Firestopping & Safety Compliance
UL-listed firestop installation and inspection for every cable penetration — maintaining fire barriers and keeping your building code-compliant.
Overview
Every cable that passes through a fire-rated wall or floor creates a penetration that must be sealed with a UL-listed firestop system. Missing or deteriorated firestops are a serious life-safety hazard and building code violation. Summit DNC installs and inspects firestop systems for cable penetrations using Hilti, 3M, and STI products. We maintain documentation with photos and UL system numbers for every penetration — satisfying fire marshal inspections and insurance requirements.
Key Benefits
- Protect occupant life safety in fire events
- Pass fire marshal and insurance inspections
- Maintain fire-rated barriers as building code requires
- Documented firestop records simplify future additions
- Cable transit systems allow re-entry without re-sealing
- Reduced liability from code-compliant installations
