U-Value & Winter Insulating Performance

Insulation performance is measured to determine how effectively a window keeps heat in a room during winter conditions. Insulation performance is measured by U-Value and the LOWER the U-Value the better the window performs. See NFRC chart to the right and see how effectively our glass options perform compared to Double Pane Clear insulated glass.

Note: New 25C Tax Credit for 2023- Only Gilkey Ultra Triple Pane (Energy Star Most Efficient) will qualify.

Windows facing East or West

The ultimate performance glass. It just might make all other low-E glass obsolete. It provides the highest levels of year-round comfort and energy savings, making it the perfect glass no matter where you live. The secret? An unprecedented triple layer of silver. This is beyond ordinary, setting a new standard.

Endur™

High Performance Coatings

LoÉ-i89®

Enhanced Performing Glass.
A special coating of indium on the indoor light reflects heat back into the room thus lowering U-Values for better winter time comfort.

LoÉ-180®

Ultra Clear Performance.
A single layer of silver LoE ideal for added insulation when used in conjunction with LoE3-366® or LoE2-270®. Allows for high visible light.

Neat+® Glass (Optional)

Windows coated with Neat+® harness the power of the sun’s UV rays to loosen dirt so water can rinse it away leaving windows virtually spotless.

As always from marketing team to installation was professional, courteous and caring. The installation was excellent and cleanup was thorough. The quality and the warranty of the product are excellent. I love my new door. I highly recommend Gilkey Window Co.

I worked with Tom S. as my representative and Brian C. as my installer. I couldn’t have been more pleased with both sides of the experience. I reside in a home that was built in 1876 and I needed full replacement of 3 outside doors & door frames, I was not looking forward to the process.Gilkey was my 3rd effort at having someone come look at it. Should’ve been my first. The way Tom would make sure he understood everything I wanted, to fielding my calls when I had another question and not hesitating to ask someone (Brian) if he didn’t have an answer, along with great follow up.Brian C. was quite a talent. It was so refreshing to have someone work on your home that paid that much attention to detail, commitment to a well done job as if their own and preserving the aesthetic of a home built in 1876, incredible. Well done, Brian. Well done.Tom S. & Brian C. knocked it out of the park for me with every aspect of the project, especially when it seems so hard to find anymore. Thank you, it was a pleasure working with you both and Gilkey.

Back in October of 2022 we had a representative come out to give a free estimate. The pitch was very quick and not overly long like a competitor (Renewal), he answered all of our questions, and the rep was able to email us a quote that same day. Granted, we had to do some haggling on our part to get as good of a discount as we could squeeze.Regardless, the rep said it would take 20 weeks before the sliding patio door could be installed. Fast forward 20 weeks later, we got an email that our door was done but it didn’t end up getting schedule to be installed for another two weeks. So the wasn’t exactly right on the date, but close enough.Really, there were really only two negatives, which was the day before installation we got a call saying it had to be postponed one day due to staff shortages and vehicle problems. Since I work from home, it wasn’t a big deal. The other negative was on the day of installation the screen door was ready and we had to wait another week before that got installed. While I would have given one less star for that, Gilkey compensated us by upgrading the screen to the higher durable pet screen for free.John, who installed the door by himself, did a fantastic job from what we could tell. No issues as of yet. And Jason who installed the screen door did so very quickly.
