Metalclad Insulation Company (later Metalclad Insulation LLC) was a West Coast asbestos insulation contractor that supplied and installed asbestos insulation materials at United States Navy shipyards and aboard Navy vessels throughout the mid-twentieth century. Metalclad operated as a specialty insulation contractor — similar to Thorpe Insulation Company — bringing asbestos pipe covering, asbestos insulating cement (asbestos mud), and related materials into Navy shipyards and installing them throughout ships under construction and overhaul. The United States Navy was documented as a direct customer of Metalclad Insulation. Metalclad’s Navy shipyard work is specifically documented at Long Beach Naval Shipyard and at Lockheed Shipbuilding in the Los Angeles harbor area. Publicly filed asbestos litigation records document Metalclad Insulation Company as a formal asbestos defendant (Metalclad Insulation LLC), with Navy direct-customer documentation, Long Beach Naval Shipyard and Lockheed Shipbuilding presence, asbestos mud powder documentation, and personal testimony from workers who performed insulation work at West Coast naval facilities.
