Ancestral wood window

The ancestral window, also known as an espagnolette window, is a perfect match for any heritage home. Resulting from a happy marriage between period design and current technologies, it combines beauty with prestige and charm of yesteryear.

In addition to having all the advantages of the conventional casement window, it offers a multitude of options such as a hinge and cremone hardware system, sashes that open fully on the inside for optimal ventilation, very easy maintenance and quick sash removal.
