Skirtings and vertical work | As 'Horizontal work'. |
Waterproof covering | |
First layer | |
Type | BauderFLEX G4E.Guidance for specification option: A 4 mm, heavy-duty, torch-applied elastomeric bitumen underlayer with a strong woven glass reinforcement to provide an extremely high tensile strength.
|
Attachment | Torch applied. |
Top layer | |
Type | K5E.Guidance for specification option: Torch-applied, heavy-duty, elastomeric bitumen, mica-finished capping sheet, 5 mm thick. Features a spun-bound 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 is only suitable for applications where it will be covered with hard landscaping such as pavers or promenade tiles.
K5K, Brown.Guidance for specification option: Torch-applied, heavy-duty elastomeric bitumen; mineral-finished capping sheet, 5.2 mm thick. Features a spun-bound 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.
K5K, Charcoal Grey.Guidance for specification option: Torch-applied, heavy-duty elastomeric bitumen; mineral-finished capping sheet, 5.2 mm thick. Features a spun-bound 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.
K5K, Grey Slate.Guidance for specification option: Torch-applied, heavy-duty elastomeric bitumen; mineral-finished capping sheet, 5.2 mm thick. Features a spun-bound 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.
Manufacturer guidanceNot for use with green roof systems. |
Attachment | Torch applied. |
Detail work | |
Flashings | Not required.Bauder GRP Trim.Guidance for specification option: GRP roof edge trim for use with Bauder bituminous roof systems. Available in colours of either grey or black, and a choice of profiles to suit the requirements of most projects. 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 | Not required.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. |
Insulation | |
Type | Bauder JFRI PREMIUM+ Inverted Insulation.Guidance for specification option: Insert required thickness, 85–240 mm in 5 mm increments. Designed specifically for inverted roof applications.
Consult manufacturer's literature for further details. Bauder JFRI PREMIUM (300) Inverted Insulation.Guidance for specification option: Insert required thickness, 90–240 mm in 5 mm increments. Designed specifically for inverted roof applications.
Consult manufacturer's literature for further details. Bauder XPS (300) Inverted Flatboard.Guidance for specification option: Insert required thickness.
Bauder XPS (500) Inverted Flatboard.Guidance for specification option: Insert required thickness.

Attachment | Loose laid (and suitably ballasted).Guidance for specification option:
|
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 insulated rainwater outlets.Guidance for specification option: 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 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.
Hard landscaping/ Ballast options.Guidance for specification option: Consult manufacturer for information. |
Water Flow Reducing Layer/ Vapour Permeable Membrane | Bauder JFRI WFRL. Guidance for specification option: Flexible and breathable sheet of polypropylene strands randomly spun-bound together, supplied as part of the JFRI Inverted Insulation system to minimize water flow through and below the insulation, therefore improving thermal performance.
Bauder XPS WFRL. Guidance for specification option: Flexible and breathable geotextile membrane of polypropylene strands randomly spun-bound together, supplied as part of the Bauder XPS Inverted Insulation system to minimize water flow through and below the insulation, therefore improving thermal performance.
