A reinforced bituminous membrane roof waterproofing system.
Proteus Pro-Felt Endura is ideal for use as a fully bonded roof waterproofing and AVCL in a warm roof waterproofing system on flat and pitched roofs with limited access. Where traffic over this is envisaged, such as pedestrian access roofs, additional protection must be provided.
Proteus Pro-Felt Endura is a roof system including a self-adhesive air and vapour control layer (AVCL) which can be safely and securely bonded to any roof deck without the use of a torch. Thermal insulation is then bonded to the AVCL, followed by a polymer-modified, self-adhesive underlay and a torch-on cap sheet.
The Proteus Pro-Felt Endura Mineral cap sheet is a torch-applied, bituminous cap sheet which is saturated and coated with SBS (Styrene-Butadiene-Styrene) modified bitumen. It has a high tensile polyester fleece reinforcement, a thermofusible polyethylene film on the underside and a slate surfaced finish. The product also incorporates a special graphite additive within the membrane to provide enhanced fire performance properties.

Manufacturer guidanceThe membranes and AVCLs can accept, without damage, the foot traffic and light concentrated loads associated with installation and maintenance. Where traffic over this is envisaged, such as for maintenance of lift equipment, a walkway must be provided (for example, using concrete slabs supported on bearing pads, or an additional sacrificial layer of capsheet). Reasonable care should be taken to avoid puncture by sharp objects or concentrated loads. |
Ancillary items | Manufacturer guidanceRefer to manufacturers guidelines for mechanical fixing detail and vertical work higher than 300 mm, and insert requirements. |
Surface protection | Manufacturer guidanceThe membranes and AVCLs can accept, without damage, the foot traffic and light concentrated loads associated with installation and maintenance. Where traffic over this is envisaged, such as for maintenance of lift equipment, a walkway must be provided (for example, using concrete slabs supported on bearing pads). Reasonable care should be taken to avoid puncture by sharp objects or concentrated loads. |
System accessories | Not required.Membrane walkways.Roof membrane perimeter trims.Termination bars.Angle fillets.Outlets.Rooflights.Manufacturer guidanceConsult manufacturer for further details. |
Execution | Manufacturer guidanceConsult manufacturer for execution requirements. |
