A Business Owner’s Guide to Passive Fire Protection

Protec helps you protect your people, your property, and your operations with fireproofing and firestopping services.  

When it comes to fire safety, most businesses think about alarms, sprinklers, and extinguishers. These are active fire protection systems that kick in once a fire has already started, but your passive fire protection system is just as critical. You need built-in safeguards like fire-rated walls, sealed penetrations, and structural protection that slow a fire’s spread and protect key assets.  

Two essential components of your passive fire protection system are fireproofing and firestopping. Here’s a look at what each service does, how they work together, and what business owners should consider when evaluating their fire protection strategy. 

What’s the Difference Between Fireproofing and Firestopping? 

While the terms are often confused or used interchangeably, they serve very different purposes. Here’s a quick breakdown:

• Think of firestopping as plugging the holes in your fire-rated walls. 
• Think of fireproofing as shielding your structure from collapsing under extreme heat. 

Both systems are code-required and complementary. You don’t choose one over the other. 

Why Passive Fire Protection Matters to Businesses 

A fire can do more than cause physical damage, it can halt operations, void insurance, or even lead to loss of life. Fireproofing and firestopping are essential for businesses. 

• Life Safety: Slowing down the spread of fire allows more time for evacuation.
• Insurance and Compliance: Meeting building codes (like those in the National Building Code of Canada) is a legal requirement.
• Asset Protection: Compartmentalizing fire can limit damage to critical systems and valuable equipment. 
• Business Continuity: Protecting load-bearing structures prevents collapse, giving emergency responders a chance to act while minimizing downtime. 

Firestopping Seals the Gaps That Fire Exploits 

Modern buildings are filled with penetration routes, like pipes, wiring, or HVAC ducts, which can compromise your fire-rated walls and floors. That’s where firestopping comes in. 

How Firestopping Works

Firestop systems use materials like: 

• Intumescent sealants or silicone/urethane sealants 
• Composite sheets and wraps 
• Firestop bricks, pillows, and plugs 

These materials expand in the presence of heat, sealing off gaps and preventing flames and smoke from passing between rooms or floors. 

Common Firestopping Applications

• Between floors and walls (critical for multi-storey buildings)
• Around electrical or plumbing penetrations
• At head-of-wall joints and expansion gaps 

Fire Code Requirements

Canadian codes require routine inspections and maintenance of fire barriers. Any breach, whether it’s planned or accidental, must be resealed using approved systems. 

Fireproofing Gives Your Structure a Chance at Survival 

Fireproofing protects structural steel and other load-bearing elements from reaching failure temperatures in a fire. Without it, steel can begin to fail in under 10 minutes. 

How Fireproofing Works 

Protec installs two types of fireproofing: 

• Cementitious Fireproofing is a spray-applied, non-combustible mix that insulates structural steel. It’s cost-effective, durable, and ideal for industrial settings.
• Intumescent Coatings are paint-like materials that expand into insulating foam under heat. Best for architectural finishes or exposed steel. 

Our focus is on cementitious systems. They are long trusted for their affordability, fire resistance, and fast application, and are the backbone of most commercial and industrial fireproofing projects. 

Fireproofing vs. Firestopping Between Floors 

Multi-storey buildings pose a unique challenge: fire and smoke naturally rise. If penetrations aren’t sealed properly between floors, fire can climb rapidly. Firestopping between floors is a building’s primary defense against the damaging spread of fire. 

• Firestopping keeps fire from traveling through mechanical shafts or wall gaps. 
• Fireproofing ensures that the floor assembly (beams, decks) retains structural integrity. 

Both systems need to work in tandem for vertical fire protection in multi-storey structures. 

Cost Considerations for Passive Fire Protection 

When budgeting for passive fire protection, consider how it’s an investment in building safety, compliance, maintenance, and durability. Costs depend on: 

• Project Scope: Size, height, number of penetrations, and access
• System Type: Cementitious vs. intumescent fireproofing
• Building Phase: New build vs. retrofit (retrofits can be more complex)
• Coordination with Trades: Working around other systems increases labour time
• Inspection Requirements: High standards demand experienced applicators

Working with Protec for your passive fire protection needs can save you time and money. We streamline coordination and digital documentation on every project to reduce rework and meet inspection on the first pass.
