6 Types of Sliding Doors


Sliding doors can be a practical choice, when the space for a hinged door is restricted, but they are also increasingly popular as a stylistic addition to the home.

The various types of sliding doors can offer flexibility in how you use and enjoy your living areas, encouraging a flow between rooms or from inside to outside.

Some sliding doors are suspended from a track, while others are mounted on a track at both the top and bottom.

In some configurations, a moving panel slides behind a fixed panel to open, or the door can slide along the adjacent wall.

Space-saving pocket doors slide into a wall cavity when open.

Sliding doors come in single or double configurations, or as multiple combined units for wider openings.

There are many different types of sliding doors on offer, in a wide range of materials, styles and configurations, so it’s important to think about what you want to achieve with your new doors, and the specifications of your space.

How Sliding Doors Enhance Your Space

Sliding doors can maximise your living area as they don’t take up extra floor space when open – unlike a hinged door that swings open into the room.

They are a great way of creating flow between rooms, and even connecting your inside and outside areas.

Internal sliding doors can give you great flexibility in terms of how much of an open plan feel you want between living areas, and many sliding door styles can become a design feature in their own right.

External sliding doors are a great way of opening up your internal living or dining area onto your outside space, such as a patio or decking.

Get to know the sliding door types on offer, and the pros and cons of each, so that you can make the right choice for your home.

Internal Sliding Doors

An internal sliding door can be a highly practical choice, for example in tight spaces such as a pantry or en suite bathroom, and they are popular for closets or wardrobes as they don’t take up floor space when open.

If you choose sliding doors with a distinctive style, such as solid timber barn doors, they can become an eye-catching design feature, as well as a functional solution.

Sliding barn doors between your living and dining areas, or as a majestic entrance to the master bedroom, can be an intentional style statement.

Sliding glass doors can enhance the flow of light around your home, while allowing you to close off certain spaces to reduce noise and heat transference.

Sliding or stacking room dividers can be used to separate a large open plan living area into usable zones when it suits you, giving flexibility for the whole family.

Internal Sliding Glass Doors

Internal sliding glass doors are a great way of keeping your rooms connected, and encouraging light flow between spaces, while still enjoying the privacy of different living areas.

For a home office, for example, sliding glass doors help to keep the room feeling light and airy, and connected to the rest of the home, while maintaining privacy, peace and quiet.

Pocket Door

A pocket or cavity wall door is usually a single sliding panel that slots into a hollow cavity in the wall when open.

These types of sliding doors are particularly suited to small bathrooms, laundries or pantries as they don’t take up any additional space and the door is almost invisible when open.

Even if you know how to install sliding doors, you may need the help of a professional to create your wall cavity and install a pocket door.

Sliding patio doors, or al fresco doors that lead out onto a verandah or decking area, help to bring the outside in – even when closed.

Large glass doors flood your internal living area with natural light and give you uplifting views of your garden or outside space.

When you want to let in the breeze and create a flow between inside and out, you can open up your doors and expand your living and socialising areas.

Large glass panels let in plenty of light and give you the benefit of the view when closed, with the option to open up your home and create a flow from inside to out.

They are ideal for expanding your living, dining and socialising space and creating a seamless flow between the interior and exterior of your home.

Al fresco doors consist of multiple panels that each slide on their own track.

The panels then slide horizontally and stack on top of each other when open.
