Equus Soprema TPO-Therm Warm Roof System
Description

The Equus Soprema Flagon TPO-Therm Warm Roof System is a light-weight, thermally insulated roofing system consisting of the Flagon TPO single layer membrane applied over a thermal insulation board and vapour barrier. A warm roof system guarantees a continuous and efficient thermal resistance (R-value) as per the New Zealand Building Code's H1 requirements. This system is designed for us on exposed flat roofs and decks.

Flagon TPO-Therm provides a UV resistant, puncture resistant membrane, that is installed with adhesive and hot air meaning a totally flameless installation for the residential and commercial industries. With an aesthetically pleasing colour of a darker grey than traditionally found in the NZ TPO market, or a sand grey with a higher solar reflectance, the system is suitable for a range or locations. This roofing system is a suitable solution for all areas of the country and can be installed over a concrete, plywood or metal substrate.

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.
