Project description

The project Adora Flatiron in the heart of Skopje is a striking residential building with a height of 60 meters with 16 floors- with 279 modern homes and luxirious penthouse apartments within a total surface area of over 23,000 m². This project was inspired by the famous New York building on Manhattan’s 5th Avenue Fuller Flatiron. The building has won the prestigious international award The Bizz 2016, in Monte Carlo, Monaco, from the World Business Confederation for Exceptional Innovation in Style and Quality of Housing and the National Award from the Ministry of Economy for Building Green Homes without eco and noise pollution, as part of the worldwide campaign for building green cities. With the installation of the high performance acoustic system solution of the Saint-Gobain materials-Rigips Blue Acoustic RFI system- this project raised the sound isolation criteria significantly above the standards. Thus, the interest of this project increased for the Saint-Gobain Trophy.

Key Challenges

One of the key challenges of this project was the certified laboratory measurement with the Saint-Gobain materials before the start of the project in the Insitute for Testing of Materials (IMS) in Belgrade, Serbia on December 15th, 2015. When offer was given to the contractor Ritam Trejd, laboratory measurement was performed and the results showed performance of Rw=55 dB (system made with 2 layers of Rigips Blue Acoustic RFI boards, Rigips profiles, Joint filler Vario and Isover Akusto 50) . Moreover, another key challenges was the acoustic comfort measurement after the installation of the Saint-Gobain materials on the project site by Geing Krebs und Kiefer International which showed acoustic performance index of R’ – R’w = 53.75 dB.
