The isocheck 37T system is designed to replace floorboards and reduce sound transmission whilst thermally enhancing traditional joisted timber floors.

Isocheck 37T consists of 10mm reconstituted ACF (acoustic chip foam) and the added isolation of a 5mm Isofiba layer, bonded to 22mm P5 V313 moisture resistant chipboard.

When installed as part of a complete party floor, this system enables a traditional timber joisted floor to meet the sound insulation standards of ADE 2003 (amended 2004).

Applications

To be used directly on timber joists for conversions or when using a direct fix ceiling.
