Glue laminated construction(glulam) products are large manufactured structural products used in commercial and residential applications. The idea of laminating lumber with glue for use as beams was originally conceived on job sites in Europe over 100 years ago. This engineered wood product is composed of multiple laminations of kiln-dried, end-to-end or finger-jointed lumber, each bonded together with phenolic resin, a high-strength waterproof adhesive. This process allows for longer and wider structural wood members.
