"fire-rated wall"の定義と意味

What is a "fire-rated wall"?

A fire-rated wall is a wall specifically designed to resist the spread of fire for a certain period of time, helping to protect the occupants and contents of a building. These walls are constructed using fire-resistant materials, such as concrete, gypsum board, or masonry, and are tested to meet specific fire safety standards. Fire-rated walls are commonly used in commercial and residential buildings to create safe zones and prevent fire from moving between different areas. They can also provide additional time for evacuation in case of a fire, contributing to overall building safety and compliance with building codes.
