DuO Two Layer Membranes


DuO Two Layer Membranes

The Equus Soprema DuO Two Layer Roofing System is a two-layer torch applied membrane designed for use on exposed architectural flat roofs, podium decks, balconies, and terraces. It offers a superior waterproofing system that is both UV resistant and flexible.

DuO roofing membrane provides a hard, stable, UV-resistant, and flexible modified bituminous product, finished with pressed coloured natural slates to provide an aesthetically pleasing finish. The roofing system is suitable for both new builds, and roof refurbishments.

The system has been assessed and complies with the New Zealand Building Code, and holds a current BRANZ appraisal.

The basesheet and capsheets used for each system are specifically selected based on the requirements of the project, including substrate, weather conditions, and use of the area. These include fully torched, no flame glue, mechanically fastened, and root resistant options.

This system can be used on plywood and concrete substrates to form a standard cold roof system.
