- X4S:

Torch-applied, high performance, elastomeric bitumen, mica finished capping sheet, 4.2 mm-thick. Features a spunbond 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 only suitable for applications where it will be covered with hard landscaping such as pavers or promenade tiles.

• Width: 1 m.

• Length: 10 m.

• Thickness: 4.2 mm.

• Weight: 5 kg/m².

• Surface: Top: Mica; Bottom: Thermofusible polyethylene.

• Softening point: >100°C.

• Tensile strength: Length >800 N/50 mm; transverse >800 N/50 mm.

• Elongation at break: Length >35%; transverse >35%.

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 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:

• Bauder Bitumen Compact Vertical Outlet DN100: Insulated internal outlet, 6.1 L/s.

- 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.
