Marvin All Ultrex Casement Windows
Marvin's All Ultrex casement windows are available in custom sizes of 1/64" increments. The windows are made with Ultrex, a fiberglass product that's eight times as strong as vinyl. The windows have folding handles and use a single-handle multi-point sequential locking system for security. All Ultrex casement windows come with the option of ultra energy efficient LoE3-366 glass, which delivers a U-value and solar heat gain coefficient equal to or less than 0.30, thus qualifying for the energy efficiency tax credit.
