Reply to "Fire Resistance Rating of a proposed design"

Hi, we have a meeting with our local building official on Monday AM.  We have decided to propose a variant on the WP 3820 that you directed us to.  Instead of the 1" gap in the generic design, we are substituting a 3/8" layer of gypsum and no gap.  Keeping the mineral insulation in place will be impractical without it.

Thanks again for your help.
