Abstract	ABSTRACT Composite materials manufactured from wood with different adhesives are being used increasingly in the construction of furniture frames and buildings. In this study, LVLs were manufactured from pine ( Pinus sylvestris L.), poplar ( Populus tremula L.) and mulbery ( Morus alba L.) veneers with phenolformaldehyde (PF), polyvinyl acetate (PVAc), Desmodur-VTKA (D-VTKA) and urea –formaldehyde (UF) adhesives. Dimensional stability of LVL were measured after being exposed to steam for 2,6,12,24,48 and 96 hour-period according to the procedure of the Turkish Standards (TS) 3639. As a result, the highest density was determined for LVL with PF adhesive in all wood species. The highest weight increment as 113 % for poplar control , the highest radial swelling as 7.99 % for mulberry control, the highest tangential swelling as 5.7 % for mulberry control and the highest longitudinal swelling as 0.58 % for mulberry LVL with PF and PVAc adhesive were determined after being exposed to 96 h steam. Mulberry wood and VTKA and UF are proposed to manufacture of LVL used in damp condition
