Exterior window arch
Exterior window arch refers to pre-curved high-density polyurethane exterior casing moldings engineered to frame arched window apertures across building facades. Adding classical depth and weather protection over window openings, polyurethane facade arches impose zero static load on exterior thermal insulation systems (EIFS) unlike cast concrete or stone trim. Impervious to freeze-thaw cycles, driving rain, and UV degradation without splitting or peeling.
