How does it work for you?

Why Newtec Energy Star AffiliationsNewtec is a participant in the National Fenestration Rating Council’s Certification Program- a uniform national rating system for energy performance of fenestration products. Newtec Window and Door products are NFRC tested, certified and labeled.
Newtec offers unparalleled options that include reflective Low-E glass coatings, tinted glass coatings, air filled dual insulated glass assembly, Argon gas filled dual glass assembly, laminated glass, and full array of window trim accessories to ensure sealed system quality, and measurable long term energy efficiency.

Our Low-E glass is applied two, three or more layers of microscopic coatings filtering infrared and ultraviolet radiant solar energy while allowing visible light to pass through. This will make your rooms cooler in summer time, while in winter, Low-E glass will reflect heat back into your rooms while letting warm solar rays in, thus helping to keep your home warmer.

Our warm-edge, insulating glass sealant systems flex with the glass in hot or cold temperatures to help prevent sealant failure. These insulating spacer systems keep the edges of the glass warmer, dramatically reducing condensation while keeping warm air in and cold air out. Insulating gases, such as argon or krypton, are used in our double pane window and door products.

What Our Customers Are Saying

Don’t just take it from us, let our customers do the talking!

“My husband and I purchased a Chicago Bungalow in 2015 and discovered that the house was extremely inefficient. We had bad winter drafts and huge energy bills compared to our neighbors. We consulted with Newtec and they were able to create and custom solutions for our home at an amazing price.

I want to thank Magda for all her in office support and Boston for being so helpful in getting the windows to us. Thanks guys. “

“Our energy consumption statistics were 75% more than our neighborhoods. After looking at our heat and cool loss we realized very quickly we needed replacement windows. After pricing the markets we found Newtec.

After replacing our windows with Newtec we are saving more on our energy costs and are saving 50% now – Thanks Newtec. “

“I’m so grateful for the reduction in my energy bill. After consulting with New Tec and Magda I learned that my currently bungalow home had really inefficient windows which was driving up our energy costs. I looked at the various technologies and learned that I was willing to pay a little more now to save a lot in the long run. We purchased double hung and a bay bow windows from Newtec and are extremely satisfied.”
