The #1 Preffered Firestopping Contractor in the Tri-State Area  





  • Using a professional installer

    Typically, firestop system installation is left up to the individual trades that make the holes in the fire-rated construction. However, inspections show this can increase the likelihood of deficiencies that later need to be corrected. To help resolve this problem, construction teams increasingly are turning to the use of professional firestop installers/contractors.
    A professional firestop installer:

    • Has a better understanding of tested systems;
    • Allows individual trades to focus on their areas of expertise;
    • Helps ensure one-source continuity and system compatibility for all firestop applications;
    • Promotes hassle-free inspection by officials who know and trust professional firestop installers;
    • Provides single contractor accountability for all firestop applications;
    • Documents all installed firestops, depending on the agreed-to scope of work; and
    • Increases confidence that all firestopping is completed correctly the first time.

    Additionally, Fire Seal Corp. participates in manufacturer-sponsored and other industry-recognized accreditation programs that provide training on the correct—and safe—installation of firestop systems.

  • The Benefits of Using a Firestop Specialty Contractor.

    Firestopping through-penetrations and joints in fire-rated assemblies can be
    a complicated process. To do the job correctly and cost-effectively, it may be best
    to call on a specialty contractor that knows the building code requirements inside and
    out. Firestopping is a method of passive fire protection that helps contain fire and
    toxic gases to the area of origin by sealing around service penetrations or construction joints in fire-rated walls or floors.
    To help prevent the rapid spread of fire within a building, certain walls and floors
    are required to meet a specific fire resistance rating (i.e., the period of time during which a building component has been tested to confine or compartmentalize a fire, or continue to perform a structural function). Compartmentation limits the spread of fire, allows time for the fire to be extinguished, and provides evacuation paths for people in the building.
    The code-mandated fire resistance of walls and floors must be maintained,
    despite the fact gaps will be needed in those assemblies for joints and for building services such as water, power, data and ventilation. A properly selected and installed
    firestop system can restore the full fire resistance rating of the underlying assembly while providing the needed functionality of the joint or service penetration.

  • Choosing a Firestop system
    A firestop system is a tested combination of the substrate (wall or floor), penetrating item or items, opening size, annular space and materials used to seal or protect the opening. To evaluate compliance with building code requirements, systems typically are tested by independent third party test labs. Successfully passing the test means a firestop system is “listed” and the materials used in these systems generally are marked as “classified.”
    Several factors can affect the performance of a firestop system, all of which can be determined by examining the submitted system drawings. If a detail does not match the tested system requirements (e.g., pipe diameter and type, hole size, floor thickness, annular space), the installer must be able to find another tested system that matches the
    field application, or request and obtain a custom solution from the firestop material
    manufacturer. Finding appropriate systems can be somewhat daunting, as there are
    currently more than 7,000 tested systems for various applications.

    The International Building Code also prohibits the protection of penetrations
    and joints in fire resistance-rated assemblies from being concealed before being
    inspected and approved. Traditionally, building officials performed these inspections; however, there is a move toward third-party inspection. Two standard practices are now available for firestop inspection and reporting: ASTM E-2174 for through-penetrations
    and ASTM E-2393 for joints and perimeter fire barrier systems. These practices provide methods by which qualified inspectors can verify that all firestop system installation requirements on a project have been met and that their installations are in accordance with the inspection documents.
