Circle-Top Windows

Circle top windows are semi-circular windows installed above standard rectangular windows. Also sold by names such as "round top," "radius" and "geometric," these specialty windows add curb-appeal by lending a home's exterior a custom appearance. They also contribute charm by filling the interior with natural light.

1. What materials, colors and stains are available for circle-top windows?

Circle top windows come in the same variety as ordinary windows. Wood offers natural warmth and flexibility, because you can paint it any color. Popular wood finishes include pine, douglas fir, mahogany, oak, walnut and cherry. Clad wood presents as natural wood inside and blends nicely, while providing a low-maintenance exterior that holds up well to the elements. At the Madison County Hardware and Building Supply in Danielsville, Ga., a clad wood window costs only about 5 percent more than solid wood.

If cost is a concern, you might consider vinyl windows, which are affordable, low-maintenance and can be ordered to match existing windows. The only way to ensure a perfect match, however, is to order the circle top and other windows at the same time. Fiberglass and composite materials can be molded, allowing for unusual and creative designs.

2. How much do the brand names cost?

Pella, Jeld-Wen, Marvin and Andersen windows are comparable in terms of cost and popularity. According to the Andersen website, the 400 Series Circle Top Window with a clad wood frame, costs $669.00. Madison County Hardware and Building Supply in Danielsville, Ga. reports an equivalent Marvin window would cost about the same price. Lesser-known circle top windows tend to run $150-250 less.

When budgeting for your renovation and gathering estimates, keep in mind that circle top windows are more difficult to install and require special skills. Consequently, the installation price may be higher than with ordinary windows.

3. How energy efficient are circle top windows?

Circle top windows do not open, which make them more energy efficient than potentially leaky ventilating windows. To find the most efficient circle top windows, look for ENERGY STAR certification or the National Fenestration Rating Council (NFRC) label. The NFRC evaluates energy efficiency properties, by examining the whole window. According to the Efficient Windows Collective, products vary considerably. While technology like triple glazing can help, the total sum of a product's parts account for its efficiency.
