Planning a remodel to create indoor-outdoor living spaces? Choosing a Bi-Fold Door System can be a confusing process, especially if you are unfamiliar with this type of door system and its features. Below are nine mistakes you’ll want to avoid when including a large folding door system in your home design plans.

1 | Mixing up folding door configuration options.

When choosing a configuration (how the door panels open and fold) for your large folding door system, you want to be sure you are reading the configurations correctly. All Bi-Fold Door System configurations are viewed from the exterior of your home looking in. It is easy to get this confused and end up with doors opening and folding the opposite direction from what you were expecting.

2 | Choosing a door configuration without a daily door.

This mistake is easily made and happens often. It is important to choose a door configuration that will have a manual door, or “daily door,” that provides easy access to your outdoor space. Bi-Fold Door Systems with odd configurations (3L, 5R, 7L in at least one direction) have daily doors that can be opened without unlatching and opening the entire folding door system. You must choose a configuration with a daily door If you plan to access your home from the exterior of your large bi-fold door. If you choose an even door configuration (such as 4L or 2L2R) you will have to open the entire door system to access your outdoor space and you will not have exterior access if the doors get closed and you’re outside. Even configurations are only suitable for door systems that will only be opened for parties, etc. Never choose even configurations for a door you’ll use every day.

3 | Taking incorrect measurements.

Always have a professional installer measure your opening twice to be sure you are providing the correct measurements of your rough opening. Folding door systems are built to your requested net frame dimension, and if measurements are incorrect the unit will not fit properly into your rough opening.

4 | Not matching your bi-fold and transom design.

This mistake can leave your remodel looking unprofessional and tacky. If your plans call for a bi-fold door system paired with a transom, you want to be sure that your transom will match and align with your folding door design.

5 | Forgetting to check for overhang.

This is a big, costly mistake that you want to avoid. If you forget to check for overhang and order a bi-fold door system with a flush sill, you risk water penetration and serious damage to your home. A folding door system with a flush sill and insufficient overhang will not meet most warranties.

6 | Hiring an inexperienced folding door installer.

Bi-fold door systems are large, top-hung, technical door systems, that come with a pretty healthy price tag. Installation is not the right place to try to save money. Ask for recommendations for experienced installers of large patio door systems from your door dealer, or the manufactures of your bi-fold door system. Don’t trust framers or other tradespeople to install your beautiful new bi-fold door. An improperly installed door will never work properly, will not qualify for warranty, and will be your biggest regret. Hire a pro!

7 | Choosing the wrong clad color.

Don’t choose the wrong clad color, because it can’t be changed! If you are matching the exterior color of your folding door to your current windows and doors, make sure you double check and confirm that the color is correct. For unique or uncommon colors, custom color matching is also available.

8 | Forgetting to include a retractable accordion screen.

Don’t forget to include a retractable accordion screen in your folding door order! These screens are a luxurious but functional add-on that will allow you to enjoy fresh air while protecting your home from unwanted insects. Screens are integrated directly into the door jamb during production and can be pocketed completely out of sight for an additional charge.

9 | Overlooking your indoor and outdoor floorplans.

When planning your remodel it can be easy to forget about the layout of your spaces and how they interact. it is important to give some thought to the furniture layout of each space and remember that your custom patio door system can be ordered to fold and stack on one or both sides of the opening, depending on your needs.

If your home remodel plans include a custom Bi-Fold Patio Door, don’t forget to consider the various Bi-Fold Door configuration options. With more than 75 possible door configurations available, you are sure to find the perfect Bi-Fold Patio Door configuration for your space. Though all door configurations are equally as beautiful, we highly recommended sticking to a Bi-Fold with an odd number of panels.

We recommend Bi-Fold configurations with an odd number of panels to create a manual door with exterior access. Daily doors allow easy access to the outside without having to open the entire Bi-Fold System. Odd configurations work best when clients will be using it for regular patio access.

Bi-Fold configurations with an even number of panels do not have manual doors or exterior access. The entire Bi-Fold System must be opened for outside access. Even configurations work best in spaces like pool houses, which don't require frequent access. If using an even number of Bi-Fold door panels in your project is inevitable, you can create a daily door by choosing an odd configuration. For example, instead of a 4L or 4R Bi-Fold Patio Door, you can choose a 1L3R or 1R3L.

You may be planning a remodel soon and considering multiple large glass patio door options. If you are planning on creating an indoor-outdoor living space using Multi-Slide Patio Doors or Bi-Fold Patio Doors but are having trouble deciding between the two patio door styles, we have created a guide to help you determine which large glass patio door is perfect for you and your living space!

A custom four-bedroom, three bathroom Spanish style new build in Santa Barbara, California, uses AG Bi-Fold Patio Doors and French Swing Patio Doors to extend their living space to the outdoor balconies and patios.

The builder wanted to remain traditional with the Spanish style architecture that Santa Barbara is known for but incorporate modern luxuries to create a resort-style living experience. White stucco, red tile roofing, and a natural wood trim and pergola are the elements that give this home some character and Spanish flare. The front courtyard featuring a fire pit and outdoor seating, and the expansive verandas on the upper and lower levels are additional architectural elements representative of Spanish design.

The kitchen is located on the upper level and features exposed wood beams, a beautiful waterfall island with bar seating, and luxurious wood cabinets. The AG Bi-Fold Patio Doors create a connection between the kitchen and outdoor dining space on the veranda. The wood interior of the Bi-Fold Doors was stained to match the other wood elements inside the home. Large glass patio doors allow an abundance of natural light to illuminate the kitchen and allow plenty of fresh air to flow through the space.

The outdoor dining space is perfect for entertaining, with easy interior access through the folding patio doors. With such a large balcony, additional outdoor furniture will fit to create an entire outdoor living room! Four pairs of French Swing Patio Doors line the remainder of the veranda and create a seamless transition from living and dining room to outdoor balcony.

The floorplan is spacious, open, and airy with major indoor-outdoor living vibes created by the four French Door systems. Unique light fixtures give the spaces a modern touch and help to create separation between dining and living areas. The wood floors, exposed beams, and interior wood of the French Doors add warmth and create a beautiful contrast with the bright white paint on the walls and ceilings.

A second AG Bi-Fold Patio Door in the master bedroom creates a seamless transition between bedroom and outdoor patio area. The folding patio doors provide an expansive view of the surrounding nature and create access to the quiet outdoor space. The builder wanted the home to be well-connected to the outdoors because the home is surrounded by large oak trees, shrubbery, and flowers. The stone patio on the lower-level expands across the rear of the home and can also be accessed via the guest bedrooms.

The spacious and private downstairs guest bedrooms enjoy their own French Doors to increase light and create expansive views. A Jack and Jill bathroom sits between the two guestrooms and features luxurious marble countertops and a marble shower.

The builders were incredibly happy with how the home turned out and put the home on the market. They are confident that the future homeowners will fall in love with the home because of the indoor-outdoor living it offers. As the house is shown to many potential homebuyers and open-house goers, there is one common thought between visitors: the Bi-Fold Patio Doors make the space—their quality, uniqueness, and curb appeal are impressive and like no other.
