PVCu
Kömmerling PVCu windows combine German engineering with designs to suit a wide range of British homes. From O70’s decorative curves and C70’s clean edges to the timber-inspired Flush 70, each style offers energy-efficient, low-maintenance frames with a choice of colours and woodgrain finishes to make them your own.
O70
O70 features softly curved, decorative detailing for a more traditional appearance. Its sculpted frame and glazing beads make it a natural choice for homes that suit a softer, classic window style.

C70
C70 features straight, chamfered edges for a cleaner, more contemporary appearance. Its understated detailing offers a simple, versatile alternative to O70’s decorative curves.

Flush 70
Flush 70 features opening sashes that sit level with the outer frame, creating a smooth exterior inspired by traditional timber windows. Its neat, balanced appearance complements both character properties and modern homes. A perfect upgrade from your current PVC windows.
