A glass bifold door is a type of patio door. Unlike a sliding patio door, a glass bifold door folds in upon itself when open, like an accordion. 

A glass bifold door is favored by some homeowners because it saves space in the interior of the home. Plus, its engineering gives it a unique look that many homeowners prize.

On today’s market, it’s not uncommon to find four- or five-panel glass bifold doors. In fact, some glass bifold doors are classified as “moving glass walls.”
