Glued laminated timber – Larch
Shortly after the start of the production of glulam, we also started to produce larch beams. Normally larch is used for external use because it is much more resistant than spruce.
Recently, we have been able to offer our customers the beams not only with the 33mm slats (service class 3) but also with the 40mm slats (service class 1-2).
The raw lamellas are technically dried to a wood moisture of about 12% (±2%).
In the subsequent grading process, strength-reducing or unsightly growth deviations such as large knots, resin pockets and bark inclusions are cut out and pushed into endlessly long lamellas with a finger-shaped, friction-locked adhesive joint.

The endless lamellas are then planed, glued and pressed.
The resulting glulam blank hardens under pressure and is planed to size and set.
The resulting beam can now be tied if desired by the customer, e.g. the installation of steel parts. Additionally the components can be provided with weather protection or wood protection and then packaged if desired.

Through drying, homogenisation and strength grading, a very dimensionally stable, crack-minimised product is created which has a higher bending strength than normal construction timber.
Glued laminated timber in larch has a very high durability and is therefore frequently used outdoors, e.g. in terraces, conservatories and balconies.
Due to the waterproof gluing, our product can be used in service class I (indoor area with room climate), service class II (outdoor area with increased air humidity but under roof) as well as service class III (outdoor area and freely weathered).

We manufacture glulam according to DIN EN 14080:2013 in the strength classes Gl24h and Gl28h.
They can be used in service class I/II and III alike. See tab areas of application for more details.
