National Service Industries, Inc. (NSI) was a large American conglomerate whose industrial services divisions included asbestos-related products and insulation services. NSI’s Lightman Contractors subsidiary was among the significant asbestos insulation contracting companies operating in industrial and naval contexts during the peak asbestos exposure era. National Service Industries manufactured and distributed asbestos-containing products and provided industrial services that created asbestos exposure for workers at facilities and installations throughout the United States. Publicly filed asbestos litigation records document National Service Industries Corporation in multiple asbestos contexts: formal naming as a defendant in asbestos proceedings (with a documented motion to dismiss bearing NSI’s name), identification in the Heat & Frost Insulators asbestos worker framework, NSI alongside Owens Corning and other major asbestos product manufacturers, and formal asbestos litigation documentation naming NSI in product use contexts.

National Service Industries in Naval and Industrial Contexts
Insulation contracting services: NSI’s Lightman Contractors subsidiary provided asbestos insulation installation and removal services to industrial facilities, including naval installations and facilities serving the Navy supply chain. Lightman contractors performed the asbestos insulation work — including pipe covering, boiler insulation, and fitting cover installation — that created chronic asbestos exposure for insulation workers and surrounding trades.
Asbestos product distribution: National Service Industries served as a distributor of asbestos-containing industrial products, including insulation materials and specialty asbestos products used in industrial maintenance and construction contexts. NSI’s distribution network placed asbestos products at industrial and naval facilities throughout the country.
Industrial maintenance services: NSI’s industrial services operations included maintenance contracting at facilities where asbestos insulation was present — creating exposure for NSI workers who performed maintenance in asbestos-insulated spaces.
