Yes, wooden doors can be fire-rated. Fire-rated wooden doors are specially designed and constructed to withstand fire for a specified period, typically ranging from 20 minutes to 90 minutes or more, depending on the requirements of building codes and regulations.

These doors are made with fire-resistant materials such as solid wood or engineered wood cores, along with fire-retardant coatings or treatments. Additionally, they may feature intumescent seals around the edges, which expand when exposed to heat to seal gaps and prevent the spread of flames and smoke.

Fire-rated wooden doors undergo rigorous testing to ensure they meet the necessary safety standards for fire resistance. They are commonly used in commercial buildings, hospitals, schools, and other public spaces where fire protection is essential.

It's important to consult with building code officials and fire safety experts to determine the appropriate fire rating required for wooden doors based on the specific needs and regulations of your building project.
