Isocheck PRIMO 26, 30 & PRIMO HL

Acoustic flooring systems: for use in new build and older timber and steel frame construction

Isocheck PRIMO acoustic flooring systems are designed to reduce sound transmission through traditional / composite timber / steel joisted floors within new build and older light weight frame constructions.

Isocheck PRIMO 26 consists of a 8mm layer of melamine-free APF bonded to 18mm P5 V313 moisture resistant chipboard. Isocheck PRIMO 30 consists of a 8mm layer of APF bonded to 22mm P5 V313 moisture resistant chipboard.

When installed as part of a complete party floor construction the system enables a timber floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015.
