Rounded windows come in many specialty designs, like full circles, quarter-round designs and arched tops over rectangular openings. These curved openings add a unique accent to a home's interior and exterior, softening and complementing more traditional, angular designs.

Some contractors install a half-circle sunburst at the top of oblong windows, turning an ordinary window into a decorative accent. Homeowners can select special, energy-efficient glass designs, grids or fabric treatments to allow the arch to stand out from the remainder of the window. For extra-tall openings, sunbursts are often mounted at the top of a standard double- or single-hung design.

Finding window coverings for round or half-arch styles can be challenging, but there are stores that specialize in these unique shapes. Homeowners may want to consider a half-arch fabric treatment on the bottom of a circular window, which offers privacy while allowing natural light to filter through the top. Other residents hang beads, ribbon or other materials from the top of a rounded frame to break up the pane in an unusual way.

To cover a rounded or arched opening quickly and economically, homeowners can buy a stick-on, simulated stained glass design until they find a treatment that they prefer.
