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

Bauder Total Roof System PLUS (BTRS PLUS) 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 PLUS (BTGRS PLUS), which has the option of using a root-resistant capping sheet.

BTRS PLUS system holds fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs, stated permutations of build-ups verified by the BBA are listed on our certification. BTRS PLUS is deemed ‘unrestricted’ and suitable for use on any part of a roof.

Flame-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.

Flame-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.
