What type of doors are normally used as entrance doors?

Solid-core doors are typically used as entrance doors due to their construction and properties. They are designed to provide greater durability and strength compared to other types of doors. The solid core, made from a solid material like particleboard or plywood, offers better insulation, soundproofing, and security. This makes them ideal for external applications where weather resistance and protection against forced entry are concerns.

Additionally, solid-core doors have a more substantial feel and appearance, enhancing the aesthetic value of an entryway. Their weight and density contribute to both their durability and sound attenuation, making them suitable for residential and commercial entrance needs.

In contrast, hollow-core doors, while lighter and often less expensive, do not provide the same level of insulation or security, making them less desirable for entrance doors. Ledge doors are commonly used in barns and sheds and not typically for residential access. Panel doors, while they can be solid-core, usually feature a design that includes raised or flat panels that might lead to variations in strength and performance compared to solid-core doors. Therefore, solid-core doors stand out as the most appropriate choice for entrance applications.
