J-M pipe and boiler insulation: catalog no. 100.
A 1908 trade catalogue issued by the H. W. Johns-Manville Co. to present its pipe and boiler insulation products to builders and engineers. The plates show insulating block materials as photographed objects on soft grey grounds, alongside technical drawings of pipe joints, fittings and installed pipe runs. A designer could take the restrained tonal lighting of the block studies and the clean, labelled line diagrams of industrial pipework as models for technical product presentation.
