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.
