Monarfloor Tri-Deck - Direct To Joist Acoustic Floating Floor System

Resilient overlay platform / floating floor direct to joist system.

Monarfloor Tri-Deck is designed to reduce sound transmission through timber floors where the existing timber floor will be removed but access to work on the ceiling below will be restricted.

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

Monarfloor Tri-Deck consists of a 5mm layer of foam rubber bonded to an 8mm layer of LRAC foam type I bonded which is then bonded to 22mm V313 P5 moisture resistant chipboard.
