Window Styles

Casement Windows

Casement windows swing open on a side hinge with a crank, so the whole opening catches the breeze. They seal tighter than almost any other style, which makes them a favorite for hot East Bay summers and noisy streets.

How They Work

A Window That Opens Like a Door

A casement window is hinged on one side and opens outward with a crank or a push handle. Because the whole sash swings clear, you get airflow through the full opening instead of half of it, and the sash can catch a passing breeze and steer it into the room.

When it closes, the sash presses against the weatherstripping all the way around, like a door against its frame. That compression seal is why casements rank among the most energy-efficient and quietest operating windows you can buy.

Common Questions

Casement Window FAQ

Straight answers from the people who install them.

Generally, yes. When a casement closes, the sash presses into the weatherstripping all the way around, which seals tighter than the sliding seals on a slider.
Often, yes. We check the opening size and what’s outside the window, since a casement needs room to swing open, and confirm it works before ordering.
They’re one of the easiest ways to meet egress because the whole sash opens. We size them to the code for your bedroom.
Yes. The lock pulls the sash tight into the frame, and the hinge side is inside the window when closed, so there’s little to pry at.
It depends on the brand, material, size, glass and how many you’re replacing. We don’t quote a number before measuring. You get a fair, detailed written quote for free, and the quote is what you pay.
