Casement Windows & Sliding Windows
A casement window is hinged at the side and opens outward. It provides excellent ventilation at times literally reaching out and catching the breeze. It looks like a narrow picture window because, unlike double hung or sliding windows, it has no rail to obstruct the view.
Some casement windows are simply pushed open, but most have a hand crank. Screens are placed on the inside of the window, where they're more protected from the elements. If you're installing windows over a sink, countertop or appliance, a casement window with a crank can be the perfect solution.
