Marvin Windows and Doors is ofering an innovative option for energy efficient windows: Tripane with Krypton*. Using proven tripane construction along with the superior insulating properties of Krypton gas, Marvin's new window option performs to our highest standards ever. "This remarkable window is an example of taking something that was already great and making it better," said Seth Stohs, regulatory product planner for Marvin Windows and Doors. Marvin has more than 800 glazing options certified by the National Fenestration Research Council (NFRC) as performing to a U-factor of 0.20 or lower. The U-factor measures heat loss through a window; the lower the number, the better. Many of Marvin's windows feature a U-factor that's at least 33% or stronger than the federal government's stringent ENERGY STAR standard. "We've taken ENERGY STAR standards and exceeded them by far," Stohs said.
Tripane with Krypton is available with a range of low-emissivity coatings suited to specific climate zones. It is ENERGY STAR rated and certified by the NFRC. Tripane with Krypton is designed for passive building and meets many energy and regulatory standards and codes.
* "Tripane with Krypton" refers to a blend of Krypton (primary gas), Argon and air. NFRC ratings are based on specifications, as shown in the NFRC database as AR3/Air, which are used to describe multiple gas content designs.
