Single ply Thermofol polyvinyl chloride (PVC) cold roof system incorporating Thermofol single ply membrane for mechanical fixing.
Single ply Thermofol polyvinyl chloride (PVC) cold roof system incorporating Thermofol single ply membrane for mechanical fixing.
Bauder Single Ply Thermofol PVC 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. Can also be used for extensive green roof situations.
See BBA certification 06/4354. Thermofol can meet current UK Building Regulations Part B for external fire protection.
Key features:
Benefits:
Please note that profile metal decks will require a plywood/ Oriented strand board (OSB) overlay for cold roofs.

Product Reference | Bauder Single Ply Thermofol Cold Roof Membrane System Mechanically Fixed |
Waterproof membrane | Thermofol U1.2 mm, 1.5 mm, 1.8 mm, or 2 mm polyester reinforced, for all applications except for fixing over existing bitumen. Thermofol U15 FB1.5 mm, fleece backed polyester reinforced, for all applications. |
Separation layer | GV120 FleeceLightweight glass isolation fleece loose laid to provide isolation between plywood decks, other rough surfaces, over existing bituminous surfaces and Thermofol U (unbacked – PVC membrane). Only required where non-fleece backed membranes (U12/U15/U18/U20) are used. |
Attachment | Membrane fastenersBauder only approves the use of fasteners from manufacturer/supplier companies with associate membership to SPRA. Fasteners are included within the Bauder guarantee when supplied from SFS Group Fastening Technology Ltd when the project is covered by a Bauder Ltd Product and Workmanship guarantee. |
Accessories | See 'Options’ below and insert requirements. |
Standard product features | Separation layer: - GV120 Fleece: Lightweight glass isolation fleece loose laid to provide isolation between plywood decks, other rough surfaces, over existing bituminous surfaces and Thermofol U (unbacked – PVC membrane). Helps to prevent damage and punctures to Thermofol U membrane and to prevent plasticiser migration from bitumen surfaces.

Product Options | Detailing: The waterproofing 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. should be carried out using either Thermofol D membrane adhered directly to the substrate using Bauder Thermofol Contact Adhesive or mechanically fastened using Thermofol U membrane. Detailing should be carried out with a separate flashing. Consult Bauder for further information on detailing. Waterproof membrane: - Thermofol U15 FB Membrane: A fleece backed, polyester reinforced Polyvinyl Chloride (PVC) membrane, designed for both adhesive and mechanical fastening. Both mechanically fastened and adhered systems are usually installed using hot air welding techniques at the seams, where the sheets are fused together by heat, creating a totally secure homogenous layer.
- Thermofol U12, U15, U18, U20 Membrane: A polyester reinforced Polyvinyl Chloride (PVC) membrane, providing a strong, versatile solution for both adhesive and mechanically fastened roofing projects. The surface resists UV damage and is highly solar reflective in Light Grey colour. It has a high tensile strength and is reinforced with a pre-coated polyester cross-weave to make it resistant to tears and punctures, ensuring durability. There is a wide range of fasteners available for mechanical attachment of the membrane to metal, timber, concrete and many other decking materials.

- Bauder Thermofol Rigid PVC rainwater outlets:
Bauder outlets are sized to indicate the actual internal diameter of the spigot. For information on non-standard sizes and refurbishment applications, please contact Bauder Technical Department.
- Bauder Leaf Guard – Long Leg for Rigid PVC Vertical Outlets:
This Bauder Leaf Guard is designed to fit into Bauder Rigid PVC rainwater outlets. For information on non-standard sizes and refurbishment applications, please contact Bauder Technical Department. - Bauder Thermofol Stainless Steel rainwater outlets: A high performance stainless steel outlet with factory installed Thermofol membrane flange. Supplied with an O-ring and a wire ball leaf grill.
Bauder outlets are sized to indicate the actual internal diameter of the spigot. For information on non-standard sizes and refurbishment applications, please contact Bauder Technical Department.
- Bauder Thermofol Rigid PVC Parapet Outlet - DN 100 mm: A rigid PVC parapet rainwater outlet enabling Thermofol membrane to be welded to the flange plate. UV stable throughout. The unbacked Thermofol membrane should be heat welded up to the aperture to ensure colour consistency on the roof.
Bauder outlets are sized to indicate the actual internal diameter of the spigot. For information on non-standard sizes and refurbishment applications, please contact Bauder Technical Department. - Bauder Thermofol Emergency Overflow Outlet: An extruded PVC emergency overflow outlet compatible with Thermofol membrane.
For information on non-standard sizes and refurbishment applications, please contact Bauder Technical Department. - Bauder Thermofol Embossed Walkway Membrane: Bauder Thermofol Embossed Walkway is a 2 mm thick, reinforced PVC membrane with dark grey embossed finish to be loose laid over the finished membrane surface. The membrane should be heat welded around its full perimeter to the surface of the finished waterproofing. - 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. For adhered and mechanically fastened Thermofol systems, (only suitable for use with U15 FB, U18 and U20). - 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.
