Description

Total bitumen inverted roof system, incorporating inverted insulation, and 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).

Bauder Inverted Roof systems should be ballasted/ landscaped to prevent wind uplift and/ or floatation. Type, thickness, weight of landscaping should be agreed with Bauder per bespoke project basis.

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.
  • Can comply 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.
