round arch casing piece

A round arch casing piece is a decorative frame element that wraps the arch line and edges of a door or window finished at the top with a semicircular arch. Following the curve of the opening, it gives the upper section a continuous profile and, joined with vertical casings, emphasises the opening as a whole. It is used indoors and on exterior facades. The round arch casing piece made from polyurethane is lightweight, which makes installation at height easier. It resists moisture and impact, does not crack or swell, and can be painted; it is unaffected by damp. Polure produces the round arch casing piece so that the curve radius and profile section stay consistent, ensuring a clean joint with the vertical pieces.
