Window Types for Your Chicagoland Home
Choosing the right window style for each room optimizes ventilation, natural light, aesthetics, and energy efficiency. Here's how each type works and where it fits best.
Double-Hung Windows
The most popular residential window style. Both upper and lower sashes slide up and down, and both tilt inward for easy cleaning from inside. Classic, versatile look that works in every room. Best for: bedrooms, living rooms, dining rooms, and any room facing walkways (nothing protrudes outward when open).
Casement Windows
Crank-operated windows that hinge on one side and swing outward. The compression seal creates the tightest air seal of any operable window — excellent energy efficiency. No center rail means unobstructed views. Best for: kitchens (above sinks), bathrooms, and anywhere maximum ventilation and air-tight sealing are priorities. Casement vs double-hung comparison →
Bay & Bow Windows
Bay windows project outward with 3 panels (center + two angled sides). Bow windows use 4+ panels in a gentle curve. Both add interior shelf space, dramatic light, and significant curb appeal. Best for: living rooms, dining rooms, and master bedrooms. Complete bay & bow guide →
Picture Windows
Fixed (non-opening) windows that maximize glass area and views. Often used as center panels flanked by operable casements or double-hungs. The most energy-efficient window type since there are no moving parts or seals to fail. Best for: living rooms with views, above kitchen sinks paired with casements, and transom applications above doors.
Sliding Windows
One or both sashes slide horizontally. Wider than tall, making them ideal for openings where height is limited. Best for: basements, above counters, and wide openings in contemporary designs.
Awning Windows
Hinged at the top and swing outward from the bottom. Can stay open during light rain without letting water in. Best for: bathrooms, basements, and paired above or below other windows for additional ventilation.
