A panel door is a type of door that features a frame with one or more panels set within it. These panels can be flat or raised, and they are typically made from wood, although other materials like fiberglass or metal can also be used. The design allows for a variety of styles, making panel doors popular in both traditional and modern architecture. Panel doors are often used in residential and commercial buildings due to their durability and aesthetic appeal. They can be found in various sizes and configurations, including single or double doors. The construction of a panel door provides strength and stability, making it a reliable choice for entryways and interior spaces.
