High impact sound insulation is achieved thanks to the installation of a CDM-FIX decoupling system under this sport floor.
Nautique Living is a modern student complex with 403 brand new independent student rooms with private bathroom and kitchen. The complex also includes a number of common areas such as a lounge, laundry and private dining room. A sports field has been realised on the roof of the complex.
To prevent nuisance in the rooms – when using the sports field (jumping, ball sports, etc.) – a floating floor construction has been developed on the roof floor. On the roof floor a number of concrete blocks are installed on which a steel construction is laid. On this steel construction, a steel slab concrete floor is poured. Between the concrete blocks and the steel construction vibration isolators are installed with a sufficiently low resonance frequency of approx. 10 Hz.
Because the steel structure had to be anchored with a bolted connection, the CDM-FIX system was used, which is composed of a number of high-quality natural rubber elements (type CDM-81 and CDM-83) and elastic washers around the bolt which ensure that no acoustic bridges are created via the bolts (CDM-FIX). By installing this solution, the connection is completely disconnected and high impact sound insulation is achieved.
