Note:
-
The “T” and “R” ratings are for 4″ & 7″ thick wall panels respectively.
-
Continuous insulation extends through the wall opening. Discontinuous insulation does not extend through the wall opening, but terminates against the wall face on both sides.
-
Reference the UL Fire Resistance Directory for specific system details and materials.
