The Ultimate Casement: The Most Innovative Window Just Got Better


The most innovative window on the market is now available for every home application. Marvin Windows and Doors introduces the Ultimate Casement for use in any application – new construction, remodeling or replacement projects.

  • The Ultimate Casement features a design exclusive: the revolutionary wash mode. In three simple steps, homeowners can rotate the exterior glass to the interior to wash it:
    • Crank handle twice.
    • Push down on the hardware arm and push the window away. Then crank the handle back.
    • Swing window all the way open, pulling it across towards the lock for accessibility to exterior glass.
  • With the wash mode, there is no need for ladders or scaffolding to keep windows clean.  And since the Ultimate Casement can be washed entirely from the interior, there is no risk of falling from upper floors.
  • In addition to the Ultimate Casement, Marvin Windows and Doors will offer the Ultimate Awning and an Ultimate Picture Window. Each window has matching profiles to seamlessly blend together in various configurations.
  • When the look of a double hung is preferred, but casement windows are needed for egress purposes, or because homeowners prefer the performance of a casement, the Ultimate Casement can be designed with a simulated check rail and a wide bottom rail  to mimic the look of a double hung.
  • The Ultimate Casement’s largest size is 40″ wide x 92″ tall or 36″ wide x 96″ tall and the awning window can reach a maximum size of 6′ x 6′.
  • The Ultimate Casement offers superior performance with a Design Pressure (DP) rating of 50. The commercial-grade hardware, the most durable on the market today, allows the window to operate smoothly while supporting a sash weight of up to 150 lbs.
  • Unlike other casement windows, which can take up to 14 cranks to open, the Ultimate Casement opens in only nine cranks.
  • The Ultimate Casement meets egress even at smaller sizes and is perfect for homeowners looking to expand their view. Opening close to the jamb, the Ultimate Casement lets in the maximum amount of fresh air and gives unobstructed views.
  • Installation of the Ultimate Casement is easy. Removable interior covers and pre-drilled jamb holes provide a clean, finished appearance. Adjustable hinges allow for fine-tuned installation and provide a snug fit over time.
  • To complete the exterior look of the Ultimate Casement, Marvin’s extruded aluminum cladding with a Kynar 500® finish is available in 19 colors and nine casings.
  • The Ultimate Casement helps improve a home’s energy efficiency with low E II insulating glass with argon to keep heat inside in the winter and out in the summer, lowering heating and cooling bills.


“We’ve seen how successful our Ultimate Replacement Casement has been and we are thrilled to offer the Ultimate Casement for expanded uses of this highly innovative window.  A new home or an addition will be greatly enhanced by the Ultimate Casement’s strength and beauty, as well as its convenient wash mode.”
