The project involves the construction of a residential complex consisting of 2 multi-storey buildings and an underlying commercial area and is located in an important area of the urban city of Turin. GREI under floating screed was used for the impact noise soundproofing in the rooms.

Problem.

The owner needed to acoustically insulate the floors of residential buildings with low thickness products.

Suggested solution.

The Grei 5 product, in compliance with the acoustic and dimensional requirements, was suggested for this project. Obtained by recycling EPDM rubber with a thickness of only 5 mm, it guarantees excellent acoustic performance due to the high elasticity of the rubber used.

Result.

The technical requirements regarding the thickness and the acoustic performances according to the law have been respected with a level of Lnw footfall equal to 57 dB.
