Which Window Style Is Right for Your Wilmington Home?
The best window style depends on your home's layout, ventilation needs, and aesthetic goals. DNA Roofing and Siding offers styles suited to the older rowhomes and colonials in Wilmington's historic districts as well as newer construction throughout New Castle County.
Double-Hung Windows
Double-hung windows are among the most popular choices for Wilmington homeowners. Both sashes tilt inward for easy interior cleaning and provide flexible ventilation control suited to Delaware's variable spring and fall temperatures.
Casement Windows
Casement windows are hinged on one side and open outward with a crank. They form a tight seal when closed, which may help reduce air leakage, and they work well where maximum ventilation or unobstructed views are priorities.
Bay and Picture Windows
Bay windows extend outward from the wall and add architectural interest to older homes and bungalows. Picture windows provide a large, unobstructed pane and are often paired with operable styles to balance light and airflow.
