Casement and Awning Windows
Contemporary Style and outstanding performance.
Integrated crank with fold-away handle. This is no ordinary casement window crank.

The sleek, color-matched crank comes standard on all ThermaStar by Pella vinyl casement and awning windows. Exceptional performance. Durable lock strikes resist rust and corrosion and ensure years of dependable performance. Extra security. Dual sash locks on awning windows provide added protection. Casement windows provide a modern appearance with more light and view. They feature one hinged sash that swings out. A great choice for difficult to reach areas - like over the kitchen sink. Awning windows can be either traditional or contemporary when paired with other window types. Hinged at the top, they open out like an awning. They're often placed above or below other windows or over doors for more light and ventilation.
