WHY ROSWELL HOMEOWNERS TRUST INFINITY BY MARVIN® WINDOWS

Residents of North Georgia know that the weather can be quite unpredictable, and they need windows that withstand high humidity and frequent temperature swings. Infinity windows deliver performance that stands up to real-world conditions. Our top-quality windows are designed to withstand high humidity and temperature swings throughout the year, helping to maintain consistent indoor comfort while improving energy efficiency. Many Roswell homeowners come to us after dealing with various window issues, including some with failing builder-grade vinyl windows. Infinity's Ultrex® fiberglass provides the strength and insulation needed to protect your investment with timeless style that fits any Roswell neighborhood.

Infinity by Marvin fiberglass windows are built with materials that prevent warping, corrosion, and condensation, improving comfort and energy efficiency in the entire home. Unlike traditional window materials, Ultrex fiberglass remains stable as temperatures change and does not absorb moisture, ensuring long-term durability and consistent performance. Combined with multi-pane glass, precision sealing, and durable weatherstripping, Infinity windows enhance curb appeal, preserve architectural character, and deliver reliable performance in any weather.

LASTING WINDOW PERFORMANCE

In the past, NG Windows carried more than 25 different window models for Roswell homeowners. Today, we only offer one: Infinity by Marvin fiberglass windows. Why? Because we believe they are by far the best. Infinity's patented Ultrex fiberglass delivers exceptional performance.
  • Expands 87% less than vinyl and resists contraction in any climate
  • Eight times stronger than vinyl
  • Ultrex fiberglass expands at virtually the same rate as glass, so the windows stay tight and true. This makes Infinity windows resistant to leaks, seal failures, and stress cracks, all of which can affect your home's energy efficiency
  • The look of traditional wood windows with less maintenance
