A unique slimline aluminium casement window that delivers superior form and function has been launched by leading UK manufacturer Kawneer.
The AA®720 SL (Slimline) casement window is the latest enhancement to Kawneer's premium AA®720 range of windows and doors, and suites with the AA®100 and AA®110 curtain wall, 451PT framing and door systems.
A high-performance open-out window based on a BRE Green Guide A-rated frame, it is designed with ultra-slim 62mm sightlines which maximise the glazing vision area while also giving a modern aesthetic look, providing optimum weather and thermal performance. The AA®720 SL window is available with two vent style options.
The AA®720 SL Standard casement with overlapped vent offers a more conventional window design, with slim and elegant frame sections, as a cost effective and robust solution ideally suited for the education sector.
The AA®720 SL Double Flush casement, with unique flush frames both externally and internally, carry the sleek contemporary aesthetic through to the inside of the building, making it ideal 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 AA®720 SL features a multi-chamber polyamide thermal break, offering single and dual-colour options and ensuring superior thermal efficiency and full 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 AA®720 SL window has also been fully tested to PAS 24 enhanced security certification and is Secured by Design approved.
