The paper analyzes the thermal properties of the modern PVC windows in winter. According to the methods of existing regulatory documents, the selection of the PVC windows for several climatic regions (for Moscow, Rostov-on-Don, Novosibirsk) was made. The windows selection was made on the basis of ensuring their normalized heat transfer resistance. To assess the thermal performances of the PVC windows, numerical calculations of two-dimensional temperature fields were performed at different design outdoor temperatures (for the considered cities). The analysis of the humidity of the internal air was carried out to ensure the thermal protection requirements. Additionally, laboratory tests of these window in the cli matic chamber were done were carried out at negative outdoor temperatures (-5; -15; -25; -35; -45°С). Laboratory tests have shown that at negative outside temperatures there is a significant decrease in the thermal characteristics of PVC windows due to the temperature deformation of their profile elements. The identified effects are currently not taken into account in the design.
