What are Bifold Doors?

Bifold doors have become a popular and practical solution for homeowners aiming to enhance the functionality and aesthetic appeal of their living spaces. Unlike traditional hinged or sliding doors, these designs offer a unique concertina-style opening that seamlessly integrates indoor and outdoor areas, flooding interiors with natural light and creating a seamless flow between spaces.

How Do They Work?

Bifold doors operate by panels that fold along a track system. Unlike standard swing doors or sliding doors, bifold doors utilise a concertina-like motion, allowing the panels to fold neatly into a compact stack at one or both sides of the opening. This mechanism is facilitated by a series of hinges and rollers. When you push or pull the door, the panels fold in pairs and glide smoothly along the track system to occupy less space.
