Centennial Woods Fire-Performance Claims Audit
Audit date: 2026-08-27 UTC. Read-only: no edits, deletes, publishes, or external changes were made.
Executive summary
The live site repeatedly states that Flame Stop II “provides” Centennial Woods products with a “Class A Fire Rating.” This wording appears in the purchasable add-on data on 20 products, PDPs, contractor/exterior pages, fireplace and patio content, a fireproofing article, templates, product JSON, and Product JSON-LD.
The supplied test background does not support that breadth. ASTM reports apply only to the specimens tested and do not establish certification, listing, labeling, ongoing manufacturing inspection, finished-production equivalence, code compliance, exterior/WUI suitability, or safe heat-source clearances. No public DRI-One, ASTM E84, ASTM E2768, FSI/SDI, WUI, ignition-resistant, listed, or labeled claim/report was found in the accessible sources. That absence is positive; the unqualified Class A copy remains the material risk.
Audit evidence and limits
- Shopify Admin: 54 products, 25 collections, 57 pages, 86 articles.
- Published theme: Centennial Woods Live MAIN, theme ID 161720303857; 765 files read across all pages; processing=false.
- Public crawl: sitemap plus direct reads of all Admin product, collection, and page handles; product JSON endpoints; visible text, metadata, image alt/title, linked PDFs, and JSON-LD.
- Local PDF/collateral scan: no target fire-performance terms or ASTM report found.
- Google Drive, email, proposal, marketplace, and authenticated dealer systems were not connected; those require a separate access-enabled pass.

Negative findings
No accessible hit for DRI-One, ASTM E84, ASTM E2768, WUI, ignition resistant, or FSI/SDI was found. No ASTM or DRI-One report was found in accessible local PDFs. No direct fire-rating text was found in audited public image alt/title attributes. The fireproof article’s infographic alt text should still be visually reviewed. GREENGUARD/FSC “certified” references are environmental/indoor-air claims, not fire certification.
Immediate checkout and sales-flow corrections
- Replace the add-on wording in custom_fields.add_ons across all 20 products.
- Add limitations at the treatment selector and document the chemical/service/specimen/production distinction.
- Review the four Flame Stop II SKU bodies and quantity labels.
- Verify PDP HTML, cart, product JSON, Product JSON-LD, product feeds, and marketplace exports after source correction.
- Remove treatment-as-safety language for fireplaces, stoves, grills, fire pits, chimineas, high-temperature areas, and “safety codes.”
- Add combustible-material/clearance warnings to fireplace, mantel, and surround content.
- Hold Class A, A-rated, fireproof, prevents fire damage, WUI, ignition resistant, and code-compliant language pending approval.
Management/legal/technical review
Approve or reject: any Class A wording and its exact profile/finish/thickness boundary; Flame Stop II vs DRI-One naming; publication of any E84 result and exact specimen/test limitations; disclosure of the E2768 failure if E84 is referenced; any production inspection/listing/labeling evidence; exterior/WUI/ignition/decking/siding/fireplace/stove/grill/fire-pit/chiminea suitability; combined “certified/safe/commercial” impressions; and external dealer corrections.
External correction list
Material Bank is the identified Centennial-branded distributor/specifier correction. Reseller pages for Material Warehouse, RDR Technologies, and Value Building Supply need management/legal review where Centennial is named or linked. Authenticated marketplace/dealer inventory remains open because those systems were not connected.
Post-publish verification
- Re-crawl all 20 PDPs, treatment SKUs, contractor/siding/lumber/fireplace/patio pages, blogs, FAQs, and resources.
- Check visible copy, titles, meta descriptions, Open Graph, JSON-LD, image alt/captions, PDFs, feeds, cart, checkout-adjacent text, and search snippets.
- Confirm no unsupported rating, listing, label, certification, WUI, ignition, exterior-fire, clearance, or code claim remains.
- For any retained ASTM reference, identify exact specimen, thickness, finish, substrate/self-supporting condition, FSI/SDI, report date/lab, and limitations; state it is not certification, listing, labeling, or code approval.
- Search quote/proposal/order-confirmation/sales-email/presentation/internal-script systems once access is available.
- Record URLs, source fields, exact before/after copy, duplicate count, timestamp, and fresh public read-back.
