      Product Features

      The innovative NX-4000 Series Thermal Window is designed to offer the distinctive style of a hung replica window and high energy efficiency. The NX-4000 Series Thermal Window incorporates the benefits of Traco’s proven NX-3000 projected window with the added aesthetics needed for specialized retrofit projects, especially those requiring a historic appearance.

      NX-4000 Series Thermal Windows feature Traco’s NexGen ThermalBarrier System™, NexGen Energy Spacer™ and 1" insulating glass, making it one of the most energy-efficient glass and frame insulating products on the market today. Outstanding air and water performance is built into the NX-4000 Series along with the durability to keep it performing year after year. Since it is made from aluminum, this thermal frame window will never rot, warp or buckle due to moisture and weather exposure. And the ability to create a true single- or double-hung appearance with high thermal performance makes the NX-4000 Series the ideal solution for many retrofit applications.
