Torch-on reinforced spunbond polyester elastomeric bitumen membrane for use as an underlay or VCL to high performance Proteus capsheets and as part of Proteus roofing systems.
Application
- To be used as an under-layer in conjunction with Proteus Pro-Felt® built-up roof systems and Proteus Pro-Felt® capsheets.
- To be used as a VCL layer on concrete decks.
- Proteus Pro-Felt® capsheets are available with a sanded or mineral finish, and suitable for both refurbishment and new build projects.
Description
Torch-on reinforced spunbond polyester elastomeric bitumen membrane to be used as an underlay or VCL to high performance Proteus capsheets and as part of Proteus Pro-Felt® overlay systems and the Proteus built-up roof system range.
Features and benefits:
- Manufactured in Europe.
- Designed to provide high performance at extreme temperatures at high altitudes.
- Retains its high elastomeric ability and performance and ensures the roof is protected by a durable and lasting waterproofing membrane.
- 4.05 kg/m² with high tensile strength.
- SBS (styrene-butadiene-styrene) modified bitumen.
- Thermofusible film.
- Polypropylene finish.
- The range includes flame-free, self-adhesive layers.
- Bespoke specifications available; consult manufacturer for details.
To be installed by torch-application to the underside of the membrane. Ensure the underside is heated to a sufficient level and is soundly adhered to the substrate. All lap joints must be completely sealed, with a continuous 5 mm bitumen bead extruding from all laps. Side laps to be a minimum of 80 mm. End laps a minimum of 100 mm.
