The Isocheck Shallow Batten system is designed to reduce sound transmission through a concrete structural sub-floor.

Isocheck Shallow Batten consists of a layer of 8mm Isopoli bonded to a FSC-certified softwood batten. Should the requirement be for a batten height other than that specified on this page please contact us for further technical advice and suitability.

When installed as part of a complete party floor construction it enables a concrete floor to meet the sound transmission standards of ADE 2003 and subsequent amendments in 2004, 2010 and 2013.


To be used over concrete floors for conversions, refurbishments or new build (to hide services or accommodate underfloor heating beneath the floor) with a new ceiling as illustrated.

Performance (on the two New Build Robust Detail constructions illustrated)

Treated floor meets with the New Build Robust Detail descriptive FFT3, typically within Robust Details EFC-1, EFC-2, EFC-7 and EFS-1. Two typical alternative constructions are shown above.

Compliance with Code for Sustainable Homes is possible; please contact Isomass for design advice.
