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.

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 E3/ERS:
With an extra metallic layer on the room side of the glass to reflect escaping heat back into the room, Low E3/ERS provides maximum efficiency year-round in all conditions. Low E3/ERS has four layers of metallic coating.

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.

Our Simulated Divided Lite (SDLs) 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 (GBGs) combine easy cleaning with the timeless detail of a grille pattern.

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.

Add the finishing touch with our variety of hardware finish options.

We offer two screen options — our standard, a durable aluminum-surround screen with Bright View fiberglass mesh (shown left), or Hi-Transparency for a clearer view (shown right).

Our optional EverWood-wrapped screen provides a seamless look that can be stained to match your interior trim.
