Glulam (glulam) consists of at least three technically pre-dried board layers, which are glued flat and parallel to the fibres. In contrast to laminated timber, the individual timbers lie on top of each other. It is made of coniferous wood. The glue content in the finished product is very low and low-formaldehyde adhesives are used to prevent any impairment of the air quality in the room. Due to the multi-layered structure, cracking is significantly reduced and the load-bearing capacity is improved, which makes larger spans possible. Binders made of glulam, better known as glulam beams, can also be produced in larger cross-sections and a wide variety of carrier shapes. Today's manufacturing technology even allows a three-dimensional curvature of the beam to be produced. Glulam beams are often used for cantilevered purlins, but also for long-span hall constructions.
