Isocheck ULTIMO - NOTE: this product is no longer available -

Acoustic floor system: for timber or concrete floors

The Isocheck ULTIMO system is designed to reduce sound transmission through traditional joisted timber floors, where access to ceilings may be limited.

Isocheck ULTIMO consists of 5 – 6mm Isofiba resilient layer bonded to 10mm fibre reinforced gypsum board, with a bonded top layer of 9mm thick t&g moisture-resitant board.

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, 2013 and 2015.
