What does a solid-core door consist of?

A solid-core door consists of wood core blocks inside, which provide substantial weight and durability compared to hollow-core doors. The core blocks are typically made from compressed wood fibers or solid wood pieces that are tightly packed together, giving the door its thick and robust structure. This construction enhances the door's insulating properties, soundproofing capabilities, and resistance to wear and damage. Solid-core doors are often used in places where privacy, security, or sound control is a priority, such as in bedrooms or offices. The wood core not only contributes to these features but also allows for a more solid feel when the door is used, making it a favored choice in various building applications.
