James Hardie siding compared in flame test

A sponsored rebuilding feature published online on May 31 used a side-by-side flame demonstration to compare three siding types — James Hardie siding, wood-based siding and vinyl siding — in coverage tied to families rebuilding after the Eaton Fire. The article was distributed as branded content by Brandpoint and appeared on local news and syndication sites including mykxlg.com and FinancialContent, where it was labeled “BPT.” The piece did not present independent laboratory results for the side-by-side demonstration shown in its image caption. The most specific description available online was the caption itself, which said samples of James Hardie siding, wood-based siding and vinyl siding were “simultaneously exposed to direct flame until failure.” (markets.financialcontent.com) ### What exactly did the sponsored article show? The May 31 article framed the comparison around wildfire rebuilding in Altadena after the January 2025 Eaton Fire. It said the fire damaged or destroyed thousands of structures and described homeowners weighing durability and material choices as they rebuild. Brandpoint’s distributed version identified the siding types by name but did not publish a test protocol, burn duration, ignition source, temperature, sample dimensions or third-party certification for the pictured comparison. (markets.financialcontent.com) The online versions reviewed also did not include a named independent lab or a standards body tied to that specific demonstration. ### Was this an independent fire test or a marketing demonstration? The article was presented as sponsored content, not as an independent product test or a lab report. The “BPT” label and syndicated placement indicate a branded-content distribution format rather than a peer-reviewed or regulator-issued document. (markets.financialcontent.com) That distinction matters because ASTM and code-compliance claims are normally tied to named tests, formal methods and certification documents. In the Eaton Fire feature, those details were not attached to the side-by-side flame image or to the article text available online. ### What fire-test data does James Hardie publish separately? (markets.financialcontent.com) James Hardie’s own product pages say its siding complies with ASTM E136 as a noncombustible cladding, and the company says some fiber-cement products are noncombustible and-or have a Class A fire rating when tested under ASTM E84. The company also says fire resistance does not extend to applied paints or coatings, which may char or be damaged by flames. (markets.financialcontent.com) An ICC Evaluation Service report for James Hardie Building Products says the company’s fiber-cement panels, lap siding and cladding shingles have a flame-spread index of 0 and smoke-developed index below 5 under ASTM E84, and are classified as noncombustible under ASTM E136. That report is a separate code-compliance document and not the same thing as the sponsored side-by-side demonstration. (jameshardie.com) ### What does the Eaton Fire have to do with the pitch? Los Angeles County’s recovery site lists rebuilding resources for the 2025 Eaton Fire, including Altadena-specific information and resilient rebuilding guidance. Recent local coverage has also described the pace of recovery and the push for more rebuilding support in communities affected by the fire. The sponsored article used that rebuilding context to position siding choice as part of post-fire construction decisions. (cdn-v2.icc-es.org) The article itself tied the comparison to families rebuilding after the Eaton Fire rather than to a new regulatory action, a recall or a fresh building-code change. ### What should readers look for next if they want harder evidence? (recovery.lacounty.gov) ASTM test references, ICC-ES evaluation reports and local building-code requirements are the next documents to check if readers want to verify fire-performance claims beyond a marketing demonstration. James Hardie’s published materials already point to ASTM E84 and ASTM E136, while Los Angeles County’s Eaton Fire recovery site links residents to rebuilding and resilient-construction resources. (markets.financialcontent.com) As of June 1, the online Eaton Fire feature remained available in syndicated form, with the three named siding types and the direct-flame caption still visible. No separate independent lab certification for that specific side-by-side demonstration was cited in the versions reviewed. (markets.financialcontent.com) (cdn-v2.icc-es.org)
