FactoryRegistry lists 200 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced building batts, blankets, and rolls in thermal resistance (R) values R10.9 or less, mineral wool for thermal and acoustical envelope insulation (for insulating homes and commercial and industrial buildings), in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.
