About the Marvin Clad Bay Window

The Marvin Clad Bay Window is made up of a series of smaller windows that are strategically fit together in order to create this beautiful bay window. Bay windows are an ideal centerpiece to your space. This window's desirable appearance can add valuable space to your room, open up your views to the outside, or even create a functional nook.

The Marvin Clad Bay Window is comprised of the superior extruded aluminum clad on the exterior, but on the interior, it is made up of solid wood.
