Enerlux Windows & Doors has been producing quality products since 2008. They’re a family-owned business operating out of Crete, Nebraska, and they’re known for durable fiberglass door and window solutions engineered for top-notch energy efficiency.
They offer various customization options with their products, as a larger company would, but pride themselves on small-town friendliness and a collaborative approach with each customer. Their windows and doors are low-maintenance, aesthetically pleasing, and competitively priced compared to the larger industry players.
Why fiberglass is king
Fiberglass is the only type of window and door they produce. The team develops fiberglass products, as years of real-world testing have reported that it is the strongest and most energy-efficient material for windows and doors. Home buyers are increasingly opting for quality home features over anything else, and Enerlux products pass the test.

Fiberglass is 500 times less conductive than aluminum and 8 times stronger than vinyl, making it a safer and more durable material than both. Customers who opt for fiberglass also never have to worry about the material rotting, and fiberglass also meets today’s modern design standards.
Most importantly, fiberglass is highly energy-efficient. Enerlux fiberglass products, in particular, have a high R-value. R-value, short for “resistance value,” is a measure of thermal resistance based on the properties and thickness of a material. A high R-value for Enerlux means their windows and doors are excellent at keeping heat from moving in or out, allowing customers to save on energy bills. Enerlux boasts a 7.7 R-value, whereas many competitors fall in the 4.3-4.5 range.
The Enerlux difference
Yes, many companies offer fiberglass products. However, not all products are produced with the same quality and care. Enerlux uses a triple-panning, triple-weather-stripping technique that helps them achieve more sustainability while eliminating water and air infiltration.

Their glass is also solar-tuned, meaning it reduces solar heat gain, allowing homeowners to use less AC and keep more money in their pockets from their energy bills. In addition to quality glass, Enerlux chemically fuses their edges and corners into their frames, whereas other businesses typically go with an old-school screw method. It’s precision and care, met with the latest and greatest in production techniques.
