The Isocheck 32T system is designed to reduce sound transmission and thermally enhance traditional joisted timber floors.

Isocheck 32T consists of 6mm reconstituted ACF (Acoustic chip foam) and 4mm Isofiba, bonded to 22mm P5 V313 moisture resistant chipboard.

When installed as part of a complete sound reduction system, it enables a timber floor to meet the sound transmission regulations of Approved Document E 2003 and subsequent amendments in 2004, 2010 and 2013.

Applications

To be used over new or existing joists for new build, refurbishments or conversions with a new resilient bar ceiling.
