ql10-floating floor resilent layer 10mm

Incorporating the latest changes to the Approved Document E, the minimum and maximum airborne noise and impact sound insulation requirement for separating floors are as follows: . Properties Values Airborne Sound Reduction DnTw,w+C;tr Impact Sound Level LnTw Conversion 43dB or greater 64dB or less New Build 45dB or greater 62dB or less To comply with the requirements of Document E, R10 sound insulated separating floors have been tested in accordance with BSEN ISO 717-1997 and BSEN ISO 717:1997. Substituting the 25mm mineral wool floating layer normally specified with a more stable and efficient recycled rubber resilient layer. 10mm thick sound absorbing Acousticel R10 is installed onto timber suspended floors as detailed above. Note: Existing or new square edged timber floors should be overlaid with our SBM5 before installing the R10 and the ceiling should be supported with our 16mm deep Resilient Bars. With a floating layer of 19mm thick QUIETBOARD cement impregnated t&g chipboard -placed on top of the R10 acoustic insulation as shown above, the following site test result was recorded: . Site test result Airborne DnT,w+Ctr 48dB Impact LnTw 52dB With R10 and QuietBoard installed on top of a base floor of QuietBoard, the following site test result was recorded: Airborne DnT,w+Ctr 55dB Impact LnTw 55dB WHICH MEETS THE NEW CHANGE OF USE, CONVERSION AND NEW BUILD REQUIREMENTS NOTE! Size and spacing of the timber joists will affect the overall sound insulating performance. If the joists differ from those on the floor that was tested, please contact us for further advice. NOTE: Failure to follow the Application Instructions to the letter may result in a failed test! TYPE R570 FACE MATERIALS Recycled rubber from truck and car tyre origins and various foams e.g. Neoprene, EPDM and polyurethane are used throughout. Type R570 is tyre and EPDM foam 50:50 mix. BINDER The particles are bound with flexible polyurethane, which is non-hazardous and odourless. This is chemically inert. TILES All tiles are sold in one metre by one metre square format. SUMMARY Ryburn tiles do not contain separate ingredients or materials which would be hazardous to health under the terms to the C.O.S.H.H regulations 1988. SPECIFICATIONS .
