Bi-Folding Patio Doors by Krasiva®


Bi-folding patio doors, also called accordion doors, are made with several hinged glass panels that move along a track. As the door opens, the panels fold and stack together at one or both sides of the opening.

Unlike a standard sliding door or multi-sliding door, which typically leaves at least one panel in place, a bi-folding door can open most of the available doorway. The result is a beautiful transition between your home and your patio, backyard, pool area, or outdoor kitchen.

The Krasiva® Difference in Bi-Folding Doors:


We offer bi-folding doors in several different manufacturers of different product types:

• Vinyl (Aluminum reinforced) bi-folding doors from Windor 3750
• Aluminum Clad-Wood bi-folding doors from Weather Shield
• Architectural Thermally-Broken Aluminum bi-folding doors from Windor 4750

Bi folding doors are highly specialized products with the most moving parts of any door system. To create the folding action requires many different types of hardware incorporated into the door system. They require highly experienced installers to configure everything correctly or it will not operate very well, or for very long. There are also a lot of structural concerns that have to be addressed prior to installing one.

The panels swing out and most of them have the rollers on the top and are hung from the support header above instead of rolling on the ground. Because they roll from the top, the rollers stay cleaner and they are among the easiest of doors to operate or to slide back and forth.

If the header sags in the middle after adding the additional weight of the door system to it, the panels will not stack to the side and stay there. Sometimes this requires replacing an existing header for a stronger one. At Krasiva Windows & Doors, we do all the framing necessary to make sure the door will operate correctly and we can even cut-in a wall to create a new opening in the back of the house to install a new bi-folding door. That includes all the drywall work stucco work and so forth.

Our in-house installers are paid hourly, dedicated to placing quality bi-folding installation over quantity for every project.

American Made Bi-Folding Doors:

Because they are also among the most expensive types of door systems, Phoenix has been inundated with European and Chinese models being imported into United States to try to grab the market share.

We have received many calls for help from customers who have purchased these unique doors from someone because they can’t get help when they need replacement parts or service with them. Servicing the products is not the goal of these foreign corporations; it is to get the initial large investment. We stick with American-made units because they are serviceable and these manufacturers must live with the products that they make.

Benefits of Bi-Folding Patio Doors

Create a Wider Patio Opening
The most noticeable benefit of a bi-folding door is how much of the doorway can be opened. Because the panels fold and stack together, large bifold patio doors can create a much wider passage than a traditional two-panel sliding door or even a multi-sliding door.
This makes it easier for people to move between the interior and exterior during family gatherings, parties, and other special occasions.
Improve Your Outdoor View
Replacing an older patio door or wall section with a folding glass system can provide a more open view of your backyard, pool, patio, or Arizona landscape. When the doors are fully opened, you can enjoy an unobstructed view of the entire opening without unsightly vertical bars blocking the scenery.
Make Entertaining Easier
Bi-folding doors are especially popular near kitchens, great rooms, dining rooms, outdoor kitchens, and covered patios. Opening the complete door system can make it easier to serve food, arrange seating, and keep guests connected.
Maintain Convenient Everyday Access
Some configurations include a hinged access panel that can operate similarly to a standard hinged patio door. This allows you to enter or exit without folding open the complete system every time.
