MYRIAD by SANA Hotels is a 5 stars luxury hotel linked to the icon Vascoda Gama Tower, located at Parque das Nações in Lisbon. Based on the commercial partnership agreement, the CDM solutions were chosen once again to guarantee noise and vibration comfort conditions in another SANA hotel.

Located at Parque das Nações, a leisure, commercial and residential new district in Lisbon, the 5 star hotel ‘MYRIAD by SANA Hotels’b was executed in two concrete structure parts and glass surfaces with 142 m height. The building is connect to the existing Vasco da Gama Tower, a metal structure tower inaugurated in 1998 during the universal exposition in Lisbon, EXPO 98, an emblematic structure during the exposition but also actually a national icon.

To isolate the technical rooms at 2nd, 21st and 23rd plants, several CDM-MONT-100 concrete slabs 100 mm thick with a natural frequency < 8 Hz were installed.

Besides this application, all concrete floor in the hotel were isolated with underscreed solution CDM-MTC-4,5.

A Jacuzzi and a swimming pool  located in the 22nd plant were also acoustically isolated with special CDM-POOL system.
