Single Leaf Doors

As the name suggests, single leaf doors have a single door panel that opens. They are the most common type of door found in residential homes. Single leaf doors are also popular in commercial and industrial applications, particularly in smaller openings.

Examples of single leaf doors: Personal Access (PA) doors

Double Leaf Doors

While single leaf doors are made up of a single door leaf or panel that opens and closes, double doors have two panels that open in the middle, giving you a wider opening. These two panels are sometimes separated by a mullion.

Double doors may feature door leaves that are equal in width (called an equal pair) or different widths (called an unequal pair). Double leaf doors are common in larger commercial and industrial applications.

Advantages of single-leaf vs double-leaf door designs


One of the main advantages of single-leaf or single panel doors is that they are easier and cheaper to manufacture than double-leaf doors.


They are also generally lighter in weight, which makes them easier to install and operate.


Another advantage of single leaf doors is that they can be fitted with a variety of door hardware, including door closers, panic bars and electromagnetic locks.

Disadvantages of single-leaf doors over double-leaf doors


The main disadvantage of single-leaf doors is that they are limited in size. They are not suitable for large openings, as they cannot be made to span a large opening like a double leaf door can.

Which door is right for your business?


When deciding which type of door is right for you, it's important to consider the available space. A single-leaf door may be better if you have a smaller opening. If you have a larger opening, a double-leaf door will give you more space to work with.

Another thing to remember is that single-leaf doors are easier to install in smaller openings. Hiring a professional to install your door may be necessary if you have a larger opening.


Doors can also be used for a number of different reasons. They can be used for personal access — single-leaf door or for transporting products and equipment in and out of a building — double-leaf door. In this case, it’s best to weigh up how you’ll use this door in the future.

If you need a door for ventilation or light, a single-leaf door may be the better option, as it can be fitted with various hardware, including vents and windows.


When it comes to cost, single-leaf doors are generally cheaper than double-leaf doors.  However, this is not always the case, as the door's cost will also depend on the materials used and the size of the door.


If security is a key concern, a double-leaf door may be the better option. Both single-leaf and double-leaf doors can be equipped with security features, such as door closers, panic bars and electromagnetic locks.


When it comes to materials, both single-leaf and double-leaf doors can be made from a variety of materials, including wood, steel and aluminium. The type of material you choose will depend on the safety and building regulations in your industry, your budget and the look you are trying to achieve.

Function: Sliding or Swinging

Doors can either slide open or swing open. Sliding doors are more common in commercial applications, as they offer a wider opening. Swinging doors, on the other hand, are more common in residential applications. Single and double-leaf doors are available in both sliding and swinging styles.


Both single-leaf and double-leaf doors come in various styles, so you can choose the one that best suits your space. If you're looking for a door with a more traditional look, a single-leaf door may be the right choice. If you're looking for a door with a more modern look, a double-leaf door may be the right choice.

Doors can greatly impact the look and feel of your sheds, warehouses, or worksite, so it's important to consider aesthetics in your decision. A professional, high-quality door can give your business a polished look, while a cheap, flimsy door can make your business look unprofessional.
