Performance Glass
Low E1
Primarily used in colder climates, Low E1 allows more heat in (maximum solar heat gain) to warm a room while blocking heat loss (radiant heat transfer). Achieve maximum benefits when used on elevations with direct sun exposure. Low E1 has one layer of metallic coating.
Low E2
By reflecting heat back to its source, Low E2 offers year-round performance in moderate climates. Low E2 will help retain heat (solar heat gain) in your home during the winter and keep heat out during the summer. Low E2 has two layers of metallic coating.
Low E3
Low E3 is formulated to reject solar heat while letting light in, resulting in increased performance in climates with intense sun exposure. Low E3 has three layers of metallic coating.
Low E4/ERS
With an extra metallic layer on the room-side glass to reflect escaping heat back into the room, Low E3/ERS provides maximum efficiency year-round in all conditions. Low E3 has four layers of metallic coating.
Interior
We use the same acrylic finish on our interior as on our exterior for superior performance. Or choose EverWood®, our stainable engineered wood grain finish, to blend seamlessly with your existing décor. All offer virtually no maintenance — just remarkably reliable performance.
Specialty Glass
Tempered
Increases glass strength to help prevent breakage. This option is ideal for windows and doors that are close to the floor or located in high-traffic areas
Laminated
Even more durable than tempered glass, laminated glass is often referred to as impact resistant or safety glass due to its vinyl interlayer that tends to remain in place when cracked.
STC/OITC
Sound Transmission Class and Outdoor-Indoor Transmission Class Glass has increased pane thickness, ideal in areas where exterior noise is a concern.
Decorative Glass
Decorative glass for replacement windows lends both privacy and style to any room while bringing in natural sunlight. Infinity from Marvin replacement windows have a selection of decorative glass styles to choose from. Consult with your Windows of Wisconsin sales person to choose the right glass for your space.







Simulated Divided Lites
Our Simulated-Divided-Lite (SDL) bars are built with Ultrex® fiberglass and permanently adhered in our factory to the outside surfaces of the glass. SDLs have a spacer bar between the panes of glass to offer the traditional look of divided lites.

Grilles
Grille bars are located between the panes of insulating glass. Grilles-Between-the-Glass (GBG) combine easy cleaning with the timeless detail of a grille pattern.
Patterns
We offer various divided lite patterns so you can replicate the look of your original windows and doors – or add new architectural interest to your home. Ask your local Infinity partner about additional patterns and style options.
