Firestop Services Toronto

Professional Firestop Services in the GTA

Konstruction Group provides professional firestop services as part of our complete insulation and drywall package for multiplexes and multi-unit residential buildings throughout Toronto. Whenever pipes, cables, or ducts penetrate fire-rated walls and floors, proper firestopping is required to maintain the fire resistance rating. We install tested firestop systems that meet Ontario Building Code requirements and pass fire marshal inspections.

Firestopping for Multiplexes

Duplexes, triplexes, and fourplexes require fire-rated separations between dwelling units. Every penetration through these fire barriers - plumbing pipes, electrical conduits, HVAC ducts, communication cables - must be properly firestopped to maintain the rated fire separation. We install firestop systems throughout multiplexes as part of our insulation and drywall scope.

Firestop Services

• Penetration Seals – Fire-rated sealants for pipes, cables, and conduits through fire-rated walls and floors
• Joint Systems – Fire-rated sealants for construction joints and gaps in fire barriers
• HVAC Penetrations – Firestop collars and wraps for ductwork through fire-rated assemblies
• Electrical Penetrations – Firestop putty and sealants for conduits and cable bundles
• Plumbing Penetrations – Firestop systems for water, drain, and vent pipes
• Documentation – Complete firestop installation records for inspections

Why Firestopping Matters

Fire-rated walls and floors only work when they're complete. Every unsealed penetration is a path for fire and smoke to spread between units. A 1-hour fire-rated wall with unfirestopped penetrations may fail in minutes. Proper firestopping maintains the rated protection for the full required duration, protecting occupants and meeting code requirements.

Tested Firestop Systems

We use firestop products from major manufacturers with tested and listed systems for specific penetration types. Each penetration configuration has an approved firestop method - we match the right product and installation to each situation. This ensures firestopping will perform as required during a fire event and pass inspection.

Part of Our Complete Package

Firestopping is included in our scope for multiplex projects where we provide framing, insulation, and drywall. We coordinate firestop installation after mechanical and electrical rough-in and before drywall. This works alongside our fire-rated drywall assemblies to provide complete fire separation. This integrated approach ensures all penetrations are identified and properly sealed - nothing gets missed between trades.
