EXAMINATION OF THERMAL INSULATION OF EXTERNAL WALLS USING THERMAL IMAGER

One of the most important ways to increase the thermal and energy efficiency of buildings is to improve their thermal insulation. Thermal insulation of external walls is relevant not only for climatic conditions with a cold period of the year, but also for climatic regions with increased heat input into the premises. At present, the insulation of external walls with placing of cladding on some distance from the wall (ventilated facades) is increasingly used to improve the thermal efficiency of the enclosing structures of buildings intended for various purposes. Using of thermal insulation of external walls with placing of cladding on some distance from the wall allows to get significant reduction of energy costs not only for heating buildings in winter, but also for their cooling during the summer period of the year. It is most expedient to check the effectiveness of thermal insulation with the use of thermal imaging equipment. This allows us to obtain actual data on the thermal radiation of the enclosing structures. As part of thermal imaging survey of the building's facade is determined the heat-and-energy efficiency of the made insulation of the enclosing structures was determined. Also areas with increased thermal radiation due to the poor quality of the heat-insulation works were identified. As a result of the thermal imaging survey, the assessment of the thermal energy efficiency of the insulation with placing of cladding on some distance from the wall was made, and areas with increased thermal radiation were identified.
