Plastomeric membrane for use as a direct waterproofing overlay to existing substrates, or as a system element of the robust Proteus built-up roof system, incorporating Proteus Pro-Therm insulation.
Plastomeric membrane for use as a direct waterproofing overlay to existing substrates, or as a system element of the robust Proteus built-up roof system, incorporating Proteus Pro-Therm insulation.
Features and benefits:
Proteus Pro-Felt® Torch-On cap sheets are installed with a roofing torch, onto a Proteus Pro-Felt® Underlay. Ensure the membrane is fully bonded. 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. The membranes are to be laid down the line of any slope. The lap-joints should not form a water check.
