Glulam is a high-quality material which is useful in a wide range of applications and possesses outstanding properties. It can be incorporated ideally in interior design and is particularly attractive.
Glulam – A high-tech product
The term glulam is understood to be components for wooden constructions that are made of technically dried spruce boards, from which flaws that reduce rigidity and visual defects such as large knots, pitch-pockets and ingrown bark have been removed. Elimination of the weak points and the layered structure result in the high-tech product known as glulam.
High dimensional stability
Normal construction timber continues to dry in its installation condition. It shrinks, distorts and warps. Solid wood 24 cm wide, for example, shrinks between 10 and 20 mm with a wood moisture content reduction from 30 % to 10 %. This can also result in the formation of cracks. The most frequent cause of leaks in external walls and the consequent damage caused by the moisture is the shrinking of timber that was installed when it was still too wet. During the manufacture of glulam, the lamellae are technically dried to approx. 12 % wood moisture content before gluing, and they are planed afterwards. The finished glulam thus already has a wood moisture content which corresponds to the equilibrium moisture in the installation condition.
Glulam exhibits substantially better characteristics than solid wood during processing. It will also not warp over the long term and the degree of cracking is minimized.Glulam is thus particularly suitable for visible components and the basis for a durable and dimensionally stable construction.
