The Spectus French Casement Window delivers a classic continental style that is perfect for recreating traditional timber window designs. The system can be used for French-style and double-opening casements. Unlike a traditional casement window, the French Casement Window doesn’t have a central mullion. This intelligent design means it provides unobstructed views and enhanced ventilation when open.
