Double-Hung vs. Casement Windows for South Carolina Homes

When people in South Carolina start planning a replacement, double-hung and casement windows are often the two styles that make the shortlist. Both work, but they behave very differently once summer heat, moisture, and seasonal storms enter the picture.

The better choice depends on the home, the room, and how the windows get used. A ranch house, a historic property, and a newer build near the Congaree River may all point in slightly different directions.

Double-hung windows open vertically with two movable sashes, while casement windows swing outward from side hinges. That basic difference affects airflow, cleaning, weather sealing, and long-term maintenance.

Weather exposure should stay in the conversation. If a property is vulnerable to heavy rain, wind, or flying debris, people often look at impact-resistant windows for severe storms SC Midlands or tornado-resistant windows Lexington County SC, and the operating style is only one piece of that decision.
