Marvin’s Ultimate Casement merges revolutionary engineering with timeless design. A recessed sash offers design flexibility for new construction or full frame replacement. Durable hardware and multi-point locking systems allow for smooth operation even at the largest sizes – up to 40” x 96 1/8” or 36” x 102”. Convenient wash mode allows for the window to be turned so the exterior glass can be accessed and cleaned from the interior. The retractable screen can be easily opened and when closed integrates into the jamb. This creates a seamless look and eliminates the need for bulky and hard to use screens.
