Polyurethane Surround Arch

A polyurethane surround arch is an arched polyurethane surround element that wraps the top of a door or window opening in a curved form. It is used to create a curved transition at the top point of a straight surround profile and give the opening a classic arch look. Polyurethane is light and is applied to the surface with mounting adhesive or screws; it resists moisture and impact, will not crack or swell and can be painted. Because it withstands moisture on the exterior, it offers the same durability as the surround. Because the arch curve is mould-cast, the radius and section stay standard and join smoothly with the side surrounds. Polure produces surround arch elements in a range of radii and sections.
