As a result of the exacting architectural requirements in the construction industry and the trend to environmentally friendly building, glued laminated timber has experienced a tremendous upswing over the last year.
In all applications where a good dimensional stability and accurate dimensions – combined with cost-effectiveness and an elegant appearance – are important, glued llaminated timber can pick up points in comparison to solid wood.
The rigid connection between the individual wooden boards brings about components that have much better technical properties than solid wood. Large areas and exacting static requirements can be realised with glulam timber in the form of special components.
High-tech meets handicrafts
We attach great important to control systems and quality checks: At the start of the process, the boards, also referred to as lamellas, are checked on the basis of strength and surface criteria by means of state-of-the-art X-ray and laser technology.
Furthermore the timber moisture of every board is tested. After defects have been removed, the sorted boards are finger-jointed, planed, glued and pressed into finished components by means of a high-frequency press. Then they are planed on all four sides to finish. A final manual quality check ensures that each individual board that leaves the works is in perfect order.
