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
