Energy Star

NT Window is proud to be a ENERGY STAR® Partner offering our customers windows and doors that are designed to save energy and make their everyday living more comfortable. The ENERGY STAR® program certifies many products including windows, doors and skylights to ensure that they help protect the environment while keeping your energy costs low.

What is ENERGY STAR®?

In order for a product to earn the ENERGY STAR® label, the product undergoes a series of evaluations to determine how well energy is saved. The ENERGY STAR® program also evaluates how well products prevent greenhouse gases from being emitted into the atmosphere in order to keep our environment cleaner and air quality higher.

The U.S. Environmental Protection Agency has set strict guidelines for the ENERGY STAR® program to ensure that all products carrying this label meet the highest standards of efficiency. With energy costs and issues related to global warming top-of-mind for consumers, NT Window is committed to offering solutions that help consumers conserve energy and improve the quality of our environment.

Choosing ENERGY STAR® products over products that do not carry the label can save a household nearly $600 on energy bills each year. This is a substantial savings when you consider that the average household spends approximately $1,900 each year just on energy alone. When you choose NT Windows and doors that are ENERGY STAR® qualified, you’ll feel the comfort of saving energy every day.


ENERGY STAR® Most Efficient – Taking Savings to a Whole New Level.

Tax Credits

While the Bipartisan Budget Agreement (BBA) of 2018 did renew/extend tax credits for certain residential energy efficiency improvements, it specifically EXCLUDES any tax credit for windows, doors & skylights. The tax credit is available for calendar years 2014 – 2016. We have attached our Manufacturer Certification Statement below for use and reference as needed.
