What term describes walls that are located around the outside perimeter of a structure?

The term that describes walls located around the outside perimeter of a structure is "exterior walls." These walls form the outer boundary of a building and are crucial for protecting the interior from the elements, providing insulation, and contributing to the structural integrity of the building. Exterior walls not only serve as a barrier against weather conditions such as wind, rain, and temperature changes but also play a significant role in the overall aesthetic and architectural design of the structure.

Interior walls, on the other hand, are located within the building and primarily serve to divide space, while partition walls can be either temporary or permanent divisions that do not necessarily have the structural importance of exterior walls. Load-bearing walls are specific types of walls that support the weight of the structure above them, and while they can sometimes be exterior, the term "exterior walls" specifically emphasizes the location around the perimeter of the building rather than their function in supporting loads.
