Abstract :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 insert ignore into journalissuearticles values( Fagus orientalis L.);,  scotch pine insert ignore into journalissuearticles values( Pinus sylvestris L.);, sessile oak insert ignore into journalissuearticles values( Quercus petraea L.);, and poplar insert ignore into journalissuearticles values( 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 insert ignore into journalissuearticles values(89.17%);, PVAc-D 4 adhesive insert ignore into journalissuearticles values(89.79%); and control samples insert ignore into journalissuearticles values(88.69%);. In the interaction of the wood materials and type of adhesive, the highest value was measured in poplar+PUR insert ignore into journalissuearticles values(90.93%);, interaction of the wood materials and heat treatment in poplar + control samples insert ignore into journalissuearticles values(90.87%);, in the interaction of the type of adhesive and heat treatment in PVAc-D 4 + 185 °C insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(93%);, while the lowest in laminated scotch pine samples with MF and heat-treated at 185 °C insert ignore into journalissuearticles values(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.
