The tripane glazing option from Marvin’s Integrity window and door series offers increased energy efficiency for the firm’s Wood-Ultrex line. Tripane windows combine Ultrex fiberglass with three panes of glass and argon gas to provide superior insulation, with a U-factor of 0.18 to 0.20. Standard sizes are available, as well as custom sizes in 1/64” increments. The windows are compatible with all of Integrity’s current design and hardware options.
