NX-4000 Series Thermal Window Offers the Distinctive and Historic Look of a Hung Window with High Energy Efficiency

To maintain the historic look of a building while also providing high energy efficiency, we recently introduced the NX-4000 Series Thermal Window. By incorporating the benefits of the proven NX-3000 projected window series, the new NX-4000 Series Thermal Window offers the performance of a projecting window with the distinctive look of a hung window making it an ideal solution for many retrofit applications.

The energy-efficient window features the NexGen Thermal Barrier System™, NexGen Energy Spacer™ and 1-inch insulating glass. The NX-4000 offers outstanding air and water performance and was tested to a design pressure of 80 psf and water performance level of 15 psf.

Additionally, the NX-4000 Series Thermal Window provides increased durability, trouble-free operation and flexibility while maintaining the hung window aesthetic. For increased resilience, the window uses hollow extrusion profiles with Euro-groove construction for reliable hardware attachment, which are proven to be stronger than traditional mechanical fastener methods.

The ability to triple-glaze, using the combination of 1-inch insulating glass, access panel and internal blinds keeps things quieter, adds privacy and makes the NX-4000 Series Thermal Window ideal for schools and medical facilities. Designed with a master frame depth of 4-5/8 inches and a 3-1/8 inches operable vent depth, the projecting window has an exaggerated offset of 1-1/4 inch minimum between the upper and lower exterior glass surfaces. Bevel edge framing on the vents and fixed lites replicate the look of a putty glazed window while optional exterior profile muntin grids can simulate divided lites and offer several additional pleasing design options.
