In my condo (three floor building) the interior walls are all Fireguard-grade 5/8 drywall attached to 11 gauge structural steel studs (which SUCK except for when hurricanes blow through). Each original penetration has a fireguard “box” around it. I’m wondering if this is necessary? The construction is party wall, so there are four sheets of Fireguard between my interior and my neighbors. I’m told my interior wall is required to be 1hr firewall.
