Our official representative for the Leningrad Region has shared successful results of the restoration work on a historical estate in the settlement of Levashovo, Leningrad Region, which began back in the autumn of 2025.
The work was complicated by the region's capricious weather conditions and the status of the site itself — any solutions that would alter the geometry or create a load on the structure were excluded a priori.
This is an estate from the late 19th — early 20th century — a living embodiment of history, requiring a rejection of inertial thinking in construction. We must openly admit: the use of traditional insulation materials on such objects is "architectural suicide". Attempting to use mineral wool or expanded polystyrene would literally "bury" the unique facade aesthetics, forever erasing the authentic brickwork and finest stucco from the cultural landscape. Also, classical systems create a colossal additional load on the old historical foundation, leading to irreversible deformations. Therefore, Bronya modifications proved to be an excellent solution for restoring the historical appearance and imparting energy efficiency to the building. The outstanding thermal insulation properties of the coating allow 1 millimeter of Bronya material to replace 50 millimeters of mineral wool, providing excellent thermotechnical performance without the slightest interference with the architectural appearance.
The work began in the autumn of 2025 with the application of "Bronya Facade NF". With its help, the entire facade of the house was treated, including all white decorative elements (platbands, cornices, and rustications) and the foundation slab. To preserve the original color of the facade, the material was tinted in brick-red, while the decorative elements were applied without change.
After successfully surviving the St. Petersburg winter, the customer appreciated the thermophysical effect of using liquid armor. Heat loss critically decreased, and the treated areas of the facade remained impeccably dry and warm. Inspired by the result, the client decided to scale up the thermal insulation effect. In the summer of 2026, the work was continued. For additional insulation of corners and wall joints, a highly effective combination of materials was used:
-
"Bronya Facade NF": Applied to the foundation slab, facade, and white decorative elements. This made it possible to combine a powerful thermal barrier with the highest vapor permeability, ensuring that the building's enclosing structures would "breathe", completely eliminating the accumulation and condensation of moisture inside the walls.
-
"Bronya Classic NF": Applied locally at critical points — corners and wall joints — where it was necessary to completely eliminate "cold bridges" with maximum film formation (non-vapor-permeable). This created a reliable hydrophobic barrier against slanting rain and through drafts at the building's most vulnerable junctions.
The completion of the project in the settlement of Levashovo is a triumph of technology over time. The updated appearance of the estate is impeccable. Thanks to the flexible tinting of the material, the very classical contrast of noble red brick and snow-white decor, as conceived by the architect over a century ago, has been preserved. Now the building is not just "renovated" — it is reliably protected from the aggressive climate. Our materials have shifted the dew point beyond the wall structures, eliminating internal moisture crystallization, which is the main cause of destruction of ancient brick.
Thanks to Bronya coatings, the preservation of historical appearance no longer conflicts with energy efficiency requirements. The use of ultra-thin polymer Bronya coatings on cultural heritage sites is not just a technological choice, but a strategic standard that determines the longevity of architectural monuments. We give history a future, without changing a single detail in it!
