Glulam ceiling beams are made of DUO/TRIO glued beams with a tongue and groove profile. Due to the glue line which is invisible from the bottom side, the gluelam ceiling beams are form stable and the solid wood appearance is maintained. The relatively small elements are easy to be installed. This is a big advantage on reconstruction of ceilings in old buildings, when there is no possibility to pass through the roof.
