Structurally flexible glulam
Glulam (glued laminated timber) is produced from timber that has undergone a technological drying process and generally contains 12% moisture. By laminating the layers together with adhesive, glulam can be produced at precisely the height needed in construction.
Glulam can be easily processed, if necessary, using various techniques. Drilling and milling are performed and incisions are made using a CNC machine, which ensures top-of-the-line quality and precision.

Special shapes of glulam beams
The special shapes of glulam beams significantly expand the options for designing and constructing building structures, ensuring optimal solutions for different building types. Regular beams can reach a maximum length of up to 36 metres, while trusses can be even longer.
