Why choose 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 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.
