Perfect Window Glass for Texas Weather

Replacement Windows Made in Texas, by Texans, for Texas Weather

NT Window products are manufactured in Fort Worth, Texas.

Made by Texans and built specifically for the tough Texas summer heat and winter cold, our Low-E 366 is the perfect glass for Texas.

In the summer, when the temperature soars, regular single-pane or double-pane glass can’t handle the heat. Standard tinted glass does little to reduce heat and spoils the view. Our patented Cardinal Low-E 366 glass has been specially made to block the Texas heat without blocking the view. It lets more light in and keeps the heat out. Your home stays comfortable all summer with dramatically lower utility bills.

Additionally, our patented glass provides exceptional fading protection for your carpet, furniture, and window coverings, keeping them beautiful for years to come. It blocks 95% of the sun’s damaging rays that lead to fading in your home. No more fading or discoloration.

During the cold winter, the insulating qualities of your windows directly affect the comfort of the room. With over 75% of the window surface made of glass, better-insulated glass directly affects the warmth in your rooms.

Choose our Cardinal Low-E 366 glass with argon gas for maximum energy efficiency. It’s the perfect window glass for Texas weather.

With three layers of silver coating that block solar gain, reflect heat, and let light stream in, combined with argon gas that resists heat, cold, and sound transfer, you have the perfect combination of high-performance features to keep your home comfortable and energy efficient year-round.

Southern Living Cardinal Low-E 366 glass with argon gas is the Texas glass choice for all seasons.
