best wood DUO-/TRIO-BEAMS/ LAMINATED BEAMS For the highest requirements

best wood DUO-/TRIO-BEAMS/ LAMINATED BEAMS are particularly dimensionally stable. With only a few glued joints, the solid wood character is retained and the visible quality is high.

Only Scandinavian spruce from PEFC-certified mixed forests is used for the visible quality of the laminated beams. The visual quality and high strength are, in our opinion, the best that is currently possible in spruce.

Due to the high dimensional stability and the low wood moisture, best wood DUO-/TRIO-BEAMS/ LAMINATED BEAMS are particularly suitable for timber house construction. The low moisture content of the components means that preventive chemical wood preservation is not necessary, provided the design rules of DIN 68800-2 are observed.
