C70S Window System

AluK GB Ltd

AluK has launched its brand new C70S aluminium window system, designed to suit light commercial projects of all varieties. Engineered to the highest UK standards, the C70S delivers an attractive combination of high performance and impressively slim sightlines.

• Impressive thermal performance
• Exceptional water and air performance
• Up to 50mm glazing capacity
• Maintain sightlines with reversable rebates
• Post-installation sub cill profile for press metal

This new 70mm system offers market leading U-Values as low as 1.1W/m2K with triple glazing and 1.3W/m2K with double glazing, but it also comes with three different foam insulation options so that specifiers have the flexibility to design U-Values either up or down to suit the specific performance and budgetary requirements of each project.

The C70S boasts outstanding water tightness (1500Pa) and wind performance (600Pa), even with large span top hung window openings and can accommodate 50mm acoustic glazing, making it suitable for noisy urban environments.

Available in Top Hung, Side Hung, Tilt & Turn, and fixed light configurations, the C70S is hugely practical with a range of ancillaries and couplers for installation alongside doors and curtain walling.

The system has the same slim sightlines as AluK’s hugely popular 58BW window, enabling specifiers to mix and match systems to achieve a uniform aesthetic across a broad spectrum of applications. Both inward and outward opening windows have been successfully tested to PAS 24 for security, making the C70S suitable for all projects requiring Approved Document Q compliance.

Innovative design and installation features include a concealed coupler option to provide mullion support without compromising on sightlines, a Z adapter profile to achieve reversed glazing fixed lights with less material cost, and sub cill profile that can be added after installation to avoid damage.

The C70S is available in AluK’s extensive range of highly durable, powder-coated colours and finishes, with white, grey and black single and dual-colours available from stock.
