    The Optima French Casement Window adds a touch of continental style to a project and offers the ideal alternative to traditional timber window designs.

    Benefiting from the same features and benefits as the standard casement, the French Casement also achieves the highest energy rating and U-values and will also take 24mm or 28mm double glazing, and 36mm, 40mm and 44mm for triple-glazed windows.

    It’s also a very practical solution. It provides unobstructed views and opens to a full 90 degrees which makes it ideal for windows with smaller apertures or where an egress window is needed.
