Awning window has a crank mechanism for opening, but rather than opening from the side, the awning window opens outward from the bottom or middle. That means that regardless of weather conditions, the awning window can be opened to improve ventilation. Rain will simply run off the pane, and won’t be able to seep in.
The crank mechanism keeps the window open at exactly the width you prefer. Awning windows may be a single pane or multiple panes, and can be combined with other window styles for characteristic effects. Many homeowners like to place awning windows along the top of a wall, where light and air are allowed in, without compromising the amount of wall space. .
