Where: Table 3.37, roof tile row, p. 3-41
Publishes density 1900 kg m-3, thermal conductivity 0.84 W m-1 K-1 and specific heat 800 J kg-1 K-1.
Applies to: parameters.albedo, parameters.emissivity
Where: Table 3.40, purple/dark clay tile row, p. 3-45
Publishes absorptivity 0.81-0.82 and emissivity 0.85-0.95. The complementary albedo interval is 0.18-0.19; stored albedo 0.185 and emissivity 0.90 are within the intervals.

Stores the same tuple under MAPSECC Ref 90240069; the root spreadsheet contains the same row, excluding YAML migration as the cause of the attribution.
| Name | supported Guide A names roof tile, exactly matching the retained identity. |
|---|---|
| Target | supported The source tables and historical catalogue describe thermophysical and radiative material properties. |
| Values | supported Table 3.37 publishes the exact thermal tuple. Table 3.40 supports the stored radiative values either directly, by exact absorptivity complement or as a scalar within a published range. |
| Source | supported CIBSE Guide A is the source for the thermal tuple and radiative evidence. Canonical field-level metadata distinguishes direct publication, exact calculation and a retained scalar selected within a range. issue #866 |
| Place | not applicable The generic material row makes no observation-place claim. |
| Representativeness | not applicable The generic material row makes no site, city or regional evidence-reach claim. |
| Method | supported Literature is the record-level method for directly adopted values. Canonical overrides record the exceptional leaves as follows: albedo assumed within 0.18-0.19; emissivity assumed within 0.85-0.95. |
| Identity | supported Legacy ID 36248199 identifies the retained catalogue row; correcting its source and field-level method metadata does not change the stable path, values or material identity. |
This correction changes provenance metadata only. The source ranges and any absorptivity-to-albedo complement are explicit, so the active scalar is not presented as an exact printed value. The material is unlinked from any current construction record. The stable record path remains unchanged because paths are database identities, not citations.
