Description

Total bitumen green cold roof system, incorporating torch-on bitumen root resistant capping sheet with self-adhered bitumen underlayer.

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.

See BBA certification 10/4744. BTGRS can meet current UK Building Regulations Part B for external fire protection.

Key features:

  • Capping sheet with tensile strength up to 1000 N/50 mm.
  • Withstands climatic extremes of over 100⁰C variation.
  • Patented self-adhesive DUO products. The "DUO" lap technology ensures thorough sealing of lap joints, even in lower temperatures.
  • Expandable graphite fire retardant reduces spread of flame.

Benefits:

  • Heavy duty, robust and extremely tough.
  • Service life in excess of 35 years as stated in BBA certificate 10/4744.
  • Resistant to European climatic conditions.
  • Membrane resists impact and tearing.

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.

  • Coverage: Approx. 96 g/m² (300 mm-wide spray one coat, 192 g/m² two coats). Two coats may be required for very porous substrates.
  • Application temperature: +5 to +30°C.
  • Drying time (at 10°C): 5-10 minutes.
  • Colour: Black.
  • Recoat time if left exposed: Four hours.
  • Suitable substrates: Oriented strand board (OSB); plywood; timber; concrete; lightweight concrete or cementitious materials; metal; Bauder self-adhesive underlayers; existing asphalt and bitumen membranes; polyisocyanurate (PIR) insulation.
  • Non-suitable substrates: Mica finished surfaces (e.g. KSD Mica); Laminated paper-foil faced insulation; expanded polystyrene (EPS) or extruded polystyrene (XPS) insulations; BauderROCK or mineral wool insulation; BauderGLAS or cellular glass insulation; copper; thermoplastic waterproofing membranes.

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.

  • Width: 1 m.
  • Length: 7.5 m.
  • Thickness: 3 mm.
  • Weight: 3.5 kg/m².
  • Surface: Top: Foil; Bottom: Peel off release film covering self-adhesive bitumen.
  • Reinforcement: 200 g/m² glass lattice.
  • Cold bending test: Top -25°C; Bottom -30°C.
  • Softening point: >100°C.
  • Tensile strength: Length >1000 N/50 mm; transverse >1000 N/50 mm.
  • Elongation at break: Length >2%; transverse >2%.

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.

  • Width: 1 m.
  • Length: 5 m.
  • Thickness: 5.2 mm.
  • Weight: 6 kg/m².
  • Surface: Top: Green slate mineral chippings; Bottom: Thermofusible polyethylene.
  • Reinforcement: 250 g/m² recycled spunbond polyester.
  • Cold bending test: -36°C.
  • Softening point: >120°C.
  • Tensile strength: Length >1000 N/50 mm; transverse >1000 N/50 mm.
  • Elongation at break: Length >45%; transverse >45%.

Product Options

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.
  • Bauder Bitumen Vertical Outlet DN70: Insulated internal outlet, 7.1 L/s.
  • Bauder Bitumen Vertical Outlet DN150: Insulated internal outlet, 7.2 L/s.
  • Bauder Bitumen Warm Roof Refurb Outlet DN63: Insulated internal outlet, 6.1 L/s.
  • Bauder Bitumen Warm Roof Refurb Outlet DN90: Insulated internal outlet, 5.7 L/s.
  • Bauder Bitumen Refurb Outlet DN95 – Un-insulated straight drop outlet, designed to ensure the maximum flow rate of the existing downpipe is not exceeded.
  • Bauder Bitumen Refurb Outlet DN125 – Un-insulated straight drop outlet, designed to ensure the maximum flow rate of the existing downpipe is not exceeded.
  • Bauder Insulated Parapet Outlet DN100 including pre-assembled pipe and dome grate: 0.6 L/s connected to external pipework; 0.7 L/s connected to external hopper.
  • Bauder Bitumen Blue Roof Vertical Outlet DN70: Insulated internal outlet. To be used in conjunction with Bauder Bitumen Blue Roof Flow Restrictor only. Bauder Bitumen Blue Roof Vertical Outlet DN70 (when used with Bauder Bitumen Blue Roof Flow Restrictor) flow rates are project specific and obtained via Bauder Technical.
  • Bauder Bitumen Blue Roof Flow Restrictor. The Bauder Bitumen Blue Roof Flow Restrictor is designed to be used in conjunction with a standard Bauder Bitumen Blue Roof Vertical Outlet DN70. The Bauder Blue Roof Bitumen Flow Restrictor is comprised of four parts; Baseplate, overflow pipe, Baseplate inner and Baseplate outer seal. The polyamide Baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE Overflow slots into the central hole of the Baseplate with an inner EPDM seal preventing any leaks. Baseplate has a number (1-12) of 10m m restrictive flow holes bespoke to the project. Bauder must be consulted to carry out this bespoke design.
  • Bauder Parapet Emergency Overflow Stainless Steel DN70: Emergency overflow/ tell-tale.
