Monarfloor Deck 18 – designed for domestic timber floors where the existing timber deck remains. Deck 18 consists of a layer of LRAC foam bonded to18mm V313 P5 moisture resistant chipboard.
Monarfloor 18 deck is a floating floor system that used in conjunction with a resilient bar ceiling creates a system that will attain regulation E level of soundproofing. The flooring system must be laid over an existing sub floor and not direct to joists. The installed system coupled with 100mm 45kg density mineral wool resilient bars and 2 layers of acoustic plaster board will give a system that should produce a 49 db airborne reduction coupled with 49 db impact sound reduction. Both these figures are generously within current regulation E building regulations.
An Alternative product which you might consider is the monarfloor deck 9 system that is specified in projects where the increase in floor level has to be kept to a minimum. Deck 9 consists of 8mm of LRAC foam bonded to 9mm thick moisture resistant M DF, giving an increase in floor level of only 17mm.
The simplest way of improving the airborne and impact sound performance of an existing timber floor is to overlay the floor with an isolating layer and a new wearing surface. Monarfloor offers three deck overlay systems for such applications:
Monarfloor Deck overlay systems may be used in new build or refurbishment projects, over 18mm chipboard, OSB board or a decking ply sub floor.
Installation of Monarfloor Deck system onto a timber subfloor
Monarfloor Deck overlay system on a timber sub-floor with a resilient bar ceiling
Monarfloor Deck overlay systems should be installed directly onto the sub-floor, in broken bond with all joints glued.
