EnergyMiser™ Slider Window

Slider windows with fixed center picture window Slider Windows are perfect for openings where a vertical sash meeting rail is preferred over a horizontal meeting rail (as in a double hung window) or, in an opening where the width is considerably greater than the height of the window. Slider windows are a good solution for hard-to-reach places, like above a kitchen sink. The clean lines and optimal glass surface lets in lots of light and they can be easily opened for ventilation.

We manufacture both two and three-lite models. Both sashes are operational on the two-lite model. The three-lite model (as seen in the image) has a fixed center lite and you can choose either one-half or one-third widths for the side lites. The operational sashes can be fully removed from the frames on both models for cleaning.

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