The ThermalHEART™ sliding door installed in Western Australia


thermalheart sliding


The Designer Series ThermalHEART sliding™ door system offers excellent thermal performance and stacking door configurations of up to 4 panels in each direction. The clean, bold frame design gives a modern aesthetic and integrated screening options are available.

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 awning™ is 32% more efficient than a standard non-thermally broken window.
    • A major advantage with ThermalHEART™ in cold climates is the reduction in internal condensation. ThermalHEART™ is also suitable for hot climates.
    • ThermalHEART™ will accept insulating glass units up to 32mm thick. The typical IGU thickness is 24mm.
    • We offer ThermalHEART™ in a range of stocked colours including dual colour Clear MIST™.
    • The door panels run on heavy-duty double bogey wheels as standard.
    • For the ultimate finish, the perimeter frame has snap-in flat fillers to close off all unwanted recesses. These fillers are isolated to prevent thermal transmission from inside to outside.
    • The flat sill is ideal for recessing into the floor finish.
    • This sliding door has been tested for compliance with the relevant Australian Standards and achieved a high water resistance of 300Pa; this makes the product suitable for most residential applications. We also tested the maximum size door panels and ran them through to destruction to make sure.
    • Low air infiltration suitable for air-conditioned buildings.
    • The extra strong door stiles allow large door panels to be fabricated.
