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.
Check out the Product Specifications and watch our demonstration video on this page to learn more about our EnergyMiser Double Hung windows. Feel free to stop by our Medford, NJ Factory and Showroom, Monday through Friday - 9:00am to 5:00pm.
