EnergyMiser™ Double Hung Window

Interior view of double hung replacement window. Our most popular window, a Double Hung window is defined as having a horizontal meeting/lockrail and two operable sashes that can be raised or lowered, independent of one another, for ventilation. Because the sashes tilt-in for easy cleaning, Jantek’s Double Hung windows are a good choice in multi-level homes.

Jantek EnergyMiser Double Hung windows come standard with our proprietary  EnergyMiser Technology, including EnerCore sashes, which yields a R6 Insulation Value and a .18 U-Factor.
