Equus Soprema Sopratherm Warm Roof System
Description

The Equus Soprema Sopratherm Warm Roof System is a light-weight, thermal roofing system consisting of the Soprasun Plus two-layer waterproofing membrane system torch-applied over thermal insulation board and a vapour barrier. Sopratherm guarantees a continuous and efficient thermal resistance (R-value) as per the NZ Building Code and is designed for use on exposed flat roofs and decks. The Sopratherm system is CodeMark certified and BRANZ Appraised.

Sopratherm roofing offers a UV resistant, modified bitumen membrane (APP) finished with coloured slates, providing protection against the demanding local weather conditions, and an attractive grey finish. The modified bitumen membrane also retains a high softening point, which allows for a more forgiving membrane during installation in hot conditions.

With a standard base sheet and cap sheet suitable for the NZ climate, Sopratherm can be used on a range of substrates to form an efficient warm roof system in any area across the country.

Key Features

Advantages of Choosing a Warm Roof

  • Specific project design with condensation risk analysis (CRA) and wind load calculations to ensure the best system available for the buildings 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, causing less penetrations in the membrane.
  • Energy Cost savings are maximised 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.
