Next Generation Ultimate Double Hung Window

Marvin’s Next Generation Ultimate Double Hung Window is a classic reinvented. With its innovative keeperless hardware system, multi-point locking system, lockable vent mode and other performance and aesthetic-enhancing improvements, this window seamlessly combines state-of-the-art technology with Marvin’s legendary craftsmanship without sacrificing the traditional double-hung look.

Exclusive Features

  • Keeperless Hardware System: Another industry first. We’ve eliminated the upper-sash keeper in favor of a more modern, streamlined system that controls all aspects of the window’s operation.
  • Auto-Locking System: The first system of its kind that automatically locks when the window is closed. An audible “click” tells you the window is locked. You’ll never again forget to lock the windows.
  • Multi-point Locking System: This revolutionary multi-point system locks directly into the jambs of the window.
  • Vent Mode: This feature, which you will only find on the Next Generation Ultimate Double Hung, allows you to lock the window with four inches of clearance.

Unique Design Features

  • Aluminum Inter-lock: Eliminates drafts and improves the windows overall structural integrity.
  • Narrow Checkrail: A 1 15/16” checkrail provides a traditional look.
  • Independent Sash Operation: Because each sash operates independently, either can be locked while the other is open; a feature unique to Marvin.
  • Complete Wood Interior: For enhanced aesthetics, The Next Generation Ultimate Double Hung features a full wood interior, even in the jambs of the window.
  • Shorter Sill Liner: A minimal sill liner achieves a traditional design aesthetic, while the 14-degree sill bevel offers optimal water management and supports long-term durability.
  • Ease of Operation: Improved balance systems make the sash operate smoothly at all sizes.
