Isocheck RENOVO acoustic flooring system from Isomass is designed to reduce impact sound transmission through traditional joisted timber floors where there is little or no access available to enhance the ceiling below for both sound insulation and additional fire protection. Isocheck RENOVO consists of 8mm environmentally friendly Ecopoli resilient layer bonded to 18mm p5 moisture resistant chipboard. When installed as part of a complete party floor construction either system enables a traditional timber joisted floor to meet the sound transmission standards of Approved Document E 2003 and subsequent amendments in 2004, 2010, 2013 and 2015. Isocheck RENOVO-s resilient layer (ecopoli) contains 20% renewable vegetable based components compared to traditionally manufactured petroleum-based foams which contain zero. On top of that there is the added benefit of using less fossil fuel components in its manufacture. A completely new catalyst enables castor oil to be employed in the production of low-emission polyols. With castor oil accounting for 30% of the polyol-s total weight it can contribute to yet another renewable recipe to help our environment. Performance Benefits (ideal for listed buildings) Isocheck RENOVO has been tested by the NHBC for use in conversion applications and comfortably meets the required performance standards as specified in Approved Document E 2003 without a proprietary resilient bar or MF suspended ceiling system. So now (in cases where the floor void is 200mm or above) it is not necessary to remove a direct fixed ceiling and the existing floor may be rebuilt as a working platform before Isocheck RENOVO is incorporated over the floorboards or chipboard. Making the Isocheck RENOVO system one of the last operations thus avoiding costly protection necessary on alternative direct to joist systems. Castor seed is the source of castor oil, which has a wide variety of uses. The seeds contain between 20% and 90% oil that is rich in triglycerides, mainly ricinolein. Native to Africa, Asia and now naturalised throughout Australia, it is often abundant along watercourses and floodplains. .
