GENERAL DETAILINGbauder.ie64INSULATED UPSTANDThe pre-formed metal flashing plays an important part in the integrity of the roof and should be pointed with Bauder mastic sealant. Pre-formed metal angles are mechanically fixed where the angles change by 90° and the flexible detailing membrane welded securely.It is important that any cavity tray that exists is situated above the metal flashing to avoid water ingress behind the Bauder single ply waterproofing system.All upstands should be a minimum 150 mm high in order to conform to Codes of Practice BS 8217:2005.The vertical section of insulation needs to be provided to prevent cold bridging through the inner skin of brickwork whenever an insulated wall is present.ENCAPSULATED PARAPETThe best way to ensure total waterproofing integrity at a parapet detail is to dress the Bauder single ply membrane all the way up and over the wall, taking it under the copping or capping, providing a cavity bridge is provided as a solid base. Pre-formed metal angles are utilised where the angles change by 90° and the flexible detailing membrane welded securely.VERTICAL CLADDINGIt is important that any waterproofing used behind the cladding system is positioned in front of the Bauder products to ensure water is nor directed behind the upstand flashing. Pre-formed metal angles are mechanically fixed where the angles change by 90° and the flexible detailing membrane welded securely.

In a warm roof situation a timber edge kerb must be incorporated to provide a solid edge for mechanical fixing of the membranes and pre-formed metal.INTERNAL OUTLETKey to a successful installation is a full range of compatible accessories. One of the most important of these is the rainwater outlets. With all of the surface water being directed to the outlets by the use of falls in either the deck or insulation the joint of the waterproofing membranes to the outlet itself is a critical area. Bauder outlets are manufactured with a compatible membrane flange to ensure a watertight joint at this point. Each Bauder FPO and PVC system has its own range of compatible outlets to suit either vertical or horizontal drainage. Our range of standard outlets is designed to fit directly into the preformed socket of UPVC drainage down pipes.SEPARATION KERBWhenever the Bauder single ply system is to abut an adjacent existing waterproofing system it is advisable to incorporate a separation kerb. This has two purposes. Firstly it forms a defined edge to the roof, and secondly it ensures that any incompatibility of dissimilar products is avoided as they do not need to come into direct contact with each other. However, consideration must be given to avoid interruption of any drainage falls that may currently exist. Pre-formed metal flashings should be used in the same way as all other perimeter details.CADSpecification SupportCAD DRAWINGSwww.bauder.co.uk/technical-centreNBS SPECIFICATIONSwww.bauder.co.uk/technical-centreTECHNICAL HELPLINET: +44 (0)1473 257671E: technical@bauder.co.ukPROJECTS PORTFOLIOE: marketing@bauder.co.ukW: www.bauder.co.uk/media-centreTECHNICALGUIDE
