The modern, minimal aesthetic of the 77 system means it is ideally suited to new-build settings, particularly multi-storey apartments where developers can achieve a uniform look.

The 77 system opens new opportunities for architects working right across the new-build market with a flat, square profile design which buyers and developers love. The open-in and open-out window profiles are both easily paired with the door, so it easy to create a coherent overall look throughout any size or scale of property with no compromise on light, views or sightlines.

The 77 system easily meets the 1.2 W/m2K U-Value limit set for Part L compliance in new-builds using standard, cost-effective 1.0 centre pane double glazing. If even lower U-Values are required, then it can also accommodate triple glazing to achieve as little as 0.8 Wm2K, which is the expected target in the 2025 Future Homes standard.

The system’s high performance extends beyond the thermal efficiency, however. It has now been given new glazing foams and centre seals to enhance the wind and water resistance and has passed the PAS24: 2016 security test to provide complete peace of mind.

Another part of the update are the new AluK Novae handle designs available in black, white and silver to suit any interior finish and décor, and additional hinge options including face fixed, slimline barrel or fully concealed for the ultimate contemporary look. A new mid-rail means doors can even now be fabricated with solid panels at the bottom if required in either single or double configurations.

The handle and hinge choices have also been deliberately designed to give plenty of freedom and flexibility to buyers while still being cost effective and easy to fit.
