Casement vs Double-Hung Windows: Which Is Right for Your Home?

Choosing between casement and double-hung windows is one of the most common decisions during a window replacement project. Both are excellent — but they serve different purposes.

Double-Hung Windows

The classic choice. Both upper and lower sashes operate (slide up and down), and both tilt inward for easy cleaning from inside. Double-hung windows are the most popular residential window style in Chicagoland for good reason: they're versatile, traditional-looking, and work in virtually every room.

Best for: Bedrooms, living rooms, dining rooms, and any room where you want a classic, traditional look. They're also ideal for rooms facing walkways or porches because nothing protrudes outward when open.

Casement Windows

Crank-operated windows that hinge on one side and swing outward. When closed, the sash presses against the frame with a tight compression seal — making casement windows the most air-tight operable window style available. No center rail means unobstructed views.

Best for: Kitchens (especially above sinks where reaching a double-hung is awkward), bathrooms, above counters, and any location where maximum ventilation and air-tight sealing matter. Also excellent for contemporary and modern home designs.

Mixing Styles

Most Chicagoland homeowners use a combination — double-hung in living spaces for a traditional look, casement in kitchens and bathrooms for ventilation and ease of operation. We often use picture windows flanked by casement windows for a dramatic combination of maximum light and maximum airflow.

Energy Performance

Casement windows have a slight edge in energy efficiency because the compression seal creates a tighter barrier than the sliding seals on a double-hung. However, modern Andersen double-hung windows with proper weatherstripping and multi-point locks have closed this gap significantly.
