The Equus Soprema Duotherm Warm Roof System is a light-weight, thermal roofing system which consists of the DuO two-layer membrane system applied over a rigid thermal PIR insulation board and vapour barrier. This guarantees a continuous and efficient thermal resistance (R-value) as per the New Zealand Building Code, and is designed for use on exposed architectural flat roofs, podium decks, balconies, and terraces. It offers a cost effective, superior, thermal waterproofing system.
Duotherm Warm Roofs provides a hard, stable, UV-resistant, and flexible modified bituminous membrane, 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 the DuO Membrane 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, concrete and metal substrates.
