The filming work of windows of City Residence apartment building was done in collaboration with the building developments as well as construction company. The problem appeared during sunny days when sun overheated the facade glass panels. The developer had already chosen very specific windows, which were supposed to resist heat while also being soundproof in conditions where planned windows were larger than usually. However, it still appeared that the sunshine period was longer and therefore the windows were not able to resist enough heat. When choosing the product, we performed a technical analysis to provide the client with data on what would happen once the windows are filmed. As a result of the filming, the temperature on the inside of the glass was reduced by five degrees. Thanks to that the indoor climate of the apartments imroved significantly. We used a boomlift for the duration of installation. Filming work was ordered by Endover Kinnisvara and Metropoli Ehitus.
