Double-hung
Both sashes move vertically. On applicable models, tilt-in sashes make the outer glass easier to reach for cleaning.
How do you want it to open?
The right style starts with the room: the view, the airflow, and the space around the opening.
Single-hung
The lower sash opens and the upper sash stays fixed. Start with ValuePro when comparing this format.
Sliding
The sash moves sideways. Consider the direction of opening and how you will reach the screen.
Picture
Fixed glass frames the view. Pair it with an operating window when the room also needs ventilation.
Casement & awning
A casement is hinged at the side; an awning is hinged at the top. Leave room outside for the sash to open.
Bay & bow
Several windows form a projecting assembly. Include support, roofing and interior finishing in the project plan.
Style illustrations are diagrams, not product specifications. Available formats vary by Alside line and location.
Think about both sides of the wall.
A window should work from the sofa, at the kitchen sink, and outside near a walkway. Check opening clearance, cleaning access and the arrangement of nearby windows.
If a window serves a bedroom or another area with code requirements, have a qualified local professional confirm the required opening and glazing.
