Name: Bauderflex Green Reinforced Bitumen Membrane Cold Roof System - Self Adhered (with Torch-On Capping Sheet).
Brand: Bauder Ltd
SKU: wjUFRfY8MroXdcN958Zoq7

Preparation	-
Horizontal work	Activator-Primer (Canister) APR01 - Black. Guidance for specification option: Synthetic rubber resin-based primer, developed to provide the necessary preparation of substrates prior to the installation of self-adhesive and torch-applied membranes. The spray application offers improved film thickness speed of application (by up to 50% over roller applied products) and quick drying in a matter of minutes. Coverage: Approximately 96 g/m² (300 mm-wide spray one coat, 192 g/m² two coats). Two coats may be required for very porous substrates. Application temperature: +5 to +30°C. Drying time (at 10°C): 5–10 minutes. Colour: Black. Recoat time if left exposed: Four hours. Suitable substrates: Oriented strand board (OSB); plywood; timber; concrete; lightweight concrete or cementitious materials; metal; Bauder self-adhesive underlayers; existing asphalt and bitumen membranes; polyisocyanurate (PIR) insulation. Non-suitable substrates: Mica finished surfaces (e.g. KSD FBS); Laminated paper-foil faced insulation; expanded polystyrene (EPS) or extruded polystyrene (XPS) insulations; BauderROCK or mineral wool insulation; BauderGLAS or cellular glass insulation; copper; thermoplastic waterproofing membranes. SA Bonding Primer. Guidance for specification option: For Self-Adhesive membranes to Concrete and Screeded Substrates. Synthetic rubber-based primer, specially formulated to increase the bond strength of Bauder self-adhesive bitumen membranes to a wide range of substrates, including timber, concrete, brick, metal and most plastics. Coverage: approximately 200–300 g/m² (depending on substrate porosity). Application temperature: +5 to +30°C. Drying time: approximately 30 minutes, dependent upon ambient temperature and material porosity. Colour: Black. Recoat time if left exposed: Four hours. Suitable substrates: timber, concrete, brick, metal and most plastics. Manufacturer guidance Contact manufacturer to confirm substrate suitability if required.

Waterproof covering	-
First layer	-
Type	BauderTEC Sprint DUO. Guidance for specification option: Elastomer bitumen self-adhesive underlayer with variable technology for lap sealing. The two side laps of the membrane have differing finishes. On one lap there is a self-adhesive finish, whist the opposite lap has a glass fleece. This allows the membrane to be sealed with either a gas torch or hot air welder. Width: 1 m. Length: 15 m. Thickness: 2 mm. Weight: 2.5 kg/m². Surface, top: foil; bottom: peel-off release film covering self-adhesive bitumen. Reinforcement: 200 g/m² glass lattice. Cold bending test: -30°C. Softening point: >100°C. Tensile strength: length >1000 N/50mm; transverse >1000 N/50mm. Elongation at break: length >2%; transverse >2%. Manufacturer guidance To be fully specified separately.
Attachment	Self-adhered.
Top layer	-
Type	BauderPLANT E 42. Guidance for specification option: Elastomer-bitumen torch on capping sheet with root-resistance according to FLL. The product features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture. Width: 1 m. Length: 7.5 m. Thickness: 4.2 mm. Weight: 5 kg/m². Surface, top: green slate mineral chippings; bottom: thermofusible polyethylene. Reinforcement: 250 g/m² polyester fleece. Cold bending test: -36°C. Softening point: >120°C. Tensile strength: length >1000 N/50 mm; transverse >1000 N/50mm. Elongation at break: length >45%; transverse >45%.
Attachment	Torch applied.

Flashings	Bauder GRP Trim. Guidance for specification option: GRP roof edge trim for use with Bauder bituminous roof systems. Available colours of either grey or black and a choice of profiles to suit the requirements of most projects. Bauder GRP Water Check Trim. Guidance for specification option: GRP water check trim to be used on parapets and perimeter kerbs wider than 200 mm – must not be used on its own as a check kerb. Available in black only. Bauder Aluminium Termination Bar. Guidance for specification option: Natural finish aluminium alternative to a lead counterflashing for use at upstand details to give protection to the top edge of the waterproofing. It should be restricted to use on upstands where a chase cannot be cut into the wall. Bauder GRP Termination Bar. Guidance for specification option: Black glass-reinforced plastic (GRP) alternative to a lead counterflashing for use at upstand details to give protection to the top edge of the waterproofing. It should be restricted to use on upstands where a chase cannot be cut into the wall.
Skirtings and upstands	Bauder LiquiFIBRE Detailing Kit. Guidance for specification option: Fast-curing waterproofing resin containing fibre reinforcement that can be used for detailing awkward shapes or inaccessible areas where using LiquiDETAIL is impractical. PMMA-based resin that requires a catalyst and is solvent-free, isocyanate-free and halogen-free. Bauder LiquiDETAIL. Guidance for specification option: Cold liquid-applied fast-curing waterproofing resin that can be used on upstands and details. PMMA-based resin that requires the addition of catalyst to trigger curing and is solvent-free, isocyanate-free and halogen-free. Not required.

Ancillary items	Required. Guidance for specification option: Insert requirements. Not required.
Surface protection	Not required.
System accessories	Not required. Bauder lightning conductors. Guidance for specification option: Lightning conductor clips are a specially designed secure clip that allows for movement. Bauder Lightning conductor clips – Type 4: polyvinyl chloride (PVC)-coated or bare conductor. Bauder rainwater outlets. Guidance for specification option: Bauder has a range of insulated or stainless-steel rainwater outlets. The insulated outlets can be used for maintaining thermal continuity at drainage points. Suitable for warm, cold and inverted roof construction. The BRE Certified (report no. HPR357-303748) high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet body. Designed for use when connecting to conventional drainage systems and is suitable for both new build and refurbishment projects. Outlets are included in the Bauder waterproofing system guarantee as they are integrated components. Flow rate figures (where applicable) are based on BS EN 12056:3:2000, typically taken using a 35 mm header of water including leaf grille: Bauder Bitumen Compact Vertical Outlet DN100: Insulated internal outlet, 6.1 L/s. Bauder Bitumen Vertical Outlet DN70: Insulated internal outlet, 7.1 L/s. Bauder Bitumen Vertical Outlet DN150: Insulated internal outlet, 7.2 L/s. Bauder Bitumen Letterbox Parapet Outlet DN 205 including stainless-steel leaf guard, 2.02 L/s. Bauder Bitumen Parapet Outlet DN 100 including stainless-steel leaf guard, 1.06 L/s. Bauder Bitumen Vertical Refurb Outlet DN70, designed to ensure the maximum flow rate of the existing downpipe is not exceeded. Bauder Bitumen Vertical Refurb Outlet DN95, designed to ensure the maximum flow rate of the existing downpipe is not exceeded. Bauder Bitumen Vertical Refurb Outlet DN145, designed to ensure the maximum flow rate of the existing downpipe is not exceeded. Bauder Bitumen Parapet ‘Tell-Tale’ Overflow DN50, designed to be used in conjunction with other roof drainage outlets to ensure that there is no water ingress into the build and that the structural load of the roof is not exceeded and provides a visible warning that the roof is holding excessive water.
