Bauder Stripes System
When to specify...
When a roof covering is reaching the end of its serviceable life, but is essentially still waterproof, the BauderTHERM 'Stripes' system can overlay the existing system to extend the life expectancy of the roof providing that the thermal properties of the roof are satisfactory. Installation features torch-free and safe to torch installation on or near combustible details. This system is only suitable for refurbishment projects.
Key features
■□ 5.2mm thick, torch bonded elastomeric bitumen membrane.
■□ Utilises Torch-free detailing on or adjacent to combustible construction materials.
■□ Stable in extreme weather conditions tested to the following European Standards; cold bending test (EN 1109) and heat stability test (EN 1110).
■□ Guaranteed system.
The solution
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 overlaid with a recovery board. Refurbishment of roofs containing insulation are also suitable, providing they do not suffer from moisture contamination or degradation problems.
It is possible to overlay existing waterproofing where a small amount of entrapped moisture is present, as the stripes finish to the underside of the BauderSL500 cap sheet allows any vapour pressure to dissipate in a controlled fashion, reducing 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 and a longer life expectancy for the roof.
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 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.

Our torch-free detail design specifically delivers secure safe application techniques in the vicinity of combustible construction materials located on, or connected to, the roof such as timber substrates or upstands; abutments to cladding, roof tiles, slates or thatch; or even debris such as dry leaf material that is at risk from ignition. The application methods meet NFRC Guidance Document 'Safe2Torch'
