On a hotel project I managed, luggage carts kept scraping the walls until we switched to double doors. That one change fixed it.

Small adjustments like this can save time and money in day-to-day operations.

I have worked with villas, hotels, and B&Bs, helping owners select doors that handle constant use while keeping their spaces looking good.

In this guide, I will explain what a double door is, how it works, and why many businesses install them. By reading this, you will have a clear view of whether it fits your property.

What seems like a simple feature often becomes one of the most practical upgrades.

So, let’s get started!

1. What is a Double Door?

A double door is simply two doors side by side that open from the center. I have seen them used often in villas, hotels, and B&Bs because they create a wider entrance for people and equipment. You get more space to move things in and out without damaging walls or door frames.

When you look at it from a business angle, a double door is about function first. It makes daily operations smoother for your team and guests. If you’ve ever struggled with a single narrow door on a busy property, you already know why this setup matters.

2. Common Materials of Double Door

I often get asked, “Which material is best for a double door?” The answer depends on your property and how you plan to use the doors. Here are the seven most common materials I’ve worked with, along with where they make the most sense for you:

3. Types of Double Doors

Over the years, I’ve worked on many projects where the type of double door made a big difference. The right style depends on how your property is used and the impression you want to give. Let’s look at some of the most common types that businesses choose.

Swing Double Doors

This is the most common type and probably the one you picture first. Swing double doors open inward, outward, or both, depending on how they’re installed. They’re reliable and easy for guests or staff to use. For busy entrances like hotels or villas, this style works well because it’s familiar and straightforward.

Sliding Double Doors

Sliding double doors move along a track instead of swinging open. This design is ideal for areas where floor space is limited.

I know many villas, hotels, and greenhouses choose sliding glass doors to let in natural light and create a more open feel. For your property, they can improve access while saving valuable space.

Folding Double Doors

Also called bi-fold doors, these fold to the side instead of swinging or sliding. They’re useful for connecting indoor and outdoor areas, such as dining spaces or lounges.

Folding doors make it easy to open up a large section of a wall while still giving flexibility to close it when needed. If you manage a property where guests move between indoor and outdoor areas, this type is worth considering.

French Double Doors

French doors are known for their glass panes framed with wood, aluminum, or steel. They add light, visibility, and a touch of elegance. These doors are often installed in villas, B&Bs, and boutique hotels where design matters just as much as function. They work best where appearance and openness are a priority.

Pivot Double Doors

Pivot double doors rotate on a pivot hinge at the top and bottom rather than traditional side hinges. This design allows for larger, heavier doors that make a strong statement.

They’re often used in luxury villas or high-end hotels that want a bold entry feature. While less common, they provide a modern look that can set your property apart.

4. Design and Customization Options

I’ve been part of projects where the design of a double door changed the whole look of a property. With the right choices, you can balance function and style at the same time. Here are designs and customizations you might consider:

  • Glass Panels: Glass inserts bring in light and make spaces feel open. They’re often used in hotels and villas where appearance is as important as access.
  • Decorative Frames: Frames can be simple or ornate depending on the property. This choice lets you match the overall design theme, whether modern or traditional.
  • Hardware Finishes: Handles, locks, and hinges come in many finishes like brass, chrome, or matte black. These small details tie the doors to the rest of your design.
  • Color Choices: You can go with natural stains, painted tones, or even metallic coatings. The finish you pick helps the door either blend in or stand out. Vallisco provides a wide range of finishing options, so your double doors match both the look and function your property needs.
  • Panel Styles: Double doors can be solid, divided into panels, or mixed with glass. Different styles give you flexibility to fit both function and appearance.
  • Size Adjustments: Doors can be made wider or taller to match the space you’re working with. Custom sizing makes sure the door looks right and works smoothly.

5. Common Uses of Double Doors

Double doors serve many purposes across different types of properties. They go beyond appearance and directly affect how smoothly people and equipment move in and out. Here are some of the most common ways businesses use them:

Main Entrances

The most common use is at the main entrance of villas, hotels, and B&Bs. Double doors give a wider opening, which instantly creates a welcoming impression.

They also reduce crowding when guests or staff move in and out at the same time. I’ve noticed that properties using double doors here often look more professional to visitors. For you, this can be the difference between a cramped entry and one that feels open and organized.

Service and Staff Access

Hotels and greenhouses often rely on staff moving carts, tools, and supplies throughout the day. A single narrow door slows this process and can lead to unnecessary damage. Double doors give the clearance needed for smooth movement and reduce time wasted in daily operations.

This makes staff routines easier and protects your property from extra wear and tear.

Emergency Exits

Another important use is for emergency exits. Double doors allow people to leave quickly and safely when needed. The wide opening makes it possible for large groups to exit without bottlenecks. For businesses handling high traffic, this design improves both safety and compliance with local building standards.

Indoor Transitions

Double doors are not limited to outside access. They’re often used to connect large indoor spaces like lobbies, dining halls, or conference rooms. This creates a sense of flow while also making it easier to manage traffic during events or busy hours.

In hotels or villas, I’ve seen them add both function and style. For your property, they can improve movement inside while keeping the design consistent.

6. Installation Tips

Did you know that many door problems come from poor installation rather than the doors themselves? Getting the basics right from the start makes your double doors last longer and function better. Here are some tips I recommend keeping in mind:

Measure Accurately

Accurate measurement is the foundation of a smooth installation. I always remind teams that a small mistake here creates big issues later. Measure both the frame and the wall opening carefully, then double-check before ordering. This one step alone prevents costly adjustments.

Check Frame Strength

A strong frame is just as important as the doors themselves. Weak or uneven frames can make the doors sag or fail to close properly. In many projects, fixing the frame ended up costing more than the doors.

Reinforcing it upfront keeps everything aligned and secure.

Plan for the Swing or Slide

Think about how the doors will move once installed. Swing doors need clearance, while sliding doors require enough track length.

I know some businesses overlook this and end up blocking pathways. Planning early avoids daily headaches for staff and guests.

Secure the Hardware

Handles, locks, and hinges take heavy use every day. Low-grade hardware loosens quickly and creates maintenance issues. Commercial-grade fittings are designed to handle constant use and last longer. Reliable hardware makes day-to-day access easier for staff and guests.

7. Factors To Consider When Choosing Double Door

I’ve noticed that businesses sometimes choose doors based only on looks, and that usually leads to problems later. Here are three key factors you should think about before deciding:

Material and Durability

The type of material you choose will decide how long the doors last and how much upkeep they need. Steel and aluminum hold up well under heavy use, while wood adds character but may need more care.

I recommend thinking about how much traffic your property handles each day before making this choice. Picking the right material upfront saves you maintenance costs down the road. Vallisco offers a range of durable options designed for high-use properties, giving you doors that balance strength with style.

Function and Space Needs

How the doors move, whether they swing, slide, or fold, makes a big difference in how your space functions. A villa entrance with high guest traffic may benefit from swing doors, while a greenhouse might need sliding doors to save space.

Matching the door style to your daily operations will make life easier for you and y

Security and Safety

Doors are also part of your property’s safety plan. Strong locks, reliable frames, and compliance with fire codes are all things you cannot overlook. In hotels and B&Bs, double doors often act as emergency exits, so safety features become even more important.

Choosing the right hardware and installation method gives you peace of mind that both staff and guests are protected.

Conclusion

Double doors solved the issue of scratched walls and tight spaces in that hotel, and they can do the same for you.
