Window Series

1000 Series

North Star's most popular window, the 1000 Series has traditional look with a 3-1/4″ deep frame that is well suited for most applications. Energy efficient and durable, this window is available in a casement, awning, single-hung, double-hung, single-slider, double-slider and custom shape.

4000/5000 Series

Available in two frame depths – 4-1/2″ (4000 Series) and 5-1/4″ (5000 Series) – this full frame window positions the insulated glass unit on the warm side of the building envelope (the interior wall of your home), for reduced condensation and greater comfort. Available in a casement, awning, single-hung, and single-slider.

4000/5000 Hybrid Series

Architecturally inspired, our Hybrid Series window has the same features as the vinyl 4000/5000 series, but offers the benefits of an aluminum exterior in one innovative window system. This durable design unites the clean lines of an aluminum exterior with the easy maintenance and energy efficiency of a vinyl interior.
