Project description:

Mariinsky Theatre is one of the most famous and largest theatres of Opera and Ballet in the world, the center of cultural life not only in St. Petersburg, but also throughout Russia. Reconstruction of the second stage of the Mariinsky Theatre in St. Petersburg has become one of the most significant and talked about architectural projects recently. The new building of the Mariinsky Theatre is the most modern and technically equipped building, which meets world-class of public buildings.

Besides IGUs with silk-screen printing  for facade glazing, laminated glass with electric heating was used in this project in order to remove snow and ice on canopies. Our engineers have calculated loads. As the result, to reduce the overall weight of construction, innovative material SentryGlas was applied for the lamination, which enabled to reduce the thickness of laminated glass while maintaining given load-bearing capacity.


Among the problems to be solved for this project were the large sizes of laminated glass with heating, as well as point fixed system and the requirement to follow the architectural style due to the presence of open edges.

In order to control the heating of glass, we made the individual technical and design specification, as well as automatic control system. Heating control is carried out with the help of precipitation and temperature sensors. At precipitation appearance and air temperature within the specified range, automatic switch-on of heating system happens.

In operation, the sensors monitor the temperature on the surface of the glass, maintaining the optimal value , sufficient to remove the snow and prevent overheating. Switch-off happens automatically by a signal from the precipitation sensor. The automatic control system ensures safety during operation.

Using the touch screen and user-friendly interface client can manage heating by himself, changing the required parameters.

This project is an example of using such product with electrical heating function, where the company provides a "turnkey " solution – from project design for the given conditions to fully automated control system .
