FS Pro & Sun Fire Defense: Understanding Modern Home Fire Protection Systems

10 min readFire Prevention

As California's wildfire seasons intensify and extend year-round, homeowners are seeking proven protection systems beyond traditional defensible space clearing. Two cutting-edge solutions—FS Pro and Sun Fire Defense—represent the next generation of home fire protection, using advanced chemistry to slow ignition and buy critical time during wildfire events.

What Are Fire-Retardant Coating Systems?

Fire-retardant coatings create a protective barrier on vulnerable surfaces, significantly reducing the likelihood of ignition from embers, radiant heat, and direct flame contact. Unlike basic paint or sealers, these specialized systems undergo rigorous fire testing and are formulated specifically for wildfire defense.

How They Work:

When exposed to high heat (300-500°F), fire-retardant coatings undergo a chemical reaction that creates an insulating foam layer. This layer:

  • • Reflects radiant heat away from the substrate
  • • Slows heat transfer to combustible materials beneath
  • • Releases water vapor that cools the surface
  • • Creates a char barrier that resists flame penetration
  • • Extends ignition time by 15-30+ minutes in laboratory testing

Critical distinction: These systems don't make homes "fireproof"—nothing can. But they dramatically increase survivability during the critical window when embers rain down and radiant heat builds, giving firefighters time to defend structures or allowing occupants additional evacuation time.

FS Pro: Transparent Fire Retardant System

FS Pro Fire Prevention System

Professional-grade transparent fire retardant for wood surfaces

FS Pro is a water-based, environmentally friendly fire retardant system designed specifically for protecting wood-based building materials from wildfire ignition. Its key advantage is transparency—it provides Class A fire resistance without altering the natural appearance of wood.

Sun Fire Defense: Fire-Blocking Coating System

Sun Fire Defense

Professional fire-blocking coating system for comprehensive protection

Sun Fire Defense is a specialized fire-blocking coating designed to create a protective barrier on roofs, siding, and other vulnerable surfaces. Unlike transparent retardants, this system creates a durable, pigmented coating that provides both fire protection and weather resistance.

Where Sun Fire Defense Is Applied

Roofing Systems

Primary application for maximum protection:

  • • Composition shingles
  • • Asphalt roofing
  • • Cedar shakes and shingles
  • • Metal roofing (prep-dependent)
  • • Roof edges and valleys

Exterior Walls & Siding

Critical protection zones:

  • • Wood and composite siding
  • • Stucco and fiber cement (when specified)
  • • Eaves and overhangs
  • • Gable ends and dormers
  • • Areas near vegetation

High-Risk Features

Extra attention zones:

  • • Attached structures (decks, pergolas)
  • • Entry areas and porches
  • • Garage doors and trim
  • • Vent surrounds and penetrations
  • • Chimney chases and covers

Sun Fire Defense Key Benefits

  • Slows Ignition from Embers:

    Significantly reduces the risk of spot fires from windblown embers—the primary cause of structure loss during wildfires

  • Radiant Heat Resistance:

    Insulating properties protect underlying materials from heat exposure before flames arrive

  • Weather Durability:

    Formulated to withstand UV exposure, temperature extremes, and moisture—critical for long-term California climate performance

  • Low Maintenance:

    Once applied, requires minimal upkeep beyond periodic inspection and spot treatment if needed

  • Increases Critical Defense Time:

    Buys 15-30+ minutes for firefighter intervention or self-defense measures during active fire events

FS Pro vs. Sun Fire Defense: Which System Is Right for You?

Both systems provide proven fire protection, but they excel in different applications:

Choose FS Pro When:

  • ✓ You want to preserve natural wood appearance
  • ✓ Protecting wood decks, fencing, or trim
  • ✓ Interior attic/structural wood protection
  • ✓ Cedar shake roofs or wood siding
  • ✓ High-visibility architectural wood features
  • ✓ Budget allows for premium transparent system

Choose Sun Fire Defense When:

  • ✓ Primary concern is roof protection
  • ✓ Composition or asphalt shingle roofing
  • ✓ Need comprehensive exterior protection
  • ✓ Want combined fire + weather resistance
  • ✓ Protecting eaves, soffits, siding
  • ✓ Cost-effective whole-home solution

Best Practice: Combined System Approach

Many homeowners achieve optimal protection by using both systems strategically:

  • Sun Fire Defense on roofs, eaves, and primary siding
  • FS Pro on decks, fences, wood trim, and visible architectural elements
  • • Result: Maximum fire protection without sacrificing aesthetic appeal

Troy Construction Design can assess your property and recommend the optimal combination for your specific situation and budget.

Application Process & Timeline

Professional application is essential for both systems to achieve rated fire protection:

  1. 1

    Property Assessment (1-2 hours)

    Troy Construction Design inspects your property, identifies high-risk areas, measures surfaces, and provides detailed scope of work and cost estimate.

  2. 2

    Surface Preparation (1-3 days)

    Cleaning, pressure washing, minor repairs, and priming (if required). Proper prep is critical for adhesion and longevity.

  3. 3

    Application (2-5 days)

    Professional spray application in multiple coats to achieve manufacturer-specified mil thickness. Weather-dependent—requires dry conditions and moderate temperatures.

  4. 4

    Curing & Inspection (3-7 days)

    Allow proper cure time before exposure to weather. Final inspection ensures full coverage and proper thickness.

Typical Project Timeline:

  • Small home (1,200-1,800 sq ft): 5-7 days total
  • Medium home (1,800-2,500 sq ft): 7-10 days total
  • Large home (2,500+ sq ft): 10-14 days total
  • Best season: Spring/Fall (mild, dry weather)
  • Avoid: Mid-summer heat or winter rain/cold

Cost Considerations & ROI

Fire-retardant coating systems represent a significant investment, but one that pays dividends in safety, insurance savings, and property value:

Typical Cost Ranges

  • FS Pro (wood treatment): $2-$4/sq ft
  • Sun Fire Defense (roof/siding): $1.50-$3/sq ft
  • Average home (2,000 sq ft): $8,000-$18,000
  • Large home (3,500+ sq ft): $15,000-$35,000

*Costs vary by surface condition, accessibility, and application complexity

Return on Investment

  • Insurance discounts: 5-15% annually
  • Property value increase: 3-7% in high-risk zones
  • Avoided loss risk: $300K-$600K+ protection
  • Peace of mind: Priceless

Payback period: 8-12 years through insurance savings alone

Maintenance & Longevity

Both systems require minimal maintenance but benefit from periodic inspection:

  • Annual Inspection (Recommended)

    Check for coating degradation, especially on high-exposure areas (roof peaks, south-facing walls). Look for chalking, peeling, or thin spots.

  • 5-Year Touch-Up

    Most systems benefit from spot treatment on high-wear areas after 5 years. Full reapplication typically needed at 10-15 years.

  • Post-Storm Inspection

    After severe weather or nearby fire events, inspect for damage. UV exposure and extreme heat can accelerate degradation.

Why Act Before Fire Season

Don't Wait Until Fire Danger Is Imminent

  • Application requires 5-14 days — Not possible during red flag warnings
  • Contractor availability — Demand surges before fire season, causing delays
  • Weather windows — Need dry, moderate conditions for proper application
  • Material lead times — Popular systems may have 2-4 week supply delays
  • Curing time — Systems need 3-7 days to achieve full fire resistance

Bottom line: Schedule your fire protection upgrades in late winter or early spring, not when evacuation warnings are already being issued.
