EnerCore™

EnerCore™ is a revolutionary breakthrough in window technology. 

Unlike foam filled window sashes, EnerCore is a thermally bonded, structured insulation system.

Included in all of our Double Hung and Slider window sashes, EnerCore is designed to offer superior thermal performance, accommodate triple glazing, and reduce air filtration.

These features, combined with Jantek's EnergyMiser Technology, provide greater energy savings.
