curved window arch

A curved window arch is a polyurethane decorative frame piece applied to the top edge of a window opening, with an arched or curved top line. It turns a straight window head into an arched look or frames an arched window opening. It is used to emphasise windows both indoors and on building facades. The polyurethane material is lightweight and is fixed above the window with construction adhesive; it resists moisture, sun and impact, will not crack or blister, and can be painted. Being lighter than stone or plaster, it is easy to install in high positions on the facade and adds no extra load. Since it is mould-cast, the arch curve and profile stay the same on every piece. Polure produces curved window arches in sizes suited to different window widths.
