Your Trusted Marvin Window Dealer in Raleigh, NC
At Raleigh Windows & Siding, we’re proud to be a certified Marvin window dealer, offering Infinity from Marvin windows that combine style, strength, and long-term performance. These windows are known for their deep, rich wood-like grains and crisp, clean design — making them a beautiful upgrade for homes throughout Raleigh and the Triangle area.
The patented acrylic finish on Infinity windows is up to three times thicker than competitors’ finishes, offering superior protection against discoloration, scratches, and dents. And unlike many vinyl windows in Raleigh, which often have rough, welded corners, Infinity windows feature tight, mechanically bonded corners and slim frames to maximize your view.
These windows also look very crisp. It is not uncommon for vinyl windows around Raleigh NC to have messy welded corners. Infinity windows are tight and clean, with mechanically-bonded corners and narrow frames to maximize your view.

When you choose Infinity from Marvin, you’re investing in windows made with Ultrex fiberglass — a material that’s 8x stronger than vinyl and resists expanding or contracting during temperature changes. This durability means a snug fit that won’t warp or leak over time like vinyl.
Because these windows are so reliable, they come with a Lifetime Warranty from Marvin — a trusted name in windows with over 100 years of experience. As your local Marvin window dealer, we stand behind every installation.
Marvin Ultrex Fiberglass Windows: Superior Strength and Stability
At Raleigh Windows and Siding, we proudly offer Infinity by Marvin windows, featuring Ultrex—the most durable window frame material in the industry. As an authorized Marvin dealer in North Carolina, we provide exclusive access to these high-performance fiberglass windows. Ultrex is 8 times stronger than vinyl and resists expanding and contracting in any climate, ensuring a tight, snug fit that lasts for decades—perfect for Raleigh’s weather conditions.
Ultrex vs. Vinyl Windows
Vinyl windows can warp and shift under everyday Raleigh weather conditions — which may make them harder to open and close and reduce long-term performance. In contrast, Ultrex fiberglass, used in Infinity from Marvin windows, resists sticking, swelling, and warping. That means your windows and doors will continue to operate smoothly, year after year.
Ultrex vs. Wood Windows
Wood windows offer timeless beauty, but they often require frequent upkeep depending on the climate. Infinity from Marvin windows capture the rich details and profiles of traditional wood, without the ongoing maintenance. It’s the best of both worlds, delivered by your trusted Marvin window dealer in Raleigh.
