bauder.ie30BAUDERTHERM 'STRIPES'BAUDERTHERM 'STRIPES'When a roof covering is reaching the end of its serviceable life, but is still essentially waterproof, overlaying the existing system is a sensible way of considerably enhancing the life expectancy of the roof by at least 15 years; providing that the thermal properties of the roof comply with current Part L of the UK Building Regulations (Part J in Scotland). BauderTHERM 'Stripes' can be used over existing asphalt or reinforced bitumen membrane systems; roofs with a traditional chipping finish may also be suitable if the existing finish can either be adequately removed by a suitable mechanical scarifying machine, or overlayed with a recovery board. Refurbisment of roofs containing insulation are also suitable, so long as these do not already suffer from moisture contamination or degradation problems. It is possible though to overlay existing waterproofing where some entrapped moisture is present as the special stripes finish to the underside of our waterproofing layer allows any vapour pressure to dissipate in a controlled fashion and reduces the possibility of surface blistering after installation. BauderTHERM Stripes consists of a single layer membrane with two layers provided at all upstands and details to provide extra reinforcement at these more vulnerable areas. Utilising the X4E capsheet and X4U underlayer ensures robustness and a longer life expectancy for the roof.KEY FEATURESn 5.2 mm thick, torch bonded elastomeric bitumen membrane n 250g/m² spunbond polyester reinforcement to give a tensile strength of 1000N/50 mm. n Life expectancy in excess of 15 years. n Stable in extreme weather conditions for temperatures ranging from -30°C to +105°C when tested to the following European Standards; Cold bending test (EN 1109) and heat stability test (EN 1110).n Guaranteed for 12 years.The underside of the Bauder SL500 membrane features a highly adhesive thermally activated SBS elastomeric bitumen resin, set in a 'stripes' bonding pattern at pre-determined intervals across the membrane surface.This unique bonding pattern ensures an accurate 50% bond to the existing waterproofing beneath. The area between the stripes is coated with a special mica quartz finish that remains unbonded, allowing room for any future expansion of moisture vapour that may be present in the overlaid system. This technology helps to reduce the likelihood of interlayer blistering after installation, which is commonly associated with traditional overlays.Technical Guide Pages 33-41CADSpecification 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-centre
