Note:

  1. The "T" and "R" ratings are for 4" & 7" thick wall panels respectively.
  2. 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.
  3. Reference the UL Fire Resistance Directory for specific system details and materials.
