Glued laminated log is a structural timber product composed of several layers of dimensioned lumber (lamellas) glued together.
The layers of wood are dried to about 12% moisture content and then sorted by length. Some lamellas are made by end-jointing to the required length. The most common end-joint is a finger-joint. Structural glue is applied to end-joints and cured under pressure and heat.
Adhesive is applied, and the laminations are then assembled into the required lay-up so that the strongest heartwood is kept at the surface of the log. and put under the pressure.
After proper pressing and curing time, the glulam timbers are removed from the presses and then the faces are planed to remove adhesive that has squeezed out during pressing.
