2 To meet the Robust Details performance criteria, the mean of the test results must be at least 5dB better than the Building (Scotland) Regulations further information, please refer to our website, ,or for additional advice, phone the RDL Technical Helpline on 0870 240 8209To ensure the scheme continues to provide the expected high levels of performance, RDL conduct random visual inspections and tests on a proportion of sites registered.

4 The prescribedrobust Details contained herein are applicable tolimiting the transmission of noise only within newbuild domestic buildingswithin the scope of theBuilding (Scotland) Regulations Robust Details have undergone an extensivesound insulation testing regime, Robust designanalysis and independent audit and have satisfiedthe Robust Details Management Board that theyshould provide a level of sound insulation compliantwith Section 5. Only then can they be incorporatedwithin this Robust Details handbook . Importantly, the designer and the verifier can beconfident that when considering approval of abuilding warrant for new build housingincorporating Robust Details , compliance withMandatory Standard will be can be safely assumed that the pre-emptiveapproval of the building warrant is based on soundevidence and design noted previously, the Building (Scotland)Regulations 2004 recognise that compliance on sitecan only be achieved by having sufficient checks inplace to provide comfort to the designer and verifierthat the design proposals have been followed to theletter during the construction and installation phaseprior to completion and handover.

5 In essence,buildings containing designed elements ofconstruction to combat unacceptable levels ofnoise transmission, should be subjected to a post-completion assessment (and test) to confirm theirperformance test use of Robust Details provides an alternativeto pre-completion testing for demonstratingcompliance with the performance standards ofSection 5 for new build dwellings. Every dwellingbuilt using Robust Details needs to be registeredwith Robust Details Ltd and a plot registration fee paid. Each Robust detail includes materials andconstruction Details for the separating wall/floor andits key interfaces with other elements and should beread in conjunction with Appendix final page of each Robust detail is a checklist,which should be photocopied and used by the sitemanager/supervisor to confirm that the separatingwall/floor has been built correctly. The verifier mayask to see the is important that separating walls/floors and theirassociated junctions and flanking conditions areconstructed entirely in accordance with the relevantrobust detail ; otherwise the verifier may requirepre-completion testing to be carried tables on pages 4, 5 and 6 show which robustdetail separating floors and walls can be used :The guidance contained in this handbook relates only to Section 5.

6 The building work willalso have to comply with the requirements of all other relevant parts of the Building (Scotland)Regulations and other relevant testing is required on a wall or floor theuser should seek expert acoustic advice prior to construction information on the Robust Details scheme(including how to apply for new Robust Details ) isavailable on the Robust Details web site from: Robust Details LtdDavy AvenueKnowlhillMilton KeynesMK5 8 NBTelephone: 0870 240 8209 - Technical0870 240 8210 - GeneralFax: 0870 240 8203 Terms and Conditions:Please refer to for full terms and conditions. : UK registered trade mark no. 2291665 : trade mark Robust Details Limited 2011.
