This study was performed to determine the effects of heat treatment on weight loss during combustion of the laminated wood materials produced from Oriental beech (Fagus orientalis L.), scotch pine (Pinus sylvestris L.), sessile oak (Quercus petraea L.), and poplar (Populus nigra L.) veneers bonded with PVAc-D-4, PUR and MF adhesives. For this aim, the weight loss during combustion of the test samples was determined according to ASTM E 160-50. The results of this study indicated that the weight loss percentage was the highest in poplar wood (89.17%), PVAc-D-4 adhesive (89.79%) and control samples (88.69%). In the interaction of the wood materials and type of adhesive, the highest value was measured in poplar+PUR (90.93%), interaction of the wood materials and heat treatment in poplar + control samples (90.87%), in the interaction of the type of adhesive and heat treatment in PVAc-D-4 + 185 degrees C (91.10%). In the interaction of the wood material, type of adhesive and heat treatment temperature, the highest value was determined in laminated control poplar samples with PUR adhesive (93%), while the lowest in laminated scotch pine samples with MF and heat-treated at 185 degrees C (81.83%). The use of laminated and heat-treated wood material in places where in high risk of fire, impregnation of wood material with fire-retardant compounds can be suggested.
