The Best Composite Windows: Why Infinity from Marvin® Is Leading the Pack
When it comes to replacing your windows, homeowners today have more choices than ever. But with so many brands and materials on the market, how do you know which window will truly stand the test of time?
If you’ve done any research lately—or even walked through a home show—you’ve probably heard the name Infinity from Marvin®. And if you haven’t, now’s the time to get familiar. In 2024, Infinity has been making serious waves in the remodeling and home improvement industry. Why? Because their proprietary fiberglass composite window system is outperforming traditional vinyl, wood, and even many composite windows on the market.
What Makes a Window “The Best?”
Energy efficiency? Of course. Durability? Absolutely. But the best windows today are about more than performance on paper. They offer:
-
Longevity in tough climates like Colorado’s
-
Aesthetic appeal that complements modern and traditional homes
-
Low maintenance so you can focus on living—not scraping, sealing, or repainting
-
Sustainable design that reduces waste and maximizes home value
Infinity from Marvin® checks every one of those boxes.
Not All Composite Windows Are Created Equal
The term composite gets thrown around a lot in the window industry. But not all composite windows are built the same—or perform the same. Some brands blend wood fibers with plastic. Others use reconstituted materials with fillers. Infinity, however, uses Ultrex® fiberglass—a pultruded fiberglass material so strong and stable that it’s often mistaken for metal.
This isn’t your average composite. It expands 87% less than vinyl and is 8x stronger. That means your windows stay square, sealed, and weather-tight—even in the face of hail, blazing sun, or frigid winters.
Why Infinity from Marvin® Is a Standout
Here’s why Infinity has taken the top spot among composite window brands this year:
-
Built with Ultrex® fiberglass – Engineered to outperform other materials in every category that matters: strength, thermal performance, and lifespan.
-
Slim, modern profiles – Get more glass and less frame for better views and more natural light.
-
Custom-fit replacement – Infinity windows are measured to fit your home exactly, reducing gaps and increasing energy efficiency.
-
Backed by Marvin – One of the most trusted names in windows for over 100 years.
