See How Our Fiberglass is the Best Fiberglass for Your Project
When it comes to fiberglass windows, not all materials are created equal. At Pella Windows & Doors of Omaha and Lincoln, our proprietary fiberglass stands out from the competition. Engineered with strategically woven fibers for exceptional strength, stability, and weather resistance, Pella fiberglass outperforms the random fiber construction found in many other top window brands.
Fiberglass is STRONG. We made it the STRONGEST Material for Windows.
At Pella Windows & Doors of Omaha and Lincoln, we don’t just meet industry standards — we go beyond them, rigorously testing our fiberglass windows and doors to ensure they’re built to last through decades of Nebraska’s toughest weather. What sets us apart isn’t just our proprietary fiberglass, known for its unmatched strength and low-maintenance durability — it’s also our team of highly trained local installation experts who get the job done right the first time. The result? Fewer callbacks, greater peace of mind, and windows that perform beautifully for years to come.
Putting our fiberglass to the test
Pella Impervia Fiberglass vs. 6,000-Pound Truck
Pella Impervia fiberglass vs. 6,000-pound truck. That’s right. We suspended a 3-ton pickup from four window stile lineals and they stayed intact. See our fiberglass put to the test.
Pella Impervia Fiberglass vs. 1,000 Pounds of Concrete
Pella Impervia fiberglass vs. 1,000 pounds of concrete. We hung concrete slabs from a Pella Impervia patio door jamb lineal and guess what happened? It refused to give.
Pella Impervia Fiberglass vs. Bowling Ball
Pella Impervia fiberglass vs. bowling ball. Even a 10-pound bowling ball dropped from seven feet in the air wasn’t enough to destroy our fiberglass.
