Why do homeowners love Infinity from Marvin fiberglass 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 hard hats.  Imagine a ladder or a bridge made from vinyl!

Unlike vinyl windows that are susceptible to sagging, warping, and chalking, fiberglass windows are created from glass fibers and resin. This composition gives the frame a structural integrity that outlasts most other materials and doesn’t need any maintenance. Even after prolonged exposure to the elements, fiberglass won’t rust, dent or corrode.  Infinity fiberglass windows are perfect for your home and the Colorado weather!
