Cross-Laminated Timber, or CLT, differs from Glulam in that the wood is glued up with each layer of boards being perpendicular to each other. Description The standardized bridge design aides in this publication are for superstructures manufactured with glued-laminated timber (glulam) that was pressure-treated with preservatives. glued laminated timber. When used in heavy timber construction, Glulam ensures high earthquake resistance and excellent resistance to aggressive substances. Glulam (glued-laminated timber) is an engineered structural wood product that consists of multiple individual layers of dimension lumber that are glued together under controlled conditions. Most, if not all modern wood-framed buildings use engineered wood products. The material is made up of several layers of structural timber that have been bonded together using adhesives in order to form a bigger, potentially enormous piece of wood. Glulam possesses many advantages such as high stability and strength, good fire resistance and favourable architectural properties. It is a way of manufacturing timber elements that cannot be easily sourced in solid timber due to their large size or unusual shape. Before gluing the timber blanks are thoroughly dry in the camera, which reduces their moisture content to 12%. We produce a broad range of Douglas fir glue-laminated timber products as well as high-quality lumber including western species studs and dimension lumber. Glued laminated timber production - is a long and interesting process. When large cross-sections are subjected to a fire a char forms around the outside of the beam that protects the core by restricting the oxygen supply.
