What Are Bi-fold Doors?

Bi-fold doors are sometimes called concertina or folding doors, because they consist of interlocking doors that can slide and fold up together.

Internal bi-fold doors generally consist of two to six doors linked by a specialist hardware. This will enable the internal bi fold doors to fold and slide open and shut. 

The number of doors in your bi-fold internal door depends on the space of your opening. 

Why Choose Bi-fold Internal Doors? 

With folding internal doors, you can change your space from open plan to a smaller room that’s a little more snug – whenever you like. 

Just by simply pulling the internal folding doors shut, you can create a different look and feel to your home. 

Other benefits of internal folding doors

However, there are many other benefits to choosing interior folding doors. 

The easy switch from an open plan room to a smaller living space allows you to entertain in a bigger environment when you want to, but you can also shut the doors for privacy too. 

What Are The Environmental And Spatial Benefits Of Internal Folding Doors?

An internal bi-fold door is a way to have an extra wall in your house whenever you want it. 

By opening your bi-fold doors, you can let more natural light in throughout your house because you have fewer walls blocking the sunlight. 

But by closing the bi-fold internal doors, you can reduce your heating costs and limit noise transfer throughout your house. Small spaces have their advantages too!

Where Are The Best Places For Folding Internal Doors?

The most popular places for internal folding doors are as a room divider between the living room and the conservatory or between the dining room and the living room.

It is also possible to utilise a folding internal door between living areas and a smaller room to create rooms with distinct purposes, such as a home office or a children’s play room.
