Through-Penetration Firestopping

Firestop systems for pipes, conduits, cables and other penetrants passing through rated walls and floors.

Firestop systems for pipes, conduits, cables and other penetrants passing through rated walls and floors.

Scope and Field Conditions

Through-Penetration Firestopping should be approached as a system condition rather than a generic material application. The wall or floor assembly, penetrant, opening geometry, movement, insulation and surrounding construction all influence how the condition should be coordinated.

Typical Scope

  • Penetration condition review
  • Approved system coordination
  • Installation around penetrants
  • Photo and location documentation

Our Project Workflow

We organize the work around pre-installation condition review, field sequencing, controlled installation, punch-list response and closeout documentation. This makes it easier for general contractors and trade partners to understand what has been completed and what still needs attention.

Documentation Matters

Where project requirements call for system references, location tracking, photographs or closeout packages, those records should be captured while the work is accessible. The NYC Firestop CMS includes dedicated content and lead workflows that support this documentation-first positioning.

Project note: Actual firestop conditions must be evaluated against the project documents and the applicable tested or approved system. This website content is not a substitute for project-specific engineering, inspection or code review.
