Impervious to Temperature Change

Ultrex resists such things like thermal expansion and contraction to provide the most comprehensive window and door product available today. While vinyl can distort in extreme heat or even streak and crack, Ultrex fiberglass offers the highest level of thermal performance. They expand 833% less than vinyl and 300% less than any wood and vinyl composites. Containing 0% vinyl, the pultruded fiberglass that makes up Marvin’s innovative Ultrex can withstand temperature from 40 below to 350 degree above. Because of its extremely low thermal expansion rate, your Infinity from Marvin windows will be stable and weathertight, dramatically reducing the risk of seal failures and air leakage into your home.


Amazing Durability and Longevity

The low expansion of Ultrex means less sticking, swelling, and warping. It resists discoloration, warping, rotting, corrosion, denting, rust and doesn’t require sanding, scraping, or painting. Marvin’s Ultrex fiberglass also meets requirement 623-10 of American Architectural Manufacturers Association (AAMA), an association that voluntarily publishes specifications for organic coatings on fiber-reinforced thermoset profiles. Qualifying for AAMA 623-10 requirement means that Ultrex is a window material with extremely high durability. It does not suffer corrosion, blistering, or peeling even when exposed to acid, baked in a hot oven, and placed in extremely cold temperature!
