Ultrex Fiberglass

Nothing’s Tougher?
Infinity® from Marvin's interior and exterior are made entirely of Ultrex. This fiberglass material is so durable, so long lasting, so strong, you'll never have to worry about replacement windows again. Best of all, it makes Infinity windows essentially maintenance free. All the while not compromising our environment.

The Ultimate Material for Replacement Windows
Made of pultruded fiberglass - thin, strong cables of glass, saturated with specially compounded resins -Ultrex is a revolutionary material that outlasts and outperforms other window materials.

What makes Ultrex clearly superior?

• Strength - It is 8x stronger than vinyl, 3.5x stronger than wood composites and 3x stronger than wood. This allows for narrow frame profiles for more visible glass area.
• Low Thermal Conductivity - 500x less conductive than aluminum; which means Ultrex doesn't conduct heat or cold from the outside into your home.
• Stability - Low thermal expansion rate (essentially the same rate as glass) means less material movement for better seals and longer endurance.
• Durability - Won't discolor, warp, rot, corrode, dent, rust and never needs sanding, scraping or painting. 5x more resistant to UV degradation than vinyl – even with dark colors like Bronze.

The Manufacturing of Ultrex
Tecton Products, the manufacturer of Ultrex, takes their effect on the environment very seriously. So much so, they set the highest standard in the industry for the destruction of pollutants. They destroy more than 96.9% of volatile organic compounds. The Environmental Protection Agency has certified the emissions control technology at Tecton Products to be the maximum achievable control technology, placing them in full compliance with the 1990 Clean Air Act. Their processes don’t produce any sewage waste and all styrene vapors are destroyed with no emissions.

Not only does Tecton Products engage in environmentally sound manufacturing processes, Ultrex in and of itself, is inherently environmentally safe. Ultrex has a high mineral content, which is mined and requires minimal processing. There are no waste streams intrinsic to the pultrusion process and the only continuous source of scrap are chips and dust from fabrication. Both of which are non-leaching and landfill safe.

Ultrex allows for Infinity® from Marvin's high energy efficiency, thereby reducing heating and cooling costs and energy usage. Because Infinity is made of this pultruded fiberglass called Ultrex, fewer natural resources need to be used to achieve its superior strength to weight ratio.
