Fire resistance ratings are expressed in the number of minutes or hours a structure can withstand a fire simulation test.
Penetrations penetrations through fire walls such as for pipes and cables must be.
Nevertheless brick is commonly cited as among the best building materials for fire protection.
Expansion joints allow the material to expand to withstand the fire s heat.
According to the engineered wood association a one hour rating indicates that a wall constructed in a manner similar to the one tested will contain flames and high temperatures and support its full load for at least one hour after the fire begins.
