MI Windows and Doors has significantly improved the insulation and energy-efficiency of several replacement window products with the addition of krypton gas. A better insulator than the more commonly used argon, krypton-enhanced insulated glass is now available with MI’s 1650 double-hung, 1650 fixed, and 1685 double-slider triple-pane windows.
“MI Windows and Doors is dedicated to providing customers with the highest-performing products available in today’s marketplace,” says Josh Williard, MI’s director of products. “The introduction of krypton to our window lines is just another example of these value-added efforts.”
Denser than argon, krypton is more effective at blocking or decreasing the flow of heat in and out of homes. In window terms, it has a better U-value. A window’s U-value measures the rate of heat transfer; thus, the lower the U-value, the better. The gas is pumped between the panes of insulated glass, which are separated by MI’s thermally efficient, warm-edge spacer system. With krypton, the U-value on MI’s 1650 triple-pane, double-hung window is 0.17, compared to 0.21 with argon.
