Perfectly symmetrical to our casement and awning windows, the fixed casement allows you to mull large fixed windows to casement or awnings while maintaining the same look and sight lines. The low profile picture window features clean, simple lines that pair perfectly with contemporary design.

I installed my first Enerlux windows in my upstairs bedrooms back in August of 2018. I was so impressed by the quality of build and increased comfort in those rooms, that I made the decision to replace the rest of the windows in my house, a total of 20 window openings. I was informed of their new patio door design, so I also had them order two new patio doors.

It was a great choice! My house is so quiet now, triple pane windows really make a difference. Every month I receive a performance report from my Lennox thermostat, the numbers speak for themselves. Here is my 2020 and 2021 November and December statistics: November 2020 heating time was 169 hours, fan usage was 155 hours November 2021 heating time was 145 hours, fan usage was 52 hours November 2020 average OUTSIDE temp was 43 degrees, average INSIDE temp was 69 degrees. November 2021 average OUTSIDE temp was 35 degrees, average INSIDE temp was 69 degrees.

So 2020 outside temps were WARMER than 2021, yet, our 2021 usage is well below 2020 with the thermostat set at exactly the same settings. December 2020 heating time was 294 hours, fan usage was 274 hours December 2021 heating time was 217 hours, fan usage was 143 hours December 2020 average OUTSIDE temp was 28 degrees, average INSIDE temp was same as November at 69 degrees.

In the past years, it was too expensive to raise the thermostat to compensate for the drafty windows. In December 2021, the average outside temp was EXACTLY the same as 2020, BUT this December I modified the heating schedule so it raises the house temps to a comfortable 72 degrees from 4pm-10pm, then it drops to a cooler temp while we are sleeping, so it now reflects a HIGHER average INSIDE temp of 70 degrees.

So even WITH the warmer inside temp settings, we are using less heat hours and fan usage in 2021 than we did in 2020. It's really nice to sit in my chair next to the big picture windows when we had 30mph north winds the other day and temps hovering around zero outside. I was VERY comfortable, no drafts and NO CONDENSATION ON ANY WINDOW IN THE ENTIRE HOUSE! NOT ONE, even in our bathrooms. Pretty impressive! Thanks for making such a great product! PS The Flex Screen screens that my windows came with are literally the best design ever! Worth every penny!

We have done many house projects over the past 20-30 years, including replacing most of the windows in our house. We always try to use the highest quality products whenever possible, especially with windows as cutting corners will cost far more in the long run. A recent project involved finishing off attic space and expanding the main bedroom/closet and adding a new window.

Someone recommended Enerlux and it was a great decision to use their window! It was a custom window with opaque glass that needed to closely match existing windows on the front of the house. The window was fabulous quality, fit perfectly, and far exceeded our expectations. This north facing window is 100% airtight and simply a great product. Mark and Mitch were really easy to work with and highly responsive. I will absolutely recommend their windows to anyone looking for a high quality and reasonably priced product.

Enerlux. great company, great service, great product. The back door of my home needed to be replaced. The frame consisted of two fixed panels and a door in the middle. I priced sliding glass doors at several companies and was shocked at the high price for the low quality. I checked online and found a company named Enerlux. I called (expecting to leave a message) and spoke with Mark Houlton.

We spoke at length and I explained the condition of my existing door and what I was looking to replace it with. My husband and I decided to visit Enerlux in Nebraska where we met Mark and a number of the other staff. We were shown samples of what our door would look like, including rollers, hardware, glass. Pleased with our meeting, we placed an order.

I called on several occasions to check on the progress of the door and Mark was always patient and answered my questions. After completion, there were some complications on finding a freight company to make the delivery, so Mark got a company truck and had his son drive the door to Tulsa. Both the installer and his assistant were amazed at the craftsmanship and the quality of the door.

They were also impressed with the written installation instructions. I was asked to have the installer call Enerlux before starting the project, so they could offer further installation instructions and answer any concerns they may have. The installer was once again impressed with Enerlux's attention to details. The door is made of fiberglass (which is what I wanted), and it runs exceptionally smooth and although it's a solidly built door, it doesn't weigh a ton.

We live next to a busy road and this door helps cut out most of the traffic noise, not to mention it's a well sealed, well insulated door. I couldn't be more satisfied with this purchase. THANK YOU, MARK AND ENERLUX for producing a superb product and for your outstanding customer service.

Best quality, price and most efficient windows made in the USA, with the strength of fiberglass, high density foam insulated frames and sashes, all based off of Canadian efficiency.

Every time I install an Enerlux Window I'm reminded of the superior quality and craftsmanship. Just replace another Milgard contractor grade vinyl double pane with a TRIPLE pane fiberglass ENERLUX awaning. The heft of the window alone tells you volumes about the quality. Performance is unmatched by any other the brand name window manufacturers. ENERLUX is the only name you should look for in both new construction and remodeling. EXCELLENT quality at a very competitive price point.

We just installed 22 Enerlux windows in our old Farmhouse and love them! Hugh improvment over doublehung windows. Super high quality casement window that match perfectly with our old house. I researched a lot of windows before deciding on Enerlux. I believe Enerlux they are the best casement windows on the market! Thank you for a quality product!

Best windows and doors on the market! No measurement is "custom" for Enerlux, they make every window and door to fit your opening. The closed cell insulated heavy duty fiberglass frames are stronger than you can imagine and the German hardware is top notch. They even made me a four panel bi-parting sliding door that was 24' wide, with four 6' wide x 8' high windows.

They are beautiful! Custom tinted glass for specific compass orientations, interior and exterior different colored painted applications, they can do it all and for an exceptional price point. Talk to Thad Sears, he's an exceptional sales representative for Enerlux.

I have gotten half a dozen windows from Enerlux over the past couple of years. This past winter is the warmest I've been in this house in my life. The windows are great and the service and support are wonderful. Would not buy any other windows!

I'm from Boston and was looking for energy efficient fiberglass windows. I looked at all the standards Marvin, Pella, Anderson and also Inline and Fibertec from Canada. I happened to stumble on an article about EnerLux and decided to give them a call. After much research their product on paper is superior to anything sold in this country and had the same energy numbers as the Canadian windows (much stricter energy standards than US) plus much better hardware (not plastic).

I ended up getting triple pane casements and could not be happier. They are beautiful windows and well crafted. They open more smoothly than any of the Marvin, Pella or Anderson I tried. Thad, the rep I dealt with at the company knows his product inside and out. We only had only 1 small issue in the order, not related to the quality of the product, and he addressed it and was responsive the entire time.

You can buy these windows knowing that you're buying the best fiberglass window from a company who stands not only behind their product but their customer service. Thanks Thad!

We have just purchased Enerlux Windows. We went by where they make them in Nebraska. Very large facility. Really enjoyed watching the process and our contractor LOVED the quality of the window. They can make them any size you want and have the structure and stability we love. They are a heavy well built window. We purchased the fiberglass. We are retiring soon and want a solid, well built home that will last for generations.

I am extremely impressed by Enerlux's high quality craftsmanship and attention to detail. Their integrity has shown through in all aspects of our work together. I will definitely be contacting them again when I replace the rest of my windows.

After extensive research, EnerLux was the only company I found that provided a passive solar window with a good U value at a fair price.

Just an update to tell you that the other day my wife said whatever I paid for the shower window, it was well worth it. Thanks again.
