ThermalHEARTâ„¢ Awning Window | Series 726


This thermally broken frame and sash offers excellent thermal performance and demonstrates the dual colour capability of the Designer Series ThermalHearT™ range.
The frame and sash set the theme for a flat faced, square edged aesthetic common to all Designer Series products. Window mullions have internal stiffening boxes rather than external fins to also improve aesthetics.

    Key Features

    • Series 726 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. This saves potential damage to timber reveals and paint finishes.
    • ThermalHEART™ is also suitable for hot climates – thermally broken windows and doors will help to reduce the airconditioning load in a hot climate.
    • We offer ThermalHEART™ in a range of stocked colours including dual colour ClearMIST™ (Clear anodised exterior and Surfmist powder coat interior).
    • The window has been tested for compliance with the relevant Australian Standards and achieved a very high water resistance of 600Pa, this makes the product suitable for most applications including multi-storey apartments.
    • Very low air infiltration, makes the product suitable for airconditioned buildings.
    • The extra strong sash allows large sash windows to be fabricated for high wind load areas.
