FireStorm EmberMesh roll This is a retrofit component this site records. It is not, by itself, an adopted-code approval.
Attribute match · limited evidence. Documented attributes match 9 published requirements — no listing program applies. Verify with your authority having jurisdiction or ARC. Limited evidence: a single positive channel so far — more programs or documentation may still move this record.

Status derived from the cited listings by a published rule, never hand-assigned. Each chip
above is one evidence channel and its direction. A listing is not a permit — the authority
having jurisdiction decides.

Documented attributes Each value below points to its field-level manufacturer, official-listing, test-report, or standard-body evidence.
Published requirement matches These links are generated from the cited attributes above. They do not decide installation or a project result.
Loose mesh is not the same object as a listed vent assembly. The manufacturer limits some test statements to vertical installation; confirm orientation, net free area, edge sealing, and the exact opening with the AHJ. Can I use this here
This trace joins product evidence to a sourced code application, then keeps every boundary,
map, date, project check, documented constraint match, and still-undocumented field visible.
It is not a permit result.
