The EQUUS SOPREMA NOVATHERM Self-adhered Warm Roof System is a light-weight, thermally insulated roofing system which consists of the NOVA-SK self-adhered membrane system applied over a thermal insulation board and vapour barrier. This warm roof system 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 in the New Zealand climate.

NOVATHERM self-adhered is our only warm roof system to have a completely flameless installation making it a highly sought-after system where a torch-on membrane system is not desired. The NOVA-SK membranes have high self-adhesive properties, creating a robust watertight system for any warm roof design, and are finished with natural grey slates for an aesthetic, cost-effective solution for the building owner.

With a standard self-adhered base sheet and cap sheet suitable for the NZ climate, NOVATHERM can be used on plywood, concrete and metal substrates to form an efficient warm roof system in any area across the country.

* Economical price and good quality membrane

* Completely flameless installation

* Good durability and easy maintenance, with a life expectancy of 20 years in thel New Zealand climate.

* BRANZ appraised system

* Specific project design with condensation risk analysis (CRA) and wind load calculations to ensure the best system available for the building’s requirements.

* Condensation Control – A warm roof moves the dew point to the outside of the structure, ensuring there is no condensation build-up in the ceiling cavity.

* No condensation build-up negates the need for mechanical venting, caufing less penetrations in the membrane.

* Energy Cost savings are maximized with less need for heating or cooling throughout the building.

* Creates more space within the ceiling for services.

* Light-weight system, strong and flexible for resistance to seismic movement.
