what is a casement window

A casement window is a window hinged on one side that opens outward or inward like a door, usually with a crank or latch. It’s a common style for good ventilation and an unobstructed view.

Quick Scoop

• How it works: The sash is attached with side hinges and swings open.

• Main benefit: It can catch and direct airflow into a room, which makes it useful where ventilation matters.

• Common spots: Kitchens, bathrooms, and other areas where you want easy airflow.

Simple example

If you turn a crank and the window swings open from the side, that’s a casement window.

TL;DR

A casement window is a side-hinged window that opens like a door, often with a crank, and is valued for airflow and clear views.
