AluK has unveiled its new C70S 70mm window as the big brother to its 58BW window system, with increased weather performance and new features for faster fabrication and installation.
Assembly is quicker, thanks to clip-together detailing on the sub cill, frame extenders, and Z adapter, and a universal EPDM carrier groove means that the EPDM strip can be fitted easily every time using a ‘snap-in’ PVC profile supplied by AluK.
Fabricators also choose crimped or mechanical corner cleats ensuring that the system can be integrated into any fabrication set up.
For installers, the system allows for reversed glazing without the need for a frame reverser, and it is available in a choice of configurations including side and top hung casements and TBT windows.
The C70S is said to meet and exceed all the key thermal, acoustic and performance criteria laid down by commercial specifiers. For instance, it can achieve U-Values of between 1.1W/m2K with triple glazing/ 1.3W/m2K with double glazing, and wind (600Pa) and water tightness (1500Pa) performance, even with large span window openings, and has the option of 50mm acoustic glazing.
Both inward and opening windows have been tested to PAS24 and accredited to SBD.
Marketing Director Sioned Roberts says that the C70S will be the platform on which AluK builds an entire new range of 70mm products, giving customers the same benefits of system integration which they already enjoy with the 58BW.
The C70S shares the sightlines and many of the parts and tooling required to manufacture the 58BW, she added. “This means customers can add the new system to their range without a significant increase in their stockholding and give themselves flexibility on project specifications.”
The C70S is available on five-day lead times from stock in white, grey, black and dual-colour white/grey and white/black options. Other colours and finishes are available to order.
