This study examines the effects of wood types and impregnation (procedure types and process time) in performance of window frames corner joint with double tenon. For this purpose, "L corner joint" type samples (number 120) were manufactured by using Scotch pine (Pinus sylvestris Lipsky), oak (Quercus petreaea Lipsky) and black locust (Robinia pseudoacacia Polyvinyl acetate based (two kompenant-D4) adhesive were used to bond tenon and mortise corner joints. The samples were impregnated by using the method of immersion for 20 and 40 min with mixture of wax / linseed oil (3 % paraffin, 10 % linseed oil, 87 % white spirit) and imersol aqua. The diagonal compression test was applied to test samples (determine performance of the window frames corner joint) according to ASTM-D 143-83 1983 standards.
