Application

Suitable for new build and refurbishment applications and can be used in warm, cold and inverted roof scenarios, including green roof applications.

Description

Bitumen warm roof system, incorporating torch-on bitumen capping sheet with self-adhered bitumen underlayer, insulation and self-adhered bitumen air and vapour control layer (AVCL).

Bauderflex Roof System 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. Includes the option of using a root resistant cap sheet, making this waterproofing system suitable for green roof situations.

See BBA certification 10/4744. Bauderflex 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.


Features and benefits:

  • Capping sheets with tensile strength up to 800 N/50mm.
  • 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 prevents spread of flame.
  • Heavy duty, robust and extremely tough.
  • Service life in excess of 30 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 manufacturer for further information.


Features and benefits 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, KSO ALP SN and KSO P-SN cap sheets.
  • Hot air welding of membrane laps in the torch-free zone.
  • Bauder polyisocyanurate (PIR) insulation bonded with polyurethane (PUR) adhesive in warm roof construction.
  • Can comply with Building Regulations Approved Document B – Fire Safety.
  • Manufactured to BS EN 13707: 2004 Reinforced Bitumen Membrane Sheets.
  • Reduces risk of fire caused by installation.
  • Practical solution so that installation programme times are achievable.
  • Robust waterproofing without compromising system longevity.

Preparation

-

Horizontal work

Bauder Activator-Primer (Canister) APR01.

Guidance for specification option:

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: Approximately 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 FBS); 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.

Air and vapour control layer

-

Type

KSD FBS.

Guidance for specification option:

Robust, self-adhesive elastomeric bitumen air and vapour control layer (AVCL), with a mica finished upper surface to allow easy bonding of insulation using appropriate Bauder Insulation Adhesive. One side lap features an 80 mm wide glass fleece along the underside, and a 100 mm strip of aluminium foil above. The other side lap has a thermofusible film on the top surface. This arrangement ensures that laps are heat sealed using hot air or gas torch as appropriate to extrude a bitumen bead, thus ensuring waterproofing integrity.
