As opposed to vinyl, fiberglass can withstand and endure any weather condition: rain, ice, snow, sleet and hail. It is not only resistant to various chemicals and moisture, but it is also reinforced with acrylic coating, which has proven to be 5x more malleable to the most demanding of conditions. Not to mention, it can withstand the degradation process five times greater than traditional..


Ultrex, a pultruded fiberglass material found in all of our Infinity replacement windows, is 8x stronger than traditional vinyl, making it virtually impervious to the most severe conditions. This can be attested to Marvin’s approach toward utilizing a mechanically-bonded finish.

Enhanced Flexibility

Our products bend but don’t break! Fiberglass is 833% less likely to expand or contract compared to vinyl. With this comes enhanced flexibility and structural integrity, assuring you that our windows won’t fold under pressure.

Advanced Engineering

Our windows require 39% less resources to produce than vinyl competitors. Using the most modern technology, our panes are joined and fixed by mechanical bonding, thus making our products more resilient and durable, while allowing you to maximize your view.

Aesthetically Pleasing

Marvin windows are coated in acrylic, giving them an unrivaled luster and shine. Additionally, they are easy to install and do not require bulky wood that is often required with vinyl. Most often than not, Ultrex technology prevails.

Proven and Trusted

Ultimately, vinyl is quicker to deteriorate, age, discolor and show blemishes than Infinity fiberglass windows, which are 5x more resistant to these changes and have an overall longer lifespan, performing at superior levels. Suddenly, the choice becomes obvious.
