Energy-efficient glass options
Double-pane windows
Infinity's standard double-pane glass consists of two layers of glass with an insulating air space between them, providing enhanced thermal efficiency. Double-pane glass is exclusively available with the Traditional window profile.
Triple-pane windows
Triple-pane glass is exclusively available with the TriVue™ window profile and features three layers of glass separated by insulating air spaces, compared to the two layers found in standard double-pane windows. Triple-pane windows are the most energy-efficient window option.

Decorative glass
Ideal for the space that calls for natural sunlight indoors, decorative glass allows you to create the perfect combination of style and privacy in your new Infinity replacement windows and doors. Make a beautiful statement by choosing one of Infinity's decorative glass options.1
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.
California Fire Glass
A dual pane option where one pane is made of regular or annealed glass and the other pane is made from tempered glass, meeting California fire zone code. Infinity windows are not fire-rated.2
1. Obscure glass is the only decorative glass option available with TriVue™ window profile.
2. California fire glass is not available with the TriVue window profile.

Low-E glass glazing options
Low E1
An option for colder climates — especially those at elevations with direct sun exposure. A single layer of coating allows UV rays to warm your home while blocking heat loss.
Low E2
Low E2 features two layers of coating that reflect heat back to the source. This glass performs year-round in moderate climates, retaining heat in the winter and keeping it out in summer.
Low E3
With three layers of coating, Low E3 keeps solar heat at bay while letting visible sunlight into your home. A popular option for climates with intense sun exposure.
Low ERS
Available in conjunction with Low E2 or Low E3, this additional layer of coating is added to the room side of the glass. Low ERS reflects heat back into the room for maximum year-round energy efficiency.
Simulated Divided Lites
Our Simulated Divided Lites (SDLs) 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.1
Grilles Between the Glass
Grille bars are located between the panes of insulating glass. Grilles Between the Glass (GBGs) combine easy cleaning with the timeless detail of a grille pattern.
1. With the TriVue™ window profile, SDLs are only available for special shape and round top windows.

Frequently Asked Questions
Single-hung windows are considered more energy efficient because the upper sash does not move, which means a lower possibility of air infiltration. Since double-hung windows have two operable sashes, the possibility of air infiltration can increase.
Infinity by Marvin's easy tilt operation allows you to clean your single-hung windows from inside your home. After raising the lower sash, press the tilt release button and tilt the sash toward the room. From there, use an Infinity-approved cleaner and our window cleaning tips.
In a Cottage window, the lower sash is taller than upper sash.
An Oriel window has two unequal sashes. In an Oriel window the top sash is taller than the bottom sash.
Single-hung windows have the advantage of fitting into nearly every room in a home. They can work especially well in bedrooms and bathrooms where you want just enough ventilation and don’t need an operable upper sash.
The difference between single-hung and double-hung windows is the number of moving parts. A single hung window only has one sash that slides up and down to open. A double hung window features two sashes that open and close.
Single-hung windows costs depend on several factors. The installation method, design options, and glass glazing choices all impact the cost of a single-hung window. An Infinity by Marvin expert can review options with you.
