classical architectural arch

A classical architectural arch is an arc-shaped decorative element that frames the upper part of door, window, or passage openings. In classical architecture it is used to emphasise the tops of openings and shape transitions, and indoors it is applied above niches and entrances. Arches made from polyurethane are lightweight, easier to handle than stone or plaster versions, and fitted with construction adhesive. They resist moisture and impact, will not crack or swell, and can be painted. Because they are mould-cast, the arch profile and surface ornamentation stay identical on every piece, ensuring a match across symmetrical openings. Polure produces classical architectural arches in a range of spans and heights for use above doors and windows.
