The primary purpose of firestopping materials in a building is to prevent the spread of fire and smoke between wall cavities. Firestopping involves the use of specific materials and techniques to seal openings and joints in walls, floors, and ceilings, which can serve as conduits for fire and smoke to travel through a building. By properly installing firestopping materials, it helps to contain a fire to its originating area for a longer period, allowing for safer evacuation and more time for emergency responders to arrive and mitigate the situation.

This function is critical not only for protecting property but also for ensuring the safety of occupants. Firestopping materials are designed to expand when exposed to high heat, effectively sealing gaps and preventing flames and smoke from moving into unburned areas. Therefore, they play a crucial role in fire protection strategies within the structure of a building.

The other options, while they may address important aspects of building construction, do not encompass the specific fire protection function that firestopping materials are designed to provide. For instance, enhancing energy efficiency and improving insulation relate more to thermal performance, and creating sound barriers focuses on noise reduction rather than fire prevention.
