ANALYSIS OF WATER VAPOUR CONDENSATION IN GAP BETWEEN CASEMENT AND WINDOW FRAME OF WOODEN WINDOWS

摘要

The paper deals with thermal-moisture performance of a wooden window in standard external and indoor climate conditions in a gap between casement and window frame. Condensation or ice coating in the gap is the main problem of wooden windows. Thus, destructive processes on the wood surface finish causing the moisture penetration into the wood occur. The surface condensation is sufficiently covered by the requirements in currently valid standards. The condensate generation in the gap is not described neither limited by the standards nor regulations. The frequent problem occurrence in practice is to be dealt with and solved. The experimental and computing investigation was carried out using four types of MIRADOR 682, 682T, 783, 923 euro-profiles. For computing investigation the ANSYS programme was applied.
