Wooden Window Structure and its Thermo-Humid Mode

Abstract:

Frame of window and all its parts are constantly evolving, trying to meet newrequirements, incorporating new materials and design approaches. Along with all of these,experimental research goes on. Complexity of problems varies based on various factorsand material structure reflects under certain circumstances negative aspects of the design. Thisarticle is dealing with appearance of condensation and icing in functional gap of wooden windowframe where we can see the most significant impact on it. Root cause analysis of condensationand icing has been conducted, factors leading to forming of condensation and icing have beendescribed in detail along with humidity characteristics of gap between particular parts of frame.Theoretical analysis is based on the real life scenario measurements conducted in various R&Dplants across Slovakia and Europe region. Article outlines next steps for a future researchconsidering window sealing and optimization of diffuse characteristics. Based on these we assumethat by incorporating of the diffuse characteristics knowledge and its optimization we achievea decrease of condensation and icing forming in functional gap of wooden window frame.
