WHAT IS ULTREX PULTRUDED FIBERGLASS?

Infinity windows and doors are made with Ultrex® , a patented pultruded fiberglass with acrylic capping.  Infinity's uses Ultrex and proprietary a pultrusion process to manufacture high-performance windows and doors that endure heat, cold, wind, and rain without wearing out. In other words, it is the perfect window material.

 

Ultrex fiberglass has an amazing strength-to-weight ratio, which is one of the reasons why it’s the material of choice for boats, bridges, guard rails, and ladders. It’s highly durable, doesn’t corrode, resists rot, and resists expanding and contracting in temperature swings.  In comparison to longitudinal tensile strength.

What is Pultrusion?

“Pultrusion” combines the words “Pull” and “Extrusion.” Extrusion is pulling of material such as Fiberglass and Resin, through a shaped and heated die.

 

What is the Pultrusion Process?

Fiberglass materials used in the manufacturing of Infinity from Marvin replacement windows go through a pultrusion process. Pultrusion is a continuous molding process using fiber reinforcement in polyester or thermosetting resin matrices. Heat is used on the "thermoset" resins, in the fiberglass pultrusion process, to cause an irreversible chemical reaction which permanently sets the shape of the fiberglass window frames. Once the Ultrex is cured, it cannot be reformed; this process is permanent.

Pultruded fiberglass materials are made of glass fibers and resins. The glass used in fiberglass, while basically the same core material as that used in flat glass, comes in a different form – rovings – or also known as fibers.  This form of glass begins as a finely ground, flour-like material composed of Silica and Zirconia. The "flour" is heated and melted at approximately 1500° C, and the resultant molten glass is passed through small holes forming hair-like filaments. The filaments are collected together, grouped and a binder is applied to bond them into strands. Then the strands are heat cured, wound together and rolled up into a cylindrical package. These fibers provide the bulk of fiberglass profile's longitudinal strength.

The majority of resins used for fiberglass window profile are classified as polyesters. Polyester resin is one of a group of synthetic resins which undergo polymerization during curing. They provide excellent adhesive properties, high strength, and good chemical resistance. These high-performance polyester resins are then mixed with suitable fillers and pigments to formulate the resinous matrix. The formulations are optimized for the particular application.

 

1. Increased Strength (fiber processed under tension)

2. High Fiber Content

3. Low Expansion

4. Consistent Quality

Infinity from Marvin Ranked #1 in J.D. Power Study

The window and door replacement line received top honors in customer satisfaction study.

Infinity from Marvin earned number one for customer satisfaction in J.D. Power 2019 Windows and Patio Doors Satisfaction Study in the manufacturer segment. The study measures satisfaction among customers based on performance in three factors: appearance and design features; operational performance and durability; and warranty.

Infinity from Marvin ranked highest with a satisfaction score of 890 based on a 1,000-point scale.

"We’re not focused on being the biggest window and door replacement company — we’re focused on being the best,” said Dan Marvin, President of Infinity from Marvin. “Earning the number one position on the J.D. Power customer satisfaction study is wonderful recognition of our team’s continual efforts to make every step of replacing your windows as simple as possible and backing it up with innovative products and timeless design."

The global leader in consumer insights surveyed 2,913 customers in three performance areas who purchased windows or patio doors within the previous 12 months. The study was fielded January – May 2019. For more information about the J.D. Power 2019 Windows and Patio Doors Satisfaction Study, visit jdpower.com/awards.
