Incredible Sized Windows With Commercial Performance: Marvin Meets Growing Need with the New Ultimate Double Hung Magnum

To provide a better solution for building professionals needing easy-to-operate, high-performing and historically-compliant double-hung windows in large sizes, Marvin Windows and Doors, the premier manufacturer of made-to-order wood and clad wood windows and doors, proudly introduces the Ultimate Double Hung Magnum.

"The Ultimate Double Hung Magnum is exciting because it's the first wood window to offer incredibly large sizes that perform to commercial standards," said Thomas Goetz, product planner for Marvin. "The Ultimate Double Hung Magnum now gives building professionals the opportunity to use large wood windows where they previously had to use an alternate material to meet performance requirements."

"As urban rebirth continues to drive the refurbishment of historic buildings and factories into lofts and business units, there's a growing demand for large double-hung windows that meet energy efficiency needs, historic compliance and tight planning budgets," said Goetz. "The new Ultimate Double Hung Magnum gives building professionals a window that will fit a wide range of performance and operation needs."

A high-quality, spiral balance system allows the Ultimate Double Hung Magnum to achieve easy, smooth operation.

The constant force of the spiral balance system, which meets AMMA 902-99 Class 5 specification, creates even pressure to provide minimal effort whether opening or closing the window. The spiral balance system will adjust up to 10 pounds for fine tuning and carries over 70 percent of the sash weight. Typical double-hung balance systems carry only 30 percent of the sash weight. Expected to be available in fall 2005, the Ultimate Double Hung Magnum has superior performance against air, water and structural infiltration.

The Ultimate Double Hung Magnum meets a commercial design pressure rating of H-C50 for window openings nearly five feet wide and nine feet tall, as certified by the Window & Door Manufactures Association (WDMA).

Larger sizes are available at a commercial design pressure rating of H-C30.

The Ultimate Double Hung Magnum achieves its traditional look through several design features including an interior stop system, which results in minimally exposed vinyl, weather-stripping and interior fasteners. Beautifully-designed shadow lines on the wood or clad exterior and a tall bottom rail provide further aesthetic appeal in creating a traditional, robust wood window appearance. In addition, the sightlines and profiles are consistent to Marvin's line of Ultimate Double Hung windows.

Designed to simplify installation and ensure top performance, the Ultimate Double Hung Magnum has pre-drilled installation holes, accessed through easily removable covers, to facilitate fastening through the jamb. A unique, patent-pending jamb carrier system provides fine horizontal adjustment every 12 inches along the jamb for optimal trim reveals and better performance. As part of the Ultimate Double Hung product line, the Ultimate Double Hung Magnum has numerous options to provide design flexibility including several wood species, divided lite choices, 19 select clad colors and glazing options such as low E II with argon gas.

The Ultimate Double Hung Magnum has a rich, warm, wood interior and a durable, extruded aluminum clad exterior for an unbeatable combination of strength and beauty. Marvin's extruded aluminum cladding resists chipping, chalking, and fading and has a commercial grade finish that exceeds the industry's highest, AAMA 2605-02, specification.

Additional options for the Ultimate Double Hung Magnum include extruded panning and casing accessories, custodial locks and sash limiters for added safety, and thick subsills for a more distinct, traditional look.
