Aluminium KC51 Slim Casement
Aluminium Windows
The KC51 windows suite is a comprehensive collection of aluminium window systems compatible with new-build and renovation projects. KC51 windows are available with either 51mm or 75mm sub frame. They feature a mechanical corner cleat for easy and fast fabrication and can be used for composite, ribbon, and punched hole applications.
Aluminium windows manufactured using the KC51 system provide outstanding levels of weather protection. A range of opening configurations can be incorporated into the window’s design including wide opening systems for easy cleaning access. An integral drainage system is used to remove any water build up onto either a cill section or advanced face drain cap. Trickle vents can be incorporated into the system’s design in line with current building regulations and the window can be glazed from either the interior or exterior.

Innovation and aesthetics united in a single system. KC51 Slim Casement window mixes a modern and contemporary appearance with optimal technical features, especially its safety and energy saving benefits.
