The KS59 casement window system, renowned for its ultra-slim aluminium sightlines of only 70 mm, undergoes a transformative upgrade, expanding design possibilities and functionality. With the introduction of new sash options and a sleek flush frame, the KS59 sets a new standard in architectural elegance and versatility.

Flush outer frame available, and ultra-slim sight lines.

Originally conceived to offer a modern aesthetic to residential and commercial spaces, the KS59 now takes design flexibility to new heights. Building upon its distinctive appearance and performance, the updated system now offers three sash design options – flat, stepped, or chamfered – providing fabricators with a broader spectrum of styles, from modern minimalism to heritage and industrial-inspired designs.

In addition to the expanded sash options, the KS59 introduces a new flush frame choice, further enhancing its contemporary look. This sleek addition complements the existing casement aesthetic, offering architects and end homeowners even more design freedom to create visually striking spaces.

Suitable for almost any type of application, from residential to commercial, new build to refurbishment projects, the KS59 system maximizes the glass area, allowing natural light to flood interiors and creating a bright and inviting atmosphere.

Manufactured in Britain at the Exlabesa site spanning 9 acres in Doncaster, South Yorkshire, KS59 is fully compliant with British Building Regulations and meets PAS 24 strict security standards. It offers a Uw-value as low as 1,4 W/m²K and includes trickle bends adapted to meet Part F ventilation requirements.

Thanks to its innovative design using a transom screw port and mechanical corner cleat or crimping cleats, it can be quickly and easily fabricated to meet tight deadlines. Additionally, the system is compatible with a variety of accessories and add-ons, encompassing Georgian bars, bay pole, 90º corner, and flush add-ons of 20 and 40 mm.

With its cost-effective fabrication process and fabricator-friendly design, the KS59 is the optimal choice for those seeking a timeless and elegant window solution.

“We are thrilled to unveil the enhanced KS59 window system, which redefines what’s possible in architectural design,” said Simon Moore, Business Development Manager at Exlabesa. “With its ultra-slim sightlines, expanded sash options, and new flush frame, the KS59 empowers architects and designers to bring their creative visions to life while maintaining the highest standards of performance and security.”
