CS 24 -SL

Concept System 24 ‘Steel Look’ window

Ultimate elegance

Concept System® 24-SL is a thermally insulated system for outward opening windows that combines ultra-slim design, stability and ease in production. The system’s slender exterior contours and specially designed glazing beads give it a steel look & feel.

This in combination with the excellent insulation level makes CS 24-SL not only suitable for new-build houses, but also for renovations of steel-framed windows, residential constructions, schools and utility buildings.

The standard outward opening types can be applied in numerous combinations in line with the needs of the building. The window system perfectly matches the CS 24-SL door system. A unique aspect is that this slim system can also comply with burglar resistance class 2, offering a safe and secure solution.
