Lifetime Windows & Siding uses Ultrex fiberglass because the material you choose for your windows matters. Ultrex is 8X stronger than vinyl. Because Ultrex is so strong, we actually use less of it in Infinity window frames. That means you get more daylight and greater views outside coming through your window. If you're considering a replacement window project, Infinity from Marvin windows is your choice for a lifetime.
