FenceTrac fire-rated fencing carries an ASTM E84-24 Class A rating with a Flame Spread Index of 0 and a Smoke Developed Index of 35, tested by QAI Laboratories. The difference between “fire-rated” and “fire-resistant” is the difference between a tested, documented classification and a vague marketing descriptor. When building codes or project specs require fire performance, only a fire-rated product with third-party test data will satisfy the requirement.
The Short Answer
“Fire-rated” means the material was tested to a recognized fire standard (typically ASTM E84) by an accredited lab and earned a specific classification. “Fire-resistant” has no standardized definition, no required test, and no classification tier. A product labeled “fire-resistant” may slow combustion to some degree, but there is no way to compare it to another product or verify its performance against a code requirement.
What Fire-Rated Actually Means
A fire-rated designation is backed by a specific test, a documented result, and a formal classification.
Third-Party Laboratory Testing
The material is tested by an accredited, independent laboratory under controlled conditions. The lab follows a published ASTM, UL, or NFPA test protocol. The results are documented in a formal test report with a report number, test date, and detailed findings.
FenceTrac’s fire-rated fencing was tested by QAI Laboratories under report QA-3344-R2, following the ASTM E84-24 protocol.
Documented Performance Numbers
The test produces specific, quantifiable results. For ASTM E84, those numbers are the Flame Spread Index and the Smoke Developed Index. FenceTrac’s results: Flame Spread Index of 0 and a Smoke Developed Index of 35.
These numbers are not estimates or ranges. They are measured values from a controlled test that any engineer, architect, or code official can verify against the published report.
Classification Tier
Based on the test results, the material receives a classification. ASTM E84 uses three tiers: Class A (FSI 0-25), Class B (FSI 26-75), and Class C (FSI 76-200). FenceTrac’s results place it in Class A, the highest tier.
What Fire-Resistant Actually Means
“Fire-resistant” is a descriptive term, not a classification. There is no ASTM standard that defines “fire-resistant.” There is no test protocol that awards this label. Any manufacturer can call any product “fire-resistant” without submitting it for testing.
Some materials marketed as fire-resistant may genuinely slow combustion. Pressure-treated wood, for example, can be treated with fire-retardant chemicals that delay ignition. But “delay” is not “prevent,” and without a test report, there is no way to know how the material performs under specific fire conditions or how it compares to an ASTM E84 Class A rated product.
Fire-retardant coatings and chemical treatments can also degrade over time with UV exposure, moisture, and weathering. A fire-rated material like aluminum does not rely on a coating for its fire performance. The non-combustible property is inherent to the material.
Why the Distinction Matters for Commercial and Code-Required Projects
Building codes do not accept “fire-resistant” as a qualification. When a code or specification calls for fire-rated fencing, it references a specific standard and classification.
Code Compliance
Building codes that require fire-rated fencing, including IBC Chapter 8, NFPA 101, and various wildland-urban interface codes, reference ASTM E84 Class A (or equivalent) as the minimum standard. A fence labeled “fire-resistant” without an ASTM E84 test report will not pass inspection in these jurisdictions.
Specification Language
Architects and specifiers who write “fire-resistant” into a bid spec are leaving the requirement open to interpretation. Writing “ASTM E84-24 Class A” closes the ambiguity and gives the general contractor a clear, verifiable benchmark. FenceTrac provides architect specifications and the full QAI test report to support this language.
Liability and Insurance
In fire-sensitive applications, the property owner and the specifying architect carry liability for material selection. A documented ASTM E84 Class A test report from an accredited laboratory provides a defensible record. A general “fire-resistant” claim from a product brochure does not.
Design Options for Fire-Rated Privacy Fencing
Fire-rated fencing does not have to look institutional. FenceTrac’s fire-rated system uses 6063-T5 aluminum infill inside the same galvanized steel frame used across the entire FenceTrac product line.
The aluminum infill is available in Black, White, Silver, and Bronze powder-coat finishes. The result is a full privacy fence that also carries a Class A fire rating, suitable for commercial properties, schools, healthcare facilities, and any project where both aesthetics and fire performance matter.
Related Questions
What does ASTM E84 Class A mean for fencing? ASTM E84 Class A means the material scored a Flame Spread Index of 0 to 25 and a Smoke Developed Index of 450 or less in laboratory testing. FenceTrac scored 0 and 35.
What is fire-rated fencing and when is it required? Fire-rated fencing is required near occupied structures, utility areas, and in wildland-urban interface zones where building codes mandate non-combustible or Class A rated barriers.
What materials qualify for fire-rated fence applications? Non-combustible metals like aluminum and steel qualify. Wood, vinyl, and standard composite materials do not meet ASTM E84 Class A thresholds.
