- Bauder lightning conductors:

Lightning conductor clips are a specially designed secure clip that allows for movement.

• Bauder Lightning conductor - Type 4: Polyvinyl chloride (PVC) coated or bare conductor.

- 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.
