Thermal Insulation Features of Residential Historical Buildings in the Case of Saint-Petersburg

摘要

Stiff requirements for power consumption in buildings made it necessary to keep historical buildings of Saint-Petersburg warm. The majority of buildings in the historical center of Saint-Petersburg are historical and cultural monuments under protection. Existing protective regulations do not allow any changes in front facades of buildings rich in architectural decorations. However, courtyard facades, as a rule, can be exposed to exterior changes. This gives grounds for different approaches to heat facades of historical buildings. The article mainly focuses on internal heating of front facades. A construction for heating exterior walls based on extrusion-type polystyrene foam panels has been suggested herein. A required thickness of insulating material has been determined and moisture regime for insulated and non-insulated exterior walls has been analyzed. Recommendations to choose constructions for internal insulation of exterior walls in historical buildings of Saint-Petersburg have been elaborated.
