Pop out window

Marvin's Skycove is a new fully assembled pop-out glass unit that creates additional indoor space and gives homeowners more access to light. The company says Skycove is suitable for a wide range of projects and is the first pop-out window of its kind available in the U.S. Made from glass and steel, the unit features vertical framing that measures less than 3 inches, creating a seamless connection to the outdoors and offering more light than traditional openings. The unit has an integrated bench with 16 to 20 square feet of usable space, an aluminum interior and high-density fiberglass exterior, bottom insulation, and dual-pane or optional triple-pane glass.
