Description

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

Bauder Total Roof System (BTRS) 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. For green roof situations, please see Bauder Total Green Roof System (BTGRS).

See BBA certification 10/4744. BTRS can meet current UK Building Regulations Part B for external fire protection, and can feature torch-free and safe to torch installation on combustible details.

Key features:

  • Capping sheets 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.
  • Can satisfy requirements of Part B of Building Regulations.

Torch-Free/ Safe to Torch Zone Detailing:

Bauder was the first manufacturer to pledge its support to the Safe2Torch initiative, introduced by the National Federation of Roof Contractors (NRFC) in July 2017. The torch-free detailing designs specifically deliver secure and safe installations in the vicinity of combustible construction materials located on, or connected to, the roof such as timber substrates or upstands; abutments to cladding, roof tiles, slates or thatch; or debris such as dry leaf material that is at risk from ignition.

Torch-free detailing can be integrated into all bituminous waterproofing solutions to give versatile, safe installation techniques for all roof types, site conditions and budgets.

The waterproofing flashing should be turned up by at least 150 mm around features such as rooflights, parapets and service pipes passing through the roof, detail work to upstands, edge details, flashings, etc. The membrane should not be taken up in one piece. Consult Bauder for further information.

Key features of Torch-Free/ Safe to Torch Zone Detailing:

  • Complete range of self-adhesive bitumen membranes.
  • Installation follows industry best practice and conforms to BS 8217: 2005.
  • 4.2 mm-thick elastomeric KSO SN and KSO P-SN cap sheets.
  • Hot air welding of membrane laps in the torch-free zone.
  • Complies with Building Regulations Approved Document B – Fire Safety.
  • Manufactured to BS EN 13707: 2004 Reinforced Bitumen Membrane Sheets.

Benefits:

  • Reduces risk of fire caused by installation.
  • Practical solution so that installation programme times are achievable.
  • Robust waterproofing without compromising system longevity.

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 70 mm 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 10 mm 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.

- 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.
