round curved arch

A round curved arch is an arch type that crowns the top of an opening with a soft curve close to a semicircle. It is used over door, window, or passage openings and gives the space a circular transition line. It offers a more flowing look than flat lintels and is usually applied together with a casing. Round curved arches made from polyurethane are lightweight, which makes installation at height easier. They resist moisture and impact, do not crack or swell, and their surface can be primed and painted. Unlike wood they are unaffected by damp, and they are more durable than plaster. In producing round curved arches Polure ensures the curve radius and profile depth come out correctly, offering pieces suited to different opening sizes.
