Product Description

Marinite — manufactured by United States Gypsum Company (USG) — was through the 1940s-1980 the U.S. Navy and commercial marine standard asbestos marine insulation board, bulkhead lining, and fireproofing board. Marinite was specified across U.S. Navy ship classes for engine-room bulkhead linings, machinery-space overhead and bulkhead fireproofing, joiner-bulkhead lining in crew berthing and mess spaces, and as the standard interior fireproofing board across Navy and Coast Guard vessels through the asbestos era.

Marinite was supplied in sheet form (typically 4×8 ft panels in varying thicknesses) and was routinely cut, drilled, scribed, and fitted to confined shipboard geometry by shipyard joiners, insulators, and Navy hull technicians during new construction, overhaul, and damage repair.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Marinite contained chrysotile and amphibole asbestos in its rigid binder system and that workers who cut, drilled, sanded, or removed Marinite — particularly in confined shipboard spaces with limited ventilation — released substantial respirable asbestos fiber loads.

United States Gypsum Company (Marinite) has been named as a Manufacturer Defendant in publicly filed U.S. asbestos personal-injury and wrongful-death litigation.

If You Worked With Marinite Marine Insulation Board

If you cut, installed, repaired, or removed Marinite or USG marine insulation board during the asbestos era — including aboard a U.S. Navy ship, commercial vessel, or in a U.S. shipyard — and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related illness, you may have legal rights.
