above-door arch models

Above-door arch models refer to the different forms and profile options of the polyurethane arch pieces applied above a door. They include semicircular arches, shallow (segmental) arches, keystone arches and profiled arches. They are used at interior and exterior door entrances to give the area above the door an arched look. The polyurethane material is light and applies directly with assembly adhesive and screws; it resists moisture and impact, does not crack or swell and can be painted. Being lighter than plaster makes above-door installation easier, and unlike wood it is unaffected by moisture. Because it is mould-cast, each model's detail repeats identically across pieces. Polure produces above-door arch models in a range of radii and forms.
