Distinct Architectural Appeal

One of the earliest forms of windows, the casement has been around for centuries. Many historic buildings throughout Europe – some dating as far back as the 16th century – retain some form of their original casement windows. So, as it's often said, why reinvent the wheel?

REHAU has taken a tried and true window concept and evolved it into an elegant, high-performance design preferred by discerning homeowners, designers and architects in residential markets across the world. And while the casement may retain a distinctly European influence, this style window has in fact seen a sharp upward trend in residential installations across Asia in recent years.
