T 08705 456123 F 08705 456356 E bgtechnical.enquiries@bpb.comInstallation overviewSocket detailing‘Plasterboard baffle’ - backing methodHoles in plasterboard linings for socket boxes should always beneatly cut and Gyproc Sealant should be applied where optimumacoustic performance and/or minimum air leakage is required. Infire-rated walls, the fire stopping design is dependant on theperiod of fire resistance required. The depth of ‘plasterboard baffle’should be approximately 150mm. Whilst the following exampledetails relate to 60 and 90 minute fire resistant specifications, theprinciple of the details can generally be adopted for 120 minutespecifications.In all instances, it is strongly recommended that the number ofpenetrations are minimised and back-to-back sockets should beavoided.Hilti CP617 Putty PadThe self-adhesive pad can be applied to either the rear of the backbox or as a liner to the inside.When applying to the rear, prior to installation, ensure the area ofapplication is free of excess dust, dirt, oil and water. Remove labelfrom one side of the pad and then apply to the rear of the box,ensuring an even overlap all the way round. Mould the overlapdown the sides of the box and then press firmly to thesurrounding plasterboard. Remove the remaining label.When fixing to the inside of a back box, ensure that the box hasbeen fully fitted with the socket screws in place. This is to ensurethat the fixing lugs that grip the plasterboard are not blocked bythe installation of the pad. Remove the label from one side of thepad. Line the box with the pad, neatly trimming any excessmaterial. Remove the remaining label.Where sockets are fitted in positive pressure areas such as firefighting shafts, it is recommended that the pads always be fittedto the inside of the box.In all installation cases, any insulation material that is in place mustnot be removed.Finally, ensure that as cables are drawn through, the pad ismoulded around them to ensure smoke tightness.Robust Details / PCTBoth the 'plasterboard baffle' backing method and the Hilti CP617Putty Pad method are recognised by Robust Details Ltd and can beused within the British Gypsum GypWall QUIET IWL system(E-WS-2 see figure 1) without the need for Pre-Completion Testing.The Hilti CP617 Putty Pad has been accepted by Robust Details Ltdas an alternative mechanism for sealing the rear of electricalservice penetrations in Robust Detail timber frame and metal frameseparating walls, as published in the Robust Details Part EHandbook.‘Sacrifial linings’The Robust Details pattern book also offers the alternative of a‘sacrificial’ lining in front of a separating wall to create a zone forservice installation. These service zones remove the need for servicepenetration of the actual Robust Detail separating wallconstruction, which in turn removes the risk of a loss in acousticperformance as a result of service penetrations.This method is increasingly migrating to projects where Pre-Completion Testing is being used, as best practice. However, it canlead to a downgrading of the D ntw + C tr performance of the basewall due to the introduction of additional cavities within the overallconstruction. Robust Detail walls are designed to exceed theApproved Document Part E requirement so the slight potentialdowngrade in performance caused by the ‘sacrificial’ lining wouldnot lead to system failure.Where Pre-Completion Testing is required however, depending onthe system specified, there may not be this level of ‘safety margin’,particularly at lower frequencies. Therefore, where additional‘sacrificial’ service installation zone linings have been specified innon Robust Details systems the most appropriate solution isdetailed below.British Gypsum recommend the following as a minimumspecification to ensure no reduction in the acoustic performance ofthe base partition: 70mm cavity with 25mm Isover APR 1200 anda single layer 15mm Gyproc SoundBloc board lining installed onone or both sides of the base partition construction.The Hilti CP617 Putty Pad can be used on metal back boxes inmuch the same way as with plastic ones. However, when fitting tothe rear of the metal box, the box should be unscrewed from thenogging, the pad applied and then the box re-fixed.For full installation details, refer to the British Gypsum SiteBook or visit www.british-gypsum.com5
