Torch-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 torch-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.
Torch-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 Bauder for further information.
Features and benefits of Torch-Free/ Safe to Torch Zone Detailing:
Color | Grey Guidance for specification option: Mineral finish is Charcoal Grey. |

CAWS | J41/130 Built-up reinforced bitumen membrane cold deck roof covering J41/12 Reinforced bitumen membrane cold deck roof covering |
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. Bauder SA Bonding Primer is a synthetic rubber-based primer applied by a roller or brush. 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 KSA DUO 35.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.
|
Attachment | Self-adhered. |
Top layer | |
Type | BauderKARAT.Guidance for specification option: Polymer bitumen dual formulation torch-on capping sheet. APP plastomeric top and SBS elastomeric bottom. The product features a 300g/m² spunbond polyester/ glass composite reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation.
Manufacturer guidanceNot for use with green roof systems. |
Attachment | Torch applied. |
Detail work | |
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, isocyanate 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, isocyanate and halogen free. |
Welted drips | Required.Guidance for specification option: Insert requirements. Not required. |
Cover strips | Required.Guidance for specification option: Insert requirements. Not required. |
Ancillary items | Required.Guidance for specification option: Insert requirements. Not required. |
Surface protection | Not required.Required.Guidance for specification option: BauderGREEN FSM 600 protection mat laid on the completed waterproofing to protect the completed waterproofing from mechanical damage. Must be used with decorative ballast finishes. |
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 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 high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet. Designed for use when connecting to conventional drainage systems, with excellent flow rate performance 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.
