Which type of door is known for its ability to hold back fire effectively?

A solid core door is known for its ability to hold back fire effectively due to its construction and material composition. Unlike hollow core doors, which are lighter and typically made with a frame that has a hollow interior, solid core doors have a dense core that is often made from solid wood or composite materials. This dense construction provides better insulation and greater resistance to fire, as it takes a longer time for heat to penetrate through the solid material compared to hollow structures.

Solid core doors are designed to withstand fire for a specified duration, typically rated under fire safety codes, which enhances the safety of occupants in case of a fire emergency by delaying the spread of fire and smoke. When installed in buildings, especially in areas where fire resistance is crucial, such as between different compartments or leading to exits, solid core doors play a vital role in fire protection strategies.

The other door types, such as hollow core, panel, and sliding doors, do not have the same level of fire resistance. Hollow core doors, for example, are designed primarily for ease of use and cost-effectiveness rather than fire safety, and panel doors may vary in their construction and do not necessarily provide the same level of protection as solid core doors. Sliding doors also generally lack the mass and sealing properties
