The 5-Series Double Hung Re-Engineered

Apr 30, 2019 | Behind the Blinds, What's New

The 5-Series is now EnergyStar v6.0 Northern Compliant

We’ve refined the design of our 5-Series double hung window to better meet the customer need for a value-based window solution, without sacrificing quality and performance. Read more about all product changes here.

Please note that all orders received through April 30th will be built to original 5 series double hung design. Orders received after close of business on April 30, and thereafter will be built with the new 5-Series double hung design. We will not have the opportunity to revert back to the original design after the switch is made.
