• Acoustic floor to be used over existing floorboards for conversions, refurbishments, listed buildings requiring minimal structural change or new build with a decoupled ceiling.
• Isocheck 15T has also been tested for use over water-fed underfloor heating systems.

Isocheck 28T, 24T, 18T and 15T acoustic floor, is a high performance acoustic secondary floating floor systems designed to reduce impact sound transmission through traditional timber floors where no additional precautions are required for higher domestic loads in bathrooms and kitchens.

Isocheck 28T, 24T and 18T consist of a 6 mm layer of Isofiba bonded to 22 mm, 18 mm or 12 mm P5 V313 moisture resistant chipboard, whereas Isocheck 15T consists of a 5.5 mm layer of Isofiba bonded to 9 mm moisture resistant medium density fibreboard.

When installed as part of an Isomass approved separating floor construction either system enables a traditional timber joisted floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.
