Our bi-fold door instantly upgrades your indoor-outdoor living style with modernized design and operation. Enjoy a panoramic scenic view with our bi-fold door whether you're entering guests or daydreaming from inside your home.

The accordion style of the bi-fold door allows a rush of fresh air into your home. Bi-fold doors can come as bi-parting doors, meaning it opens in the middle, uni-directional where the door opens to the left or the right, and uni-directional with an access panel that swings open and closed.

Worried about bugs? Our pleated fabric screen is available to keep the bugs out of your home when you have your bi-fold door open.

Glass Coatings

Our experts will walk you through energy efficient glass options to find the right selection for your home and the best patio door for your space. Choose from four glass coatings, plus decorative glass options, and specialty glass choices.

Low E-1

Primarily used in colder climates, Low E1 allows more heat in to warm a room while blocking heat loss.

Low E-2

Low E2 offers year-round performance in moderate climates. It will help retain heat in your home during the winter and keep heat out during the summer.

Low E-3

Low E3 rejects solar heat while letting light in, resulting in increased performance in climates with intense sun exposure.

Specialty Glass

We offer specialty glass to best suit the needs of your home. You can choose tempered glass, laminated glass, and STC/OITC glass for specific windows and rooms.

Tempered Glass

Tempered glass increases glass strength to help prevent breakage. Tempered glass is ideal for windows close to the floor or located in high-traffic areas.

Laminated Glass

Even more durable than tempered glass, laminated glass is often referred to as impact resistant or safety glass due to its vinyl inter layer that tends to remain in place when shattered.

STC/OITC Glass

Sound Transmission Class and Outdoor-Indoor Transmission Class glass has increased pane thickness on the room side and works in areas where exterior noise is a concern.

Hardware

Choose from one of nine hardware finishes, depending on the handle style, for your bi-fold patio door. Or, choose a Twin Bolt Handle in Black or Brushed Stainless Steel color. Rotate the interior Twin Bolt Handle up 180 degrees to unlock and open the door, rotate down to lock and secure.

Choose a Black or Brushed Stainless Steel color for a magnetic door catch to keep door panels in place when you open the door.

Frequently Asked Questions

Do Bi-Fold Doors come with screens?

Yes, Marvin Replacement Bi-Fold doors come with a pleated fabric screen that can open from both sides and be positioned as desired.

How do bi-fold doors do in warm climates?

Bi-Fold patio doors create a tight seal when closed to prevent unwanted hot air or water from entering your home. Plus, Marvin Replacement has glass coating options that can help reject solar heat. Find out more about our energy efficient windows and doors.

How do bi-fold doors work in winter?

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. Check out our bi-fold door in action.

Can you widen an existing opening for a patio door?

Widening an existing opening depends on the intended space for a patio door. If we need to cut the structural opening, we’ll need a structural engineer to verify the site has the capability to do so.

How do you lock a bi-fold door?

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 patio door benefits

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.
