Compare casement, double-hung, sliding, bay, picture, and awning windows. Find the ideal window style for every room based on ventilation, views, and functionality.
Casement windows are ideal for kitchens because they crank open outward, making them easy to operate even over a counter or sink. They provide excellent ventilation and seal tightly when closed. Awning windows are another great kitchen option since they can stay open during light rain without letting water in.
In a single-hung window, only the bottom sash moves up and down; the top sash is fixed. In a double-hung window, both the top and bottom sashes slide vertically. Double-hung windows offer better ventilation (you can open top and bottom simultaneously for airflow) and are easier to clean since both sashes tilt inward. Double-hung windows typically cost 10-20% more than single-hung.
Picture windows are best for rooms where you want to maximize natural light and views without needing ventilation -- such as living rooms with a scenic view or above a staircase. Because they don't open, picture windows are the most energy-efficient and airtight option. They are also typically the most affordable per square foot of glass area.
Yes, bay windows can make small rooms feel larger by projecting outward from the wall, adding both visual and actual floor space. A typical bay window extends 12-24 inches from the exterior wall. They flood the room with light from three angles and can create a cozy window seat or display area. However, they do require adequate exterior clearance.
Casement windows provide the best ventilation because the entire sash swings open, exposing 100% of the window opening to airflow. By comparison, double-hung and sliding windows only expose about 50% of the opening since one sash overlaps the other. For maximum airflow, install casement or awning windows on opposite walls to create cross-ventilation.
