Studies on Some Properties of Quality and Performance in Wood Windows

Tuncer Dilik and Barış Altun


The determination of some quality and performance properties of windows, made of tree species used frequently in industrial window manufacturing and the effects of tree species on those properties have been examined. According to the results of the study by considering regular standards, in the air resistance tests, the classification has been determined as follows: those made of Scots pine as (Pinus sylvestris) A4, European larch (Larix decidua) as A3 and Sapele (Entandrophragma cylindiricum) as A2. The water resistance test has classified those made of Scots pine (Pinus sylvestris) as in between RA6 and RA7, European Larch (Larix decidua) as in between RA1 and RA3 and Sapele (Entandrophragma cylindiricum) as RA1. As for wind resistance test, all species have been found in the class W5. When having made the same test in PVC for the purpose of controlling and making comparison and to verify the outcomes obtained from regular test, it was found that air permeability was A4, water tightness was RA9 and wind resistance test was W5. As can be seen from the given results, PVC has proved to show best performance among all, whereas Scots pine samples has shown the the best performance among all the other wood products followed by European Larch and Sapele. The reasons for that are the woodworking and workmanship quality rather than changeable physical, mechanical and technical properties of the wood species.
