    Key Features

    • Series 731 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™ door is 32% more efficient than a standard non-thermally broken door.
    • A major advantage with ThermalHEART™ in cold climates is the reduction in internal condensation. This saves potential damage to timber reveals and floor finishes.
    • ThermalHEART™ is also suitable for hot climates – ThermalHEART™ Windows and Doors will help to reduce the cooling load on airconditioning units in hot climates.
    • We offer ThermalHEART™ in a range of stocked colours including dual colour ClearMIST™ (Clear anodised external with Surfmist powder coat internal).
    • The doors have been tested for compliance with the relevant Australian Standards and achieved a high water resistance of 300Pa, making the product suitable for most residential applications.
    • Low air infiltration makes the product suitable for airconditioned buildings.
    • The extra strong door stiles allow oversize door panels to be fabricated.
