APA – The Engineered Wood Association, 2012), and is available in a range of appearance grades for structural or architectural applications.
