What is Fire Rating?

The term "fire rating" designates the ability of a constructed assembly to contain a fire in a carefully controlled test setting for a specified period of time. The degree that assemblies retard the spread of damaging heat is measured in intervals of time. For example, if a construction assembly in the controlled test setting adequately contains the heat for two hours and meets other requirements during the laboratory fire test, it is given a two-hour fire rating.

We construct our Fire Rated Buildings using a double wall construction, 3/4" gypsum paneling, and R-11 Insulation. See diagram below:




FIRE RATING REQUIREMENTS
