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 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. .

Monarfloor Deck overlay systems may be used in new build or refurbishment projects, over 18mm chipboard, OSB board or a decking ply sub floor.
