Kawneer has launched the GT70S Slimline Renovation window system with heritage-styling aimed to replicate the look of steel.

GT70S is an open-in window that can be used for composite and ribbon windows and offers a range of structural and coupling mullions and a glazing infill up to 64mm for greater design and performance variation.

The system uses a multi-chamber thermal break core for thermal efficiency and full compliance with Approved Document L and Scottish Building Standards Part 6. It is available as a tilt before turn or turn only window and uses polyamide thermal break offering single or dual colour options. 

It is suitable for composite and ribbon windows, available as a tilt before turn or turn only window. A range of structural and coupling mullions are available. It features concealed drainage system to enhance a building’s aesthetics.

Optional bevelled designed feature caps can add a sculptured effect to the external surface of a building.

Weather performance is tested to: Air Infiltration (BS EN 12207): 600 Pa, Watertightness (BS EN 12208): 600 Pa, Wind Resistance (BS EN 12210): 2400 Pa (Windload)* and 1750 Pa (Safety)*.

The window is independently tested by a UKAS accredited testing authority to PAS 24:2016.
