Two-layer, self adhered, warm roof, bitumen membrane waterproofing system suitable for new build and refurbishment applications.
Suitable for new build and refurbishment applications and can be used in warm, cold and inverted roof scenarios, including green roof applications.
Bitumen warm roof system, incorporating torch-on bitumen capping sheet with self-adhered bitumen underlayer, insulation and self-adhered bitumen air and vapour control layer (AVCL).
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.
Features and benefits:
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 manufacturer for further information.

Product range |
Preparation | |
Horizontal work | Bauder Activator-Primer (Canister) APR01.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.
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. |
Skirtings and vertical work | As 'Horizontal work'. |
Air and vapour control layer | |
Type | KSD FBS.Guidance for specification option: Robust, self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with a mica finished upper surface to allow easy bonding of insulation using appropriate Bauder Insulation Adhesive. One side lap features an 80 mm wide glass fleece along the underside, and a 100 mm strip of aluminium foil above. The other side lap has a thermofusible film on the top surface. This arrangement ensures that laps are heat sealed using hot air or gas torch as appropriate to extrude a bitumen bead, thus ensuring waterproofing integrity.
DS1 DUO.Guidance for specification option: Self-adhesive elastomeric bitumen air and vapour control layer with patented “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. The product also features thermally activated bitumen stripes on its top surface to provide the bonding compound for the insulation boards. Allows for cleaner, safer and faster installation than traditional torch applied membranes.
