Insulation Thermal Barrier Materials Keyword Candidate Study

Filter-difference study

Against the 60-record Thermal Insulation Refractory Materials Keyword Candidate Study, this 48-record cohort shares 43 records. Only 5 occur here and 17 only in the reference; the union contains 65. These are filter-membership differences, not company entries or exits.

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

The largest recorded sub-industry participation gap is for Refractory and thermal-insulation materials: 31/48 here versus 31/60 in the reference, an absolute difference of 12.9 percentage points. The cohorts have overlapping company IDs and are not independent samples.

Zero means no recorded label, not no business; multi-label cells overlap.

Multi-label counts can overlap; filter compliance is not industrial advantage.

Existing excerpts do not certify entire old reports; list linkage is not final recognition. Full definitions are on the series page.

Fields can overlap; hits establish search relevance only.

Traditional materials require product and manufacturing checks

The Building materials label covers 1 records (2.1% of this cohort). This archive clue raises a verification question about Defined building products or production equipment with quality documents; it does not establish that these companies already deliver it.

Shared records with Aerogel Insulation Materials Keyword Candidate Study: 42; records in this cohort but outside that set: 6. The intersection/union ratio is 87.5%, a measure of label overlap rather than business collaboration. Read comparison
