What Is Infinity’s Ultrex from Marvin Replacement Windows?

No other window material matches the strength and durability of Ultrex, a pultruded fiberglass material designed to outperform and outlast the competition. Marvin pioneered the patented Ultrex fiberglass-making process, which has been perfected over the last 30 years.

Graphic explaining why Ultrex is the perfect window material.

It begins by saturating strong glass cables in compounded resins. Then, the cables are pulled through a heated die and cut to size with a diamond-edged blade. Every step in the Ultrex production process plays a role in the material’s impressive performance.

Benefits of Infinity from Marvin Ultrex Fiberglass Windows

Could Infinity from Marvin windows be right for your home? They’re a major contender if you want to enjoy these benefits of Ultrex fiberglass:

  • Low maintenance: Because Ultrex fiberglass naturally withstands cracking, rotting, peeling, and corrosion, it requires little to no maintenance. Infinity from Marvin windows also feature a mechanically bonded inline acrylic finish, which is up to three times thicker than competitive window finishes. This provides superior resistance to discoloring, scratching, and denting for a long-lasting finish that never needs maintenance.
  • Beauty: The intricate profiles of Infinity from Marvin windows are designed to look and feel like traditional wood. You can even stain them to match the existing woodwork in your home! Since nothing matches the warmth of wood windows, you’ll be pleased with how Ultrex fiberglass replicates this look without needing to be sanded, repainted, or re-stained over the years.
  • Strength & durability: Ultrex is as strong as low carbon steel and eight times stronger than vinyl. It’s so tough that a diamond-edged blade is needed to cut it to size. Superior strength allows for a narrower window frame profile and more glass area, providing a wider view of the exterior. It also means Infinity from Marvin windows can withstand temperature changes, direct sunlight, and even harsh coastal conditions for a 38% longer life expectancy than vinyl windows.
  • Energy efficiency: One of the biggest reasons people replace their windows is to save energy. Combined with high-performance glass, Infinity from Marvin windows easily exceed ENERGY STAR® qualifications. The result is a home that’s easier to heat and cool for improved comfort and lower energy bills.
