Polyurethane Arch With Jambs

A polyurethane arch with jambs is a polyurethane frame set where the straight jamb running along the door or window edge joins the curved arch above. Applied around window and door openings, it provides both the edge casing and the upper arch as a single unit. The polyurethane material is light and is applied directly to the wall with mounting adhesive; it resists moisture and impact, does not crack or blister and can be painted. When used on a facade, it is not affected by moisture and temperature change as much as plaster. Because it is cast in a mould, the jamb and arch profiles share the same section and pattern, so the joints sit cleanly. Polure produces matching polyurethane arches and jambs in compatible sizes.
