round window arch

A round window arch is an arch element that frames the upper part of a window opening finished with a semicircular curve. Placed on the upper edge of the window, it emphasises the opening and gives the facade an orderly line; it is usually used together with a window casing. It is preferred both on interior windows and on exterior facades. Round window arches made from polyurethane are lightweight and mount easily and quickly above the window. They resist moisture and impact, do not crack or swell, and can be painted; they do not change shape under exterior weather. Polure produces round window arches in curve radii suited to the opening width, providing a frame compatible with the casing.
