New 70mm alumminium window
Aluk has launched its new C70S 70mm window, the big brother to its 58BW window system.
“The C70S has all the clean lines, slim sightlines and advanced functionality which customers love about the 58BW, but with increased weather performance and new design features for even faster fabrication and installation,” the company said.
Assembly is quicker, thanks to clip-together detailing on the sub sill, frame extenders, and Z adapter. A universal EPDM carrier groove means that the EPDM strip can be fitted easily using an Aluk-supplied snap-in PVC profile.
Fabricators also have the option to use crimped or mechanical corner cleats.
For installers, the system allows for reversed glazing without the need for a frame reverser, making it ideal for glazing at height, and it is available in a wide choice of configurations including side and top hung casements and TBT windows.
The C70S meets and exceeds all the key thermal, acoustic and performance criteria laid down by commercial specifiers, and opens up new opportunities for customers targeting both residential and commercial projects, the company said.
The C70S can achieve U-values of between 1.1W/m2K with triple glazing and 1.3W/m2K with double glazing. It also comes with options, in terms of glazing and foam insulation strips, which give fabricators the flexibility to design U-values either up or down to suit the specification of each project.
It also boasts ‘class-leading’ wind (600Pa) and water tightness (1,500Pa) performance, even with large span window openings, and has the option of 50mm acoustic glazing, which means it can be used everywhere from exposed coastal settings to noisy city centre locations.
Both inward and opening windows have been tested to PAS24 and accredited to SBD.
Marketing director Sioned Roberts said 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 they already enjoy with the 58BW.
One advantage of the C70S is that it shares the sightlines and many of the parts and tooling required to manufacture the 58BW.
“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,” she said.
