Karmafloor Acoustic Batten is suitable for use in new build and refurbishment timber and concrete separating floors. The batten is used for even surfaces where only a simple acoustic solution is required. The battens are FFT1 and FFT3 compliant for Robust Details E-FC-1, 2, 7, E-FS-1 and E-FT-1, 2, 3.

Product description

Dressed softwood timber batten with a uniquely formulated and contoured
resilient foam layer adhered to the underside.


Manufactured from:
  • Osmose treated timber, currently the most environmentally friendly
    preservation available
  • 100% recyclable closed cell, non-crosslinked foam which meets the
    requirements of EN 12402-7:2006 clauses 4.8.2.3 and 4.8.2.4 for
    thermal stability and compressibility.

Product features

  • Three depths available – 52mm, 67mm and 77mm nominal. Depth
    measurements are based on full domestic loading having been
    applied. For uncompressed dimensions add 3mm
  • Owing to the high compressive strength of the foam the resilience
    strong, resulting in minimal deflection under load. As such only one
    type of batten is required removing the inconvenience of a separate
    high load-bearing product
  • The distinctive surface relief of the foam layer minimises contact
    between the lower surface of the batten and sub-floor, whilst the
    special chemical composition creates a material with excellent
    acoustic properties.
