A Profile Of The Glulam Industry
In terms of current needs to optimize products from a carefully managed timber resource, glulam is one of the most resource-efficient approaches to wood building products. It is an engineered product manufactured to meet the most demanding structural requirements. But glued laminated timber is not a new product.
100 Years Of History
The first patents for glulam were issued in Switzerland and Germany in 1900. A 1906 German patent signaled the true beginning of glued laminated timber construction. One of the first glulam structures erected in the U.S. was a research laboratory at the USDA Forest Products Laboratory in Madison, Wisconsin. The structure was erected in 1934 and is still in service today.
Advances In Exterior Applications
A significant development in the glulam industry was the introduction of fully waterproof phenol-resorcinol adhesives in 1942. This allowed glulam to be used in exposed exterior environments without concern of glueline degradation.
The first U.S. manufacturing standard for glulam was Commercial Standard CS253-63, which was published by the Department of Commerce in 1963. The most recent standard is ANSI Standard A190.1-02, which took effect in 2002.
