About this detail

A non-rated pipe penetration through a floor or wall assembly accommodates both insulated and uninsulated piping configurations. A watertight grouted pipe sleeve is provided where required, extending one inch above the finished floor, with a minimum one-quarter inch annular space between the pipe and the drilled opening, sleeve, or core. Backup material and fire stopping material seal the penetration, while insulation is discontinued through the penetration and finished with a metal jacket as required. Escutcheons are installed at all exposed locations. Floor penetrations must be sealed, and similar construction is provided for wall penetrations.
