Bitumen cold roof system, incorporating torch-on bitumen capping sheet with self-adhered bitumen underlayer.
Bitumen cold roof system, incorporating torch-on bitumen capping sheet with self-adhered bitumen underlayer.
Bauderflex Roof System is suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios. Includes the option of using a root resistant cap sheet, making this waterproofing system suitable for green roof situations.
See BBA certification 10/4744. Bauderflex can meet current UK Building Regulations Part B for external fire protection and can feature torch-free and safe to torch installation on combustible details.

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.

Standard product features | Primer: Contact Bauder to confirm substrate suitability if required. - Activator-Primer (Canister) APR01 - Black: 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.
Underlayer: - BauderTEC Sprint DUO: A technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. The product features a glass fleece reinforcement for strength and stability. The product benefits from cleaner, safer and faster installation than traditional torch-applied membranes.

Product Options | Capping sheet: - K4E: Torch-applied, high performance, elastomeric bitumen, mineral finished, capping sheet, 4.2 mm-thick. 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. Expandable graphite fire retardant is also incorporated to reduce spread of flame and the product is available in a choice of three colours.
- X4S: Torch-applied, high performance, elastomeric bitumen, mica finished capping sheet, 4.2 mm-thick. Features a spunbond 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 only suitable for applications where it will be covered with hard landscaping such as pavers or promenade tiles.
Accessories: - Bauder GRP Trim: 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 Aluminium Termination Bar: 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: 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. - Bauder lightning conductors: Lightning conductor clips are a specially designed secure clip that allows for movement.
- Bauder insulated rainwater outlets: 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 Photovoltaic Mounting System: 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 LiquiFIBRE Detailing Kit: 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: 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. - Bauder rooflights/ glazing/ ventilation: All these glazing products are fully compatible with the roof waterproofing systems. Consult Bauder for details and insert requirements.
