Study on the possibilities of increasing the effectiveness of thermal insulation of enclosing structures in window openings using low-emission coatings and films

This article discusses issues related to increasing the energy efficiency of buildings through the optimization of window structures and ventilation systems. The difficulties of analytical calculation of heat and moisture transfer in building envelopes are considered, and methodologies for research in this area are presented. Special attention is paid to the roles of window fillings and methods for reducing heat losses through window openings, such as the use of low-emissivity coatings and filling the space with inert gases. Methods for controlled air inflow through window structures without compromising airtightness are presented. The economic and practical aspects of implementing energy-efficient windows are discussed, and their contribution to the overall energy efficiency of buildings is evaluated.
