Project goal: The implementation of the project by the building area includes the following technological stages: Facade insulation: with modern thermal insulation materials (mineral wool or polystyrene foam of appropriate thickness) followed by the application of a reinforcing layer and decorative plaster. Thermal modernization of the mountain ceiling: Since a significant part of the heat is lost through the roof, it is planned to lay a layer of insulation in the attic with the arrangement of vapor and waterproofing. Arrangement of an insulated basement: Protection of the foundation from freezing and moisture by installing extruded polystyrene foam below and above ground level. Replacement of windows: Installation of new energy-efficient metal-plastic double-glazed windows in places where old structures do not provide tightness. Related works: Restoration of slopes, replacement of ebbs and arrangement of a blind area around the building for rainwater drainage.
