Features and benefits:

• Designed with more than 35 years of folding door experience.
• Slender 55 mm frame depths, narrow 115 mm sightlines and a choice of either low-threshold or fully weathered tracks.
• Offers an ultra-smooth, effortless operation on doors that can open inwards or outwards and that include exclusive panel catch technology.
• Manufactured with multi-point locking to meet the requirements of PAS 24:2016 and the Secured by Design™ police preferred specification for security.
• Independently tested to severe weather rating standards to achieve 900 Pa water tightness* and 600 Pa air permeability*.
• Thermal performance, with overall system U-values from 1.4W/m²K†.
• Locking panel catch holds the lead door of the system in place when the doors are being opened, preventing the door from swinging shut.
• Stacking clip holds the doors securely in place when they are stacked open, stopping the wind (or young children) closing the doors unexpectedly.
• Patented 24 mm polyamide thermal break.

* Water tightness and air permeability test performance is dependent upon a number of factors including system configuration and panel sizes.

† Thermal performance achieved is dependent on glass specification.
