Head Flashings Head flashings are used to direct water away from openings such as windows and doors. Flashing Penetrations Flanged penetration covers can be readily integrated into a drainage plane. Top edge of adhesive membrane is taped to drainage plane with sheathing tape. Alternatively, a cap flashing can be regletted into the foam sheathing with tape forming a transition to the cap flashing.

For example, when a firestop system protecting a plumbing pipe penetrates the gypsum membrane on one side of a fire-resistance-rated gypsum wall, this revised standard would be used to evaluate that firestop system.
Penetration Firestop System A through-penetration firestop or a membrane-penetration firestop. Membrane-Penetration Firestop System An assemblage consisting of a fire-resistance-rated floor-ceiling, roof-ceiling or wall assembly, one or more penetrating items installed into or passing through the breach in one side of the assembly and the materials or devices, or both, installed to resist the spread of fire into the assembly for a prescribed period of time.
Through-Penetration Firestop System An assemblage consisting of a fire-resistance-rated floor, floor-ceiling or wall assembly, one or more penetrating items passing through the breaches in both sides of the assembly and the materials or devices, or both, installed to resist the spread of fire through the assembly for a prescribed period of time.

The various types of membrane-penetrations identified in the building code are box type penetrations outlet boxes, gang boxes, hose cabinets, etc. Therefore, the firestop systems protecting penetrations within these assemblies need to maintain a similar level of performance.
Failure of the firestop system to maintain a similar level of performance may compromise the fire rating of the assembly. Unlike a through-penetration firestop system that penetrates entirely through the fire-resistance rated assembly, and as such can be seen from either penetratikn of the assembly, a membrane penetration firestop system may not be seen from the non-breached side of the assembly.

A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.
