Monarfloor Fastfloor Acoustic Cassette Flooring Systems - Intermediate Floors (Houses)

Monarfloor IWS Fastfloor Cassette Flooring Systems - Intermediate Floors (Houses)

The intermediate floor is a simple to use, fully accredited acoustic floor system that delivers real benefits. A unique top hung detail with reinforcing plate providing accredited performance.

Independently tested market leading acoustics – up to 4 dB better than current requirements. A typical intermediate floor can achieve a sound reduction of 43dB with 220mm IWS-Joists with 12.5mm ceiling at 600mm joist centres.

With ancillary products such as ply gusset plates, backer, filler and squash blocks not required. Mid-span blocking/strutting can be omitted, a reduction in the range and number of connectors, and the effective, short (during construction) and long-term fire protection, gives a real robust floor system to the market.
