Armstrong Asbestos Cork pipe Insulation
Example of vintage, thick cork pipe insulation with a thin, black non-asbestos, bituminous tar-like outer coating and an asbestos-containing seam compound. The outer black coating is approx. 2-3mm thick, but did not test positive for asbestos. However, there is a black mastic compound applied along the sectional seams that did test positive for chrysotile asbestos.
This pipe fitting insulation, with manufacturer's name indentations indicates "Armstrong ; Brine", is shown partially damaged with a small section missing. The absent portion demonstrates the material's layers and how the pipe insulation is designed to surround the pipe. Also shown are original wire-bracings that keep the fitting insulation together on the pipe.
