Marvin Ulitmate Casement Windows

Ultimate Casement and Awning Windows from Marvin® are now the biggest wood-clad operating windows in the industry. This
family of windows delivers exceptional beauty, craftsmanship and design flexibility without sacrificing performance. In fact, the largest
Casement Window (36" x 102") achieves an industry-leading CW-PG40 rating. Functionality is taken to new heights thanks to
exclusive, adjustable hardware. Concealed multi-point locks improve fit and operation, and the casement’s wash mode allows the
window to be rotated to clean the exterior from inside the home. With a hinge bar that can carry up to 150 lbs of sash weight, even
the biggest windows open effortlessly. As with all Marvin products, unsurpassed attention to detail and stunning views come standard.
