Contribution of Site Orientation to the Seasonal Fluctuations of Wood Moisture Content in Wooden Windows

Durability of wood windows is especially important issue in times when energy efficiency, natural resources management and carbon cycle of products have great value. It greatly depends on several important factors: material selection, physical protection and detailing, surface protection, installation and regular maintenance. Moisture content and its distribution over the cross section of window frames directly influences dimensional (in)stability, particularly bowing and distortion. Therefore, the scope of this work was to monitor the distribution of moisture content of wood windows during one year period in order to get detailed insight into the influence of site orientation to the risk of degradation of wood.
