Monarfloor Acoustic Tri-Batten System

Monarfloor Tri-Batten System consists of a 15 mm layer of LRAC foam Type III bonded to a timber batten with a 3 mm-thick geotextile fibrous insulation mat, improving impact sound performance and enabling easy and secure fixing to the sub-floor.

Features and benefits:

  • Designed to support floor loadings defined in BS 6399-1: 1996.
  • The system incorporates recycled Low Resonance Acoustic Chip foam, providing excellent impact improvement characteristics and superior stability.
  • All LRAC foam used in Monarfloor systems is flame retardant.
  • The Acoustic Tri-Batten System is designed to reduce sound transmission through timber frame floors in a timber framed structure and can be overlaid directly with an 18 or 22 mm chipboard deck.
  • When installed as part of a complete sound reduction system, Tri-Battens enable a timber floor to meet the sound transmission regulations of Part E.


  • DnT,w (Part H): 57 dB.
  • DnT,w + Ctr: 48 dB.
  • L,nt,W: 54 dB.
