Polyurethane Arch Types

Polure arch types cover the different forms and sizes of polyurethane arches used over doors and windows. Semicircular, flat-curve, wide-span and narrow-span arches fall within this group; they are chosen according to the width of the opening and the style of the space. The polyurethane material is lightweight and fixed directly to the wall with construction adhesive; it resists moisture and impact, does not crack or swell and can be painted. Unlike a wood arch it is unaffected by humidity, and it is lighter than plaster. Because each type is mould-cast, the curve and profile detail stay identical across pieces. Polure produces arch types in different span, curve-height and profile options.
