Flame-Free/ Safe to Torch Zone Detailing:
Bauder was the first manufacturer to pledge its support to the Safe2Torch initiative, introduced by the National Federation of Roof Contractors (NRFC) in July 2017. The flame-free detailing designs specifically deliver secure and safe installations 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 debris such as dry leaf material that is at risk from ignition.
Flame-free detailing can be integrated into all bituminous waterproofing solutions to give versatile, safe installation techniques for all roof types, site conditions and budgets.
The waterproofing flashing should be turned up by at least 150 mm around features such as rooflights, parapets and service pipes passing through the roof, detail work to upstands, edge details, flashings, etc. The membrane should not be taken up in one piece. Consult manufacturer for further information.

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.
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.
Manufacturer guidanceContact manufacturer to confirm substrate suitability, if required. |
Skirtings and vertical work | As 'Horizontal work'. |
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.
Manufacturer guidanceTo be fully specified separately. |
Attachment | Self-adhered. |
Top layer | |
Type | Bauder PYE PV 200 S4.Guidance for specification option: Torch-applied, elastomeric bitumen, mica-finished capping sheet, 4.2 mm thick. Features a spun-bound polyester reinforcement to allow the finished product to cope with structural movement without fracture. Its mica finish means that it has no integrated UV protection, therefore is only suitable for applications where it will be covered with hard landscaping, such as pavers or promenade tiles.
BauderFLEX K4E, Brown.Guidance for specification option: Elastomer bitumen torch-on capping sheet. The product features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation. Product has been fire tested as part of a system assembly and this information can be obtained in the Fire Test Report available from Bauder Ltd.
BauderFLEX K4E, Charcoal Grey.Guidance for specification option: Elastomer bitumen torch-on capping sheet. The product features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation. Product has been fire tested as part of a system assembly and this information can be obtained in the Fire Test Report available from Bauder Ltd.
BauderFLEX K4E, Grey Slate.Guidance for specification option: Elastomer bitumen torch-on capping sheet. The product features a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation. Product has been fire tested as part of a system assembly and this information can be obtained in the Fire Test Report available from Bauder Ltd.

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 | Not required.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. |
Welted drips | Required.Guidance for specification option: Insert requirements. Not required. |

System accessories | Not required.Bauder lighting conductors.Guidance for specification option: Lightning conductor clips are a specially designed secure clip that allows for movement.
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:
BauderSOLAR F XL Photovoltaic Mounting System.Guidance for specification option: Bauder flat roof PV mounting solution for framed solar modules. The mounting units are secured to the roof using a membrane-to-membrane welding technique. This installation method means that the roof is not compromised by penetrations for fixings, nor is it ballasted, which would add additional weight loading to the roof. Specifically designed to be installed on Bauder bituminous or single-ply waterproofing systems and provide a lightweight, low-risk and quick-to-install mounting solution for framed solar modules. Bauder rooflights/ glazing/ ventilation.Guidance for specification option: All these glazing products are fully compatible with the roof waterproofing systems. Consult manufacturer for details and insert requirements.
