Amazing Strength


boy holding on to window frame

The same amazing strength-to-weight ratio and tensile strength that make pultruded fiberglass perfect for use in ladders, bridge construction and guard rails make it perfect for durable, low-maintenance windows and doors. It’s eight times stronger than vinyl and almost twice as strong as steel. That’s why Ultrex forms the stiles and rails of every Integrity product that leaves our state of the art manufacturing facility. The result: superior strength, durability, performance, energy efficiency and finish.

Thermal Expansion

Ultrex can stand up to extreme heat, because it expands at virtually the same rate as glass, which means the entire window sash will stay tightly sealed-no cracks in the material or leakage around the glass. On the other hand, vinyl can distort in extreme heat due to its high thermal expansion rate. So over time, it can spot, streak and crack. And painting vinyl to mask the problems simply makes it worst by making the vinyl more brittle.

Energy Efficiency: An Energy Star is Born


energy star logo

ENERGY STAR qualified windows can save you fifteen percent of your total energy bill. And Integrity from Marvin products don’t simply qualify for the energy star rating; they exceed its performance requirements. That’s because Ultrex is 500 times less conductive than aluminum. Argon gas, which has thermal conductivity 30% lower than that of air, and a warm-edge spacer also contributes to Integrity’s energy efficient products.

Beautiful in your home. Kind to the planet.


SFI logo
From creating energy efficient windows with a life cycle that far outlasts the competition, to ensuring Integrity lessens their impact in all steps of manufacturing, they provide windows that make the homes we build part of a greener and brighter future. Ultrex is made with 10% recycled material and the glass in the products contains 15%-33% recycled content. All wood components use Sustainable Forestry Initiative (SFI) wood to ensure sound environmental stewardship. Integrity has been and continues to be an active participant in community, state and industry initiatives to improve environmental manufacturing practices.
