The Story of Infinity® from Marvin Windows Made in Minnesota

The Marvin® windows brand has a serious commitment to environmentalism and sustainability in the communities they serve.

The History Of Infinity® From Marvin

Marvin has provided customers with premium-quality windows and doors for more than 100 years. As one of the largest manufacturers of made-to-order window and door products, Marvin continues to lead the industry in product design and function. Family-owned and operating under the leadership of the 4th generation, Marvin has grown to become an iconic Minnesota company with exceptional sales and service support.

Infinity® Replacement Windows

The Infinity® from Marvin Window line was created in 2002 when the company recognized a need for high-quality fiberglass windows and doors. Lindus Construction is an exclusive dealer for the Infinity®  Windows brand which can provide our customers with the traditional look of wood windows, but they are made out of Ultrex® fiberglass. Their design experience and superior materials made our decision easy when we chose to align ourselves with this Minnesota company.

What Sets Infinity Ultrex® Fiberglass Apart?

Infinity® windows and doors are made from a superior material technology called  Ultrex® fiberglass.

 

Strength, Performance, & Aesthetic With Every Window Installation

Ultrex® is comprised of strong cables of glass that are saturated with compound resins that are pulled through a heated die and cut with diamond-edge blades. Ultrex® is formed and cured all the way through the manufacturing cutting stage. This patented process creates an unmatched durability that will outlast and outperform other fiberglass windows.

Durability Infinity® Windows Are Built To Last

Ultrex® is eight times stronger than vinyl, making it as strong as low carbon steel. The product is so durable that it requires diamond-edged blades to penetrate the material when cutting it to size. Ultrex® possesses superior stability, resulting in windows that have unbeatable performance and are low-maintenance.

The Ultrex® Fiberglass Window Difference

  • Low maintenance
  • Replicates the look of traditional wood windows
  • Easy operation for the life of the window
  • Unmatched strength keeps windows square and true
  • Narrow profiles for more visibility and expanded views
  • Long-term stability helps eliminate seal failures and air leakage through the window
  • 8x stronger than vinyl
  • 38% longer useful life expectancy than vinyl

Energy Efficient Windows

The Marvin® Infinity® Windows line offers a variety of flexible and customizable window and door options that help balance the product investment with long-term performance and energy cost savings.

Glass & Glazing

Infinity® from Marvin® Replacement Windows offer a range of glazing options to meet the performance challenges of any climate. Insulating gasses are pumped in spaces between the glass to slow the transfer of heat. All of these windows come standard with Low E2 and argon gas, but since all Marvin® products are made-to-order, you are able to add krypton gas to this blend which will increase the insulating capabilities of the window. Their glass and glazing techniques will suit any energy efficiency needs your home desires.

High Performance Tripane Glazing

Tripane glazing, available with argon or krypton insulating gas, provides excellent energy performance.  Tripane features two coated panes of glass with a third pane between them. Marvin® windows offers Tripane in a variety of Low E glass options.  Many Tripane glazed units have U-Factors less than 0.25, and fixed or combination units can be lower than 0.20 without sacrificing visible light transmission. Available in products where glazing thickness can be wider than ¾”.

We love our new windows, and patio door!! We were very pleased with every team member. Starting with customer service all the way to the installation."

"We purchased a new back door and storm door that were installed in late December. The storm door had not been shutting properly, and Wayne from Lindus arrived to fix it. Not only did Wayne correct that problem, he thoroughly went through each function of the door, hinges, handle, and shutting device. In some cases, he replaced the 3-month-old parts because they weren’t working properly. By the end of his service call, we felt like we got a completely improved door from the manufacturer. In today’s service world, it is very rewarding as a customer to see an employee of a company care so much about making it right for the customer."
