Infinity Bi-Fold Doors are available in a variety of styles depending on door operation. To create a balanced and aesthetically pleasing space, consider installing a bi-parting bi-fold door that opens from the center, symmetrically framing your view.
For those looking to maximize their view, a uni-directional bi-fold door is an excellent choice, as it allows you to stack the panels completely to one side, offering an expansive, unobstructed view. You can choose whether the panels stack to the left or right, depending on your preference.
Additionally, for everyday convenience, you can add an optional access panel to some uni-directional bi-fold door configurations, providing easy access without needing to open the entire door.

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.
Performance glass
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.
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.

Simulated Divided Lites
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 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.

Frequently Asked Questions
Yes, Infinity Bi-Fold Doors come with a pleated fabric screen that can open from both sides and be positioned as desired.
Bi-fold patio doors create a tight seal when closed to prevent unwanted hot air or water from entering your home. Plus, Infinity has glass coating options that can help reject solar heat.
The tight seal bi-fold doors have when closed helps prevent unwanted air and moisture from entering your home. If you want to operate your bi-fold door in winter, make sure the area the door opens out to remains clear of snow. Bi-fold doors can have an access door that operates as a French door so you can enter and exit without opening the entire bi-fold door.
Widening an existing opening depends on the intended space for a patio door. If we need to cut the structural opening, you'll need a structural engineer to verify the site has the capability to do so.
Bi-fold patio doors use a twin bolt handle to lock the door. Lifting the handle 45 degrees upward will set the head and foot bolts in place for a secure seal. The deadbolt in the handle assembly locks with a 90 degree turn of the key from the outside or with the thumb turn on the inside. The twin bolt handle rotate up to 180 degrees and to lock the bi-fold door, rotate the handle down.
You can also select keyed door handles from our Northfield and Cambridge collections.
Bi-fold doors create indoor-outdoor living in your home and help create outdoor kitchen, dining room, and entertainment areas where you don’t need to open and close a patio door each time you move between the indoors and outdoors.
Bi-fold doors open like an accordion and the panels stack tightly on top of each other. The panels slide along a track as you open the door and a magnetic catch ensures the panels stack tight. Infinity by Marvin Bi-Fold Patio Doors have up to 28 configurations, including ones with a swinging door for quick indoor-outdoor access.
No, accordion doors are not soundproof. If you’re concerned about outdoor noise, you can choose options like Infinity's Sound Transmission Class/Outdoor-Indoor Transmission Class glass for your bi-fold door. The glass features increased pane thickness, perfect for areas where outdoor noise is a concern.
Infinity by Marvin accordion doors cannot be shortened. If you’re limited on space for a bi-fold door, we do have configurations that feature just two panels.
