In addition to the type and density of wood, the construction of the door plays a significant role in its fire resistance. Solid wood doors should be constructed without gaps or voids that could allow fire to spread more easily. The joints between the wood pieces should be tight and well-sealed to prevent the ingress of fire and smoke.

Fire safety codes may also require solid wood doors to be treated with fire-resistant coatings or sealants. These treatments can enhance the door's ability to withstand high temperatures and prevent the spread of fire. The specific type and application of these treatments will depend on the code requirements and the intended use of the door.

In conclusion, solid wood doors must meet stringent material specifications to comply with fire safety codes. These specifications ensure that the doors can effectively resist fire and provide a safe barrier for occupants to evacuate. By understanding and adhering to these specifications, manufacturers and builders can create solid wood doors that are both aesthetically pleasing and fire-resistant.
