PIONEERS OF FIBERGLASS REPLACEMENT WINDOWS
Fiberglass has an astounding strength-to-weight ratio, which is one of the reasons why it’s the material of choice for boats, bridges, guardrails, ladders, and hardhats. Imagine a ladder or a bridge made from vinyl!
Fiberglass is highly durable, won’t leak or corrode, resists rot and doesn’t expand and contract in Denver’s extreme temperature swings. These properties make Infinity from Marvin’s Ultrex fiberglass 800% stronger than vinyl and a far more durable material. Vinyl replacement windows can't stand up to Colorado's UV and temperature swings, meaning they are only a short-term solution for your home.
How does all of this come together for window replacement? Infinity from Marvin fiberglass windows expands at the same rate as glass, which means our replacement windows stay tight and true making them impervious to leaks, seal failures and stress cracks that can compromise energy efficiency and long-term performance. Vinyl windows are plastic. You might save a little on vinyl windows at first, but for total value and durability, Marvin's patented ULTREX fiberglass is the smart way to replace your windows. Plastic is cheap...think FIBERGLASS!
