Kawneer has launched the AA720 SL (Slimline) casement window as the latest addition to its AA720 range of windows and doors, and suites with the AA100 and AA110 curtain wall, 451PT framing and door systems.
An open-out window based on a BRE Green Guide A-rated frame, it is designed with 62mm sightlines.
The window is available with two vent style options. The AA720 SL Standard casement with overlapped vent offers a more conventional window design, with slim frame sections aimed at the education sector. The AA720 SL Double Flush casement, with flush frames both externally and internally, carry the contemporary aesthetic through to the inside of the building, making it suitable for the home improvement sector.
Both style options are independently weather performance tested to BS 6375-1: 2015 and achieve Class 4 (600 Pa) air permeability, Class 9A (600 Pa) watertightness and Class E2400 (2400 Pa) wind resistance.
The AA720 SL features a multi-chamber polyamide thermal break, offering single and dual-colour options and ensuring compliance with Document L. The casement is available as a top-hung or side-hung window with the side-hung option available with easy-clean egress hinges that enable simple and practical window maintenance from inside the building.
Internal glazing for both vents and fixed lights is more cost effectively achieved without the use of reverse glazing adaptors. A range of various high-performance cill options and corner posts for bays and conservatories suit virtually any configuration.
Capable of accommodating glazing up to 42mm for both new-build and refurbishment residential and heritage applications, the AA720 SL window has also been fully tested to PAS 24 enhanced security certification and is Secured by Design approved.
