Pella® Lifestyle Series Wood Casement Window

Mulled

Pella Lifestyle Series mulled casement windows include two casement windows of the same size. Mulling means that the two windows are attached together, creating a beautiful window opening larger than a single unit. Both casement windows open and close with the simple turn of a crank, making them especially convenient in tough-to-reach places. Personalize the look of your windows with grilles, finishes, hardware and more to create a style you love. These wood windows are built for everyday life and available with upgraded performance packages to make your home quieter and more comfortable.

Two wood casement windows joined together by their frames in the factory.
#1 performing wood window for the combination of energy, sound and value¹⁶
Available with built-in blinds, integrated shades, retractable screen and security sensors.
