NT Windows

NT Window is a leading window manufacturer of aluminum and vinyl windows, both serving the replacement and new construction markets. NT Window Inc. was created over 25 years ago when two existing window manufacturers with excellent reputations in their fields – merged. NT Window offers a complete line conforming to the needs of residential and commercial window markets.

With an in-house extrusion supplier and over 250 independent dealer and distributor relationships in the southern United States including Texas, Oklahoma, Louisiana, Arkansas, New Mexico, and Mississippi, NT Window produces over 100,000 windows per year in their Dallas/Fort Worth manufacturing plant.

NT Window offers a complete line of low maintenance vinyl windows in a variety of styles and color options to fit any home from traditional to contemporary.

Most windows offered by NT are energy-efficient and come with a lifetime warranty that requires no registration and is transferable to a new owner if the house sells. All of their window lines are NFRC and AAMA certified to meet your specific bulding requirements.
