Glued Laminated Members
Glued laminated timbers were used as early as the late 1800s. During and since World War II, they have been used extensively. Casein adhesives were the most frequently used until the early 1970s, when they were generally replaced by synthetic resins suitable either for exterior or interior use. Glued laminated members (glulams) have seen increasing use in both buildings and bridges. Structures that would not have been feasible using only sawn-timber members have proved practical and successful using glulams.
