Achieving good levels of Sound Insulation to ensure you pass your sound test and achieve Part E compliance can seem a daunting task. We have put together a myriad of commonly used soundproofing wall and soundproofing floor solutions, with the simple aim of achieving passing your Part E sound test.

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.
