failure that occurs when an adhesive, sealant, or coating is ruptured

a restricting device composed of sheet metal and intumescent material that is used in conjunction with plastic pipes.

centered; the penetration materials are centered in the opening

a joint that acts to regulate the location and degree of cracking or separation resulting from the dimensional change of different elements within a structure

Chlorinated Polyvinyl Chloride Pipe - a type of pipe usually used for hot/cold water distribution, sprinkler piping, and some chemicals.

in sealants, the process by which a compound attains its intended properties through evaporation, chemical reaction, heat, radiation, or a combination

a technical drawing that includes instructions for installing systems

off center; the penetration materials are not centered in the opening

the ability of a material to return to its original shape

a material that rapidly returns to its original state after substantial deformation

a process or change that takes place with absorption of heat and requires high temperature for initiation and maintenance

a structural separation between building elements that allows movement without damaging the structure

a firestop meets the requirements for an F rating when it remains in the opening during without allowing the passage of flame, or the occurence of flaming on any element of the unexposed side of the firestop.

the property of a material or assembly to withstand fire or give protection from it.

a through-penetration firestop is a specific construction consisting of all materials that fill the opening around penetrating items such as cables, cable trays, conduits, ducts, and pipes and their means of support through the wall or floor to prevent the spread of fire. (ASTM)

a material that when exposed to heat, expands to fill a void in the penetration caused by the deformation or combustion of the penetrating item.

the space or opening between adjoining surfaces

denotes the amount of air leakage (cubic feet per minute) through a penetration

a noncombustible insulation material - sometimes referred to as mineral wool or safing

Material Safety Data Sheet - describes the properties, health effects, hazards, handling, and disposal of a material

the space in building construction through which penetrants (pipes, conduits, cables, etc) pass

Polyvinyl Chloride Pipe - a common plastic pipe used to distribute cold water; it melts quickly when exposed to heat or flame

a material that adheres to form a complete seal

a seal that prevents the passage of smoke and gases

a number assigned to a specific detail

indicates the amount of time (usually hours) it takes the temperature on the non-fire side of a fire-rated assembly to exceed 325°F above ambient (initial)temperature

a hole, void, or penetrating item through a wall or floor construction
