What are fire-rated assemblies?
The ratings relate to fire tests designed to determine how quickly fire can raise the temperature to unacceptable levels. Fire-rated assemblies are tested and certified in their entirety.
How do you calculate fire protection rating for wood framing?
Fire protection rating is calculated from the flame side of the assembly and of course some assemblies have multiple flame sides. Your wood framing members are required to be not more than 16″ on center. When they are you get 20 minutes in a wall and 10 minutes with floor and roof joists.
