Top and bottom sashes slide up and down within the frame, allowing bottom to be closed while top is open to keep kids and pets safe. Not best option in extreme climates.
Sashes slide horizontally on a track. Works well when space is limited and good for rooms facing walkways, porches, and patios. Provides plenty of light and ventilation.
Hinged like a door and crank-operated. Provides great ventilation, air flow, and clear views to the outdoors with less air leakage than hung or sliding.
Hinged at bottom and can open inward or outward. Good above door or window, or in a basement for ventilation. Less air leakage than others since sash presses against frame.
Opens outward from a top hinge. Good space saver and among most energy-efficient because they seal well, but doesn’t allow for window AC.
Used for entrance ways, such as a front door, side door, garage entrance door, or rear entrance door. Can be single- or multi-panel and surface can be smooth or textured.
Swing in or out and are mostly used to access a patio, deck, or porch. Offer a tighter seal than sliding doors, keeping the weather out and your heated or cooled air in.
Door panels slide horizontally on a track to open and close. Because doors don’t need to swing, can be a space saver in homes where square footage is at a premium.
