What type of door requires that the frame be installed before the drywall?

The type of door that requires the frame to be installed before the drywall is a pocket door. This is due to the unique construction and installation method of pocket doors. Pocket doors slide into a pocket within the wall, which means that the wall cavity needs to be clear and properly framed before the drywall is installed. Since the door vanishes into the wall when opened, it necessitates having the framing in place to create this pocket space before any finishing elements, like drywall, are added. This ensures that there is enough room for the door to operate smoothly without obstruction and that the wall can be finished seamlessly around it. Other door types, such as sliding, French, or panel doors, generally do not require such specific compatibility with the framing timeline relative to drywall installation.
