The effectiveness of facade systems
The article discusses the results of studying the thermotechnical properties and energy saving factors of insulation systems based on mineral wool products and products based on extruded polystyrene foam under conditions close to natural ones. The studies were carried out on the basis of the hypothe...

The article discusses the results of studying the thermotechnical properties and energy saving factors of insulation systems based on mineral wool products and products based on extruded polystyrene foam under conditions close to natural ones. The studies were carried out on the basis of the hypothesis according to which the heat-saving characteristics of the facade insulation systems are most dependent on the thermal resistance along the surface of the wall, on the thermotechnical uniformity of the insulating sheath and on the stability of the properties of the heat-insulating materials under real operating conditions. The implemented complex made it possible to establish that the smallest difference between the air temperature in the room and the surface temperature in the lower zone was achieved on a fragment of the building envelope with a mounted facade system with XPS as insulation. For the same type of facade system, the maximum heat transfer resistance in the lower zone of the building envelope was reached - 2.72 m2 ° C / W for the cold period of the year, which significantly exceeds the characteristics of the system of mounted ventilated facades with mineral wool thermal insulation in the corresponding zones. The factor of “additional warming” from the soil, which is used to justify the rejection of warming in the buried part of the structure, does not work in the cold season.
