KC75 Casement
Aluminium Windows
The KC75 aluminium casement window system from Exlabesa leads the field in terms of both performance and slimline appearance. It is compatible with both new-build and refurbishment projects and thanks to its innovative design using a mechanical corner cleat, can be quickly and easily fabricated to meet tight installation deadlines.
KC75 casement windows can be used in top hung and side hung applications. Polyamide thermal breaks are used to optimise thermal efficiency with an outstanding weather resistance. The system can be used for punched hole, composite, and ribbon window applications and can be dry glazed either internally or externally using clip-in beads.

Aluminium windows make a stunning statement in any home. KC75 aluminium windows have slim frames that maximise the amount of natural light, making them perfect for both traditional and modern homes.
With a choice of design options, this system comes with a multitude of practical features for today’s modern day living, while exceeding the energy performance requirements of current Part L Building Regulations
