Flexible U-Values to suit specification and budget

Flexible U-Values to suit specification and budget

AluK’s new C70S aluminium window system offers U-Values as low as 1.1W/m2K with triple glazing and 1.3W/m2K with double glazing, and also comes with three different foam insulation options, giving specifiers the flexibility to design U-Values up or down to suit the specific performance and budgetary requirements of each project.

Designed with all the versatility required for low, mid and high-rise applications in both residential and commercial projects, the C70S delivers what AluK call ‘a winning combination of high performance and impressively slim sightlines’.

It boasts class-leading wind (600Pa) and water tightness (1500Pa) performance, even with large span top hung window openings and can accommodate 50mm acoustic glazing, making it suitable for use everywhere. This system has the same slim 89mm sightlines and extensive range of colour options as AluK’s hugely popular 58BW window, enabling specifiers to mix and match the systems to achieve a uniform aesthetic across a broad range of applications.

It has also been engineered with a number of innovative design and installation features which AluK says make it a practical and stylish choice. That includes a concealed coupler option to provide mullion support without compromising on sightlines, and a Z adapter profile to achieve reversed glazing fixed lights with less material cost. It also has a sub cill profile for press metal, which can be added after window installation to avoid damage during construction and a paint matched aluminium cover strip added which conceals easy-access fixings.

Available in a wide choice of configurations including side and top hung casements and TBT windows, the C70S is hugely practical with a range of ancillaries and couplers for installation alongside doors and curtain walling. Both inward and outward opening windows have been successfully tested to PAS24 for security making the C70S suitable for all projects requiring Approved Document Q compliance.
