Exterior bifold doors

If you’re dreaming of a home that feels open, bright, and connected to the outdoors, exterior bifold doors might be just what you need. These stylish doors fold away to create a wide, open space between your home and your patio, backyard, or deck.

Whether you’re upgrading your space or building something new, bifold doors offer both beauty and function. Let’s break down what makes them so popular—and how to choose the right set for your home.

Exterior bifold doors are made of several panels that fold and stack to one or both sides, almost like an accordion. Unlike traditional sliding or French doors, bifolds can open up almost an entire wall, giving you a much wider entry and a seamless flow between inside and outside.

They’re often made of strong, modern materials like:

• Aluminum for a sleek, low-maintenance look
  
• Wood for warmth and natural charm
  
• Vinyl or fiberglass for extra durability
  

Most styles include large glass panels, which means even when they’re closed, you still get lots of natural light.

Adding exterior bifold doors is more than just a style choice—it can change how your home feels and functions. Here’s why homeowners across the country are falling in love with them:

Want your living room to flow into your backyard? Bifold doors let you open up wide and bring the outside in—perfect for parties, relaxing weekends, or enjoying warm weather.

Even when closed, bifold doors offer more glass than most sliding doors. That means your home stays brighter during the day, which can also help reduce your need for artificial lighting.

Exterior bifold doors are sleek and stylish. They give your home a high-end look and can raise its resale value too.

Don’t want to open all the panels every time? Some bifold doors come with a “traffic door,” which works like a regular door for quick ins and outs.

Bifold doors are perfect for any spot where you want more space, light, and access to the outdoors. Popular places to install them include:

• Back patios
  
• Decks
  
• Pool areas
  
• Balconies
  
• Outdoor kitchens or entertainment spaces
  

They also work great in homes that have open-plan designs. When the doors are fully opened, it creates a continuous living space between inside and outside.

Before you buy, there are a few things to consider so your new bifold doors work well and look great:

Aluminum is a favorite for its clean lines and weather resistance. Wood adds character but needs more care. Composite materials offer a balance between looks and strength.

Look for double- or triple-glazed glass to help with insulation. You can also choose tinted or low-E glass to reduce glare and block heat.

Depending on how wide your opening is, you’ll need to decide how many panels to use—and which side they’ll stack on when open.

Want a smooth transition from indoors to outdoors? A low or flush threshold helps prevent tripping and keeps the floor even.

These doors are designed to be easy to care for, but regular maintenance keeps them looking good and working smoothly.

• Clean the glass and frames with mild soap and water
  
• Wipe down the tracks and check for debris
  
• Lubricate hinges and moving parts once or twice a year
  
• Check for gaps or drafts, especially after storms
  

A quick check every season can help your bifold doors last for many years.

Are bifold doors energy efficient?
Yes—especially with double- or triple-glazed glass. Modern bifold systems are designed to keep heat in during winter and out in summer.

Can I use them for security?
Absolutely. Look for systems with multi-point locking, toughened glass, and strong frames. Many options are as secure as regular doors.

Do bifold doors work in small homes?
Yes. Even in smaller spaces, a three-panel system can create a wide opening and make the room feel bigger and brighter.

How much do they cost?
Prices vary based on size, material, and glass type. On average, you can expect to pay more than for standard doors—but the value they add makes them a smart investment.

Can I get custom sizes?
Most companies offer custom-fit bifold doors to match your exact opening. Just make sure to work with a trusted installer or contractor.
