What are the three main types of doors in construction?

The three main types of doors in construction are categorized into panel, flush, and specialty doors.

Panel doors are characterized by their design, which usually features a frame with panels inset. This construction provides both aesthetic appeal and structural integrity, making them a popular choice for entrances and high-traffic areas. Flush doors are flat and have a smooth surface, typically used in interior applications where a simple, minimalistic design is desired. They are often constructed from plywood, hardboard, or other materials that can be easily painted or finished. Specialty doors encompass a wide range of unique or custom designs, including fire-rated, sound-rated, or security doors, tailored for specific functions or environments.

This classification focuses on the physical structure and design purpose of the doors rather than their material composition or location in a building. Understanding these types helps in selecting the appropriate door for a given application, ensuring both functionality and design requirements are met.
