Fire barrier walls are typically continuous from an exterior wall to an exterior wall, or from a floor below to a floor or roof above, or from one fire barrier wall to another fire barrier wall, having a fire resistance rating equal to or greater than the required rating for the application.
Building codes have special requirements for the walls separating adjacent townhome units, and the primary requirement is that they serve as two-hour firewalls–meaning that fire in one unit will require at least two hours before breaking through the wall.
A "one-hour" fire rating is given to an assembly consisting of various building materials that can resist the exposure of a standardized fire exposure for one hour.
Type X fire rated gypsum drywall is 5/8 -inch thick and installed on each side of a wood framed wall to create the fire separation. Type C fire rated drywall has more glass fiber reinforcement and other ingredients compared to type “X,” which make it superior to Type X. Type C gypsum board is available in 1/2-inch and 5/8-inch thicknesses.
Double the number of Type X sheets on the wall for a simple system installed over fire-resistant fiberglass insulation; each sheet of 5/8-inch Type X drywall is rated to resist fire for one hour, so two layers will produce a two-hour firewall.
