The 5-Series Double Hung Window Re-Engineered
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.
