The fire retardant treated and untreated plywood and alder wood samples were prepared with the aim to investigate the effects of the way of treatment on the combustion properties. Alder wood was used for the preparation of plywood. Boric acid and borax were used as fire retardant. The plywood samples were impregnated by using three different methods; first group samples were impregnated by soaking of individual veneer before manufacturing plywood. The second group samples were impregnated by adding boron compounds into the glue mixture and third plywood group samples were vacuum impregnated according to ASTM D 1413-88. In addition, the solid alder wood samples were impregnated with same fire retardant solutions for control purpose according to ASTM D 1413-88. The results showed that the most effective way of the treatment was the impregnation of plywood panels treated with boric acid and significantly reduced burning of plywood and solid wood samples.
