ENERGY-EFFICIENT, LOW-E WINDOWS
Our low-e windows can save quite a bit on your AC bills. Ask about our replacement window energy-efficient options and no-charge argon.
Whether you purchase vinyl, wood, composite or aluminum low-e windows, each comes in varying degrees of energy efficiency. It’s determined by the type of frame material, number of glass panes, gas insulation sandwiched between the layers of glass, and the number of low-e coatings on the glass. (Learn more here.)
Low-e windows can save quite a bit on air conditioning bills, thanks to their ability to reflect heat and keep it from entering a home.
It’s useful to know that low-e and energy efficiency are not exactly the same thing. Low-e glass adds to how energy efficient a window is through a low-emissive film that reflects heat, but not every energy efficient window includes low-e glass. Also, there are varying levels of energy efficiency and low-e window glass treatments, so it’s important to discuss your options before making a purchase, and review the energy efficiency rating of the window you are considering.

“DunRite was my third quote, after disappointing quotes from a local home improvement store and another installer. The rates they had quoted were bloated with unnecessary lifetime free replacement warranties and unimpressive or pushy salespeople.
From measuring and quote to leaving a quality job spotlessly cleaned up, this experience has been exactly as promised. Plus, the prices were fantastic! One window came defective from the manufacturer, but they handled it seamlessly and quickly. I highly recommend them.
They installed nine low-e windows, and a set of french doors with built-in mini-blinds and a pet door on my patio.”
Here’s What Our Customers Say…
The installers were efficient and cleaned everything up nicely. Our salesman, Sal, was awesome. He was very accommodating. He answered some questions for me about other windows and doors in my house. He offered my advice on some screen installation. He actually recommended a different type of company to complete the work I wanted done. (just like the movie Miracle on 34th Street). We were not happy with one of the choices we made with the door installation. We thought we would like our choice of framework but did not like the selection once it was up. Even though it was DunRite’s fault, they exchanged the section we were not happy with and did not charge us extra money for their time or the new materials.
I would highly recommend the company.
Are energy-efficient windows worth it? According to Energy Star®, a $412 monthly utility bill in the summer can drop to as little as $185 for a Phoenix resident – that’s a significant 51% drop!
Owner Sal Sucato suggests most homeowners may see a more modest decrease of 25-35% for their homes, depending on many variables.
Just remember, going from single-pane windows to double-pane aren’t enough for this kind of savings. High performance upgrades might be needed, such as low-e and gas insulation. We don’t recommend triple-pane windows, foam insulation upgrades, accidental glass breakage warranties or self-cleaning glass. Be sure to look at the performance ratings for your specific product!
How much can low-e window coatings help?
This is one of our most recommended upgrades. It helps the glass reflect heat so it doesn’t enter the home, retain heat when it’s cold outside, and block UV rays that can fade furniture, window coverings, paint, and artwork on the walls.
All window manufacturers use glass from the same sources in their product lines, but their proprietary low-e coatings layered on the glass can have incredible impact on the window’s energy efficiency. It makes a big difference. Most windows today come with two coatings (low-E2) as a standard feature, and many offer upgrades to three coatings (low-E3), which is definitely a worthy upgrade in Arizona. Ask us about it today!
Here’s a Video That Some Homeowners Find Useful…
What are a few other things to look for, when considering energy efficiency?
There are two types of labels that tell a homeowner the energy efficiency of a product. Since you probably won’t see product with the labels attached until the actual installation date, it’s not a bad idea to ask the salesperson, or take a moment to look them up on the manufacturer’s website. You can also ask how more energy efficient products will impact price and any specific product they may be recommending for your home. Sometimes low cost upgrades can add drastic energy savings you’ll like when the air conditioning bills arrive.
The most important label is from the NFRC (National Fenestration Rating Council). It includes several different performance measurements to consider:
- U-Factor, which measures heat escaping from the inside of a room. You are looking for a low number close to 0.20, which indicates zero heat loss.
- Solar Heat Gain Coefficient, which measures unwanted heat coming into a room. Rock bottom numbers ranging from 0.15 to 0.20 will save the most money on utility bills.
- Visible Transmittance, which measures how much natural light is let into the room. Higher numbers (up to 1.0) are better.
- Air leakage is pretty self-explanatory – who likes drafts? Less than 0.30 is good.
Some product also include an Energy Star label, which signifies it is a certified product that meets Energy Star criteria in their area of the country.
