Peace of mind. With a view.

Infinity windows are made from Ultrex^® fiberglass, inside and out. Marvin has nearly two decades of experience creating window and door products made with this strong fiberglass material. The reason we chose it for Infinity windows and doors is simple: fiberglass is superior to other window materials in virtually every category

Made with strong cables of glass that are saturated with specially compounded resins, Ultrex^® is durable, no-corrosive, has low thermal conductivity, and is low-maintenence. The superior strength of Ultrex^® fiberglass allows the window frame profile to be narrower than those with frames made of vinyl or wood, giving you more visible glass area. And no matter how extreme the temperatures get in your region of the country, Ultrex^® stays square and true.

Stronger than steel

For windows, the strength of Ultrex^® fiberglass means less material movement for better seals and long-lasting windows and doors. Tough, dependable, non-corrosive, non-brittle and low-maintenence, Ultrex^® is the last word in replacement windows and doors.

Energy Efficiency

Ultrex^® fiberglass is far less thermally conductive than aluminum (500x less!) and insulates much like wood and PVC. This means that Ultrex^® provides an insulated barrier against extreme weather temperatures, keeping your home comfortable, and helping to reduce heating and cooling costs. As proof, Infinity products have one of the highest performance ratings from the National Fenestration Rating Council (NFRC), the organization that defines energy performance ratings for the window and door industry

Built Green

In addition to building products that are long lasting and highly energy efficient, our construction materials are kind to the planet as well. Ultrex^® fiberglass is made of partially recycled material, and the main ingredient of Ultrex^® fiberglass is silica sand, an abundant natural resource. The glass in our products contains 15% - 33% recycled content. Additionally, Ultrex^® requires 39% less energy to produce than vinyl.

Two Convenient replacement Methods

Depending on the age and style of your home, Infinity^® from Marvin offers two window and door replacement methods. Both methods are designed for maximum efficiency and minimum disruption to your household.

Insert Replacement

This replacement method is used when your existing window frames are in good condition, but the sash needs replacement. Our frame-in-frame insert design is installed into your existing window frame with no disruption to existing trim, interior walls or exterior siding. This method is fast, efficient and economical, and there is no finishing required on your part.

Full-frame Replacement

This installation method is appropriate when your entire window has deteriorated and needs replacement or if you are looking for a totally new window size, style, or appearance. With full-frame replacement, the entire window (sash, frame, and casing) is removed and replaced.

French and Patio Doors

Add the finishing touch to your home with French Doors and Patio Doors that provide the same durable, low-maintenance exterior as your Infinity windows. Two door brands are available for you to choose from, both impervious to the elements thanks to Ultrex^® fiberglass exteriors. Integrity^® Sliding Patio Doors and Swinging French Doors feature a natural wood interior and are available in bare wood or with a white semi-gloss finish. Sliding French Doors from Infinity are low-maintenance fiberglass on the exterior and interior and are available in Stone White, Sierra, or with a completely low-maintenance EverWood^® stainable interior.

Double Hung

You've heard it said, "Don't work harder. Work smarter." With old double hung windows, you can work up a sweat just opening them and keeping them open. THe Infinity^® Double Hung is the smart answer to a traditional favorite. You'll be amazed at its smooth, effortless operation. Quality hardware and advanced design result in a double hung that makes cleaning so easy, you may actually have volunteers. Make the smart window choice and your "window worries" will become a thing of the past.

Casement and Awning

One word describes Infinity^® from Marvin Casements and Awnings - easy. They are easy to choose, easy to operate and easy to love. The Casement (left or right hinged) and Awning (top hinged) combine beauty and virtually effortless operation. The standard Easy Wash^® hinge is just that - a design that lets you easily clean the window both inside and out. The optional Clear View^® hinge provides for an optimal viewing area. Both Casements and Awnings feature folding handles that tuck conveniently out of the way of most window treatments and provide a clean, finished look.

Glider

If your gliders don't "glide" anymore or you have a space where a swinging sash would be in the way, the Infinity^® Glider is the perfect solution. These durable, energy-efficient windows operate smoothly and seal tightly against air, and water infiltration. Made with tough, dependable Ultrex^® fiberglass inside and out, our Gliders are virtually maintenance-free. You'll also appreciate the superior performance and energy efficiency provided by standard Low E II with argon insulating glass. Cleaning the glass is simple with tile latches that allow you to remove the operable sash for easy access.

Bay Window

Invite nature in - create interest and add drama to any room with the simple combination of three windows set into the Infinity^® Bay. Your home will enjoy the low-maintenance interior and exterior while you enjoy the expanded views. From a small sunlit area for plants to an expansive reading nook, the Infinity^® Bay can work into any area of your home with two angle options of 30 and 45 degrees. Choose Double Hung or Casement windows for your Bay with head and seat boards included.

Bow Window

The Infinity^® Bow offers an easy way to expand your views and open up a room. The gentle curve can be created with four, five or six wide assemblies of Casement windows. Head and seat boards are included in Bare Pine (or optional Oak) to allow for staining or painting to match your home's interior.

Easy Tilt Operation

Our Double Hung window is amazingly simple to operate, and both lower and upper sash tilt with ease, without removing your screens. Our unique tilt release button lets you tilt the lower sash using only one hand, so cleaning is easier than ever.
