Monodeck 20T system is designed to reduce transmission through timber floors in situations where finished floor height is critical.
Monodeck 20T boards consist of a layer of 8mm reconstituted ACF (Acoustic Chip Foam) bonded to 12mm p5 moisture resistant chipboard.
When installed as part of a complete sound reduction system, it enables a timber floor to meet the sound transmission regulations of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 & 2015.
