Tripane with Krypton
Using tripane construction combined with the enhanced insulating properties of Krypton gas, Marvin’s triple-insulated window option meets many energy and regulatory standards and codes. Tripane with Krypton is available with a range of low-emissivity coatings suited to specific climate zones. It is also ENERGY STAR rated and certified by the National Fenestration Research Council. The windows can achieve a U-factor of .20 or lower, which is over 30% stronger than ENERGY STAR standards.
