Manufacturer & trust research
Johns-Manville
Johns-Manville was one of the best-known names in American insulation and building materials. This research page brings together remembered names and products, historical documents, New York connections and the Manville Trust to help investigate a possible asbestos exposure history.
Start with what you remember. A company name, product, package, job, building, coworker or approximate year can provide the first clue. The historical records below can help connect those memories to products and time periods, while official Manville Trust materials explain the current trust process.

Following a remembered exposure
From a name or product to historical evidence
Name / product→Workplace→Years→Work→Historical record
1. Start with the name
Write down the company, product, contractor or equipment name as it was remembered. Historical names and ownership can then be sorted out during the investigation.
2. Describe what you remember
A product name, package, color, texture, equipment, work area or material description can help narrow the historical search.
3. Add the place and years
Even approximate years and a remembered workplace can help distinguish between products, formulations, ownership periods and distribution histories.
4. Compare the memory with the record
Historical documents can then be used to investigate whether the remembered name, product, place and time fit together. Current trust documents separately govern trust procedures.
