Key Features / Performance Characteristics

  • Series 730 bi-fold door incorporates ThermalHEART™ technology giving a true wide thermal break between the outside and inside faces. WERS (Window Energy Rating System) data shows that using the same IGU in a ThermalHEART™ Bi-fold door is 32% more efficient than a standard non-thermally broken Bi-fold door.
  • A major advantage with ThermalHEART™ bi-fold doors in cold climates is the reduction in internal condensation. This saves potential damage to timber reveals and paint finishes. ThermalHEART™ is also suitable for hot climates.
  • We offer ThermalHEART™ in a range of stocked colours including dual colour ClearMIST™, contact your local Vantage fabricator for details.
  • Running bi-fold doors on bottom rollers reduces the problems caused by lintel sag and allows us to offer optional highlights.
  • This bi-fold door has been tested for compliance with the relevant Australian Standards and achieved a high water resistance of 380Pa. This makes the product suitable for most residential applications.
  • Low air infiltration, makes this bi-fold door suitable for airconditioned buildings.
