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 to precisely the height needed in construction. Glulam can be easily processed if necessary using various techniques. Drilling and milling is performed and incisions are made using a CNC machine, which ensures top of the line quality and precision.
