Monarfloor Acoustic Tri-Batten System

Monarfloor Acoustic Tri-Batten floating floor systemRDL FFT1 Resilient composite deep batten system.
FFT3 Resilient composite standard batten system

The Monarfloor Acoustic Tri-Batten floating floor system is designed to reduce sound transmission through timber frame floors in a timber framed structure and can be overlaid directly with an 18mm or 22mm chipboard deck. The system consists of a 15mm layer of LRAC foam type III bonded to a timber batten with a 3mm thick geotextile fibrous isolation mat that improves impact sound performance and enables easy and secure fixing to the sub-floor.

Monarfloor Tri-Batten's should be positioned on the timber sub-floor and stapled in place through the geotextile mat. It should then be overlaid with plasterboard plank and chipboard flooring laid in a broken bond pattern.  For specific detailing please refer to our Technical Department.

When installed as part of a complete sound reduction system it enables a timber floor to meet the sound transmission regulations of Part E.
