Infinity—Building on the Marvin legacy

Our history

Marvin began in 1912 as a family-owned cedar and lumber company with a vision to improve how people live. Over the past century, the company has evolved into a leading manufacturer of windows and doors, consistently raising the bar for quality, beauty, and simplicity in everyday life. In 2002, Marvin introduced Infinity as its dedicated replacement window brand, designed to deliver the same craftsmanship and performance that define Marvin’s legacy. Today, both Marvin and Infinity continue to help homeowners create spaces that feel healthier, happier, and more connected.

Innovation with Ultrex fiberglass

Ultrex fiberglass is a proprietary material designed for exceptional strength and long-term performance, surpassing vinyl and vinyl/wood composites in both durability and style. Developed by Marvin, this advanced material combines superior resilience with timeless design. Ultrex is used on both the interior and exterior of Infinity by Marvin products and is also featured in the Marvin Vivid™, Marvin Elevate^®, and Marvin Essential^® collections. Engineered for lasting beauty and reliability, Ultrex sets the standard across a range of premium window and door solutions.

Marvin adds replacement products

Marvin broadened its scope in the late 1990s to reach even more homeowners and provide best-in-class solutions for their window and door needs. Building on the success of the Ultrex fiberglass exterior option, and recognizing an additional market opportunity, the Marvin company decided to focus on a part of the market segment they had limited presence in — replacement windows and doors. Homeowners had been using Marvin products for replacement projects for years, the only issue was the products they were using were designed for new construction with rough openings. This meant in every replacement scenario, the entire window and door, including the frame, would have to be completely removed from the opening. This worked, however, in many instances structurally sound frames were being needlessly removed and discarded.

At this time, insert replacement products were making a surge in the window replacement industry. This meant if the window’s original wood frames were in good condition, they could be left within the wall and a new replacement window could be installed using a frame within frame installation. Marvin needed a window that utilized this insert replacement approach.

Infinity's origins

Identifying a market need for premium fiberglass replacement windows and patio doors—and establishing a network of trusted partners to sell, install, and service these products—Infinity was created to stand out as a true innovator in the replacement industry. Officially launched in October 2002 as Marvin’s dedicated replacement window line, Infinity was founded by Dan Marvin and Tom Goldsmith, who continue to guide the company’s vision and leadership today.

A modern evolution

In 2025, Infinity entered an exciting new chapter with a refreshed brand identity. The name changed from Infinity from Marvin to Infinity by Marvin, accompanied by a redesigned logo that reflects a cleaner, more modern aesthetic. This evolution was driven by two key factors: first, to streamline the logo for a minimalist look that aligns with contemporary design trends; and second, to adopt the naming convention many homeowners were already using when referring to the brand. The update reinforces Marvin’s heritage while highlighting Infinity’s unique focus on replacement solutions.

Looking ahead

As Infinity by Marvin continues to grow, the goals have remained the same — to produce a line of high-performance replacement windows and doors and provide a stress-free experience from initial consultation to window and door installation.
