Total bitumen green inverted roof system, incorporating inverted insulation, torch-on bitumen root resistant capping sheet with self-adhered bitumen underlayer.
Total bitumen green inverted roof system, incorporating torch-on bitumen root resistant capping sheet with self-adhered bitumen underlayer, insulation and self-adhered bitumen vapour barrier.
Bauder Total Green Roof System (BTGRS) 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.
Bauder Inverted Roof systems should be ballasted/ landscaped to prevent wind uplift and/ or floatation. Type, thickness, weight of landscaping should be agreed with Bauder per bespoke project basis.
See BBA certification 10/4744. BTGRS can meet current UK Building Regulations Part B for external fire protection.

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 KSA 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 lattice reinforcement for strength and stability.The product benefits from cleaner, safer and faster installation than traditional torch-applied membranes.
Capping sheet: - Plant E: A high quality, heavy duty, torch-applied, elastomeric bitumen capping sheet. The product features chemically treated bitumen to deliver superior root resistance which has been tested and approved by the FLL. The membrane is reinforced with 250 g/m² spunbond polyester fleece to allow the finished product to cope with structural movement without fracture. Expandable graphite fire retardant is also incorporated to reduce spread of flame.

Bauder XPS GG (500) Inverted Insulation Flatboard: A range of flat high performance rigid extruded polystyrene insulation boards.
Bauder XPS GG (700) Inverted Insulation Flatboard: A range of flat high performance rigid extruded polystyrene insulation boards.
Water flow reducing layer (Vapour permeable membrane): - Bauder JFRI WFRL: Supplied as part of the JFRI Inverted Insulation system to minimize water flow through and below the insulation.
- Bauder XPS WFRL: Supplied as part of the XPS GG Inverted Insulation system to minimize water flow through and below the insulation.
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:
- 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.
- Hard landscaping/ Ballast options: Consult Bauder for information. |
