Protective inner layer for high temperature insulations. For vibrating pipes and underground insulation--excellent efficiency. Combines efficiency and reasonable cost--General use in industrial work. Rugged, efficient--wide range of applications. For a low-cost medium pressure industrial steam line. Standard insulation for residential pipes. For cold hot water lines.'Rccommended especially for air conditioning work. For cold water lines to prevent condensation. To assist in the prevention of freezing in circulating water pipes exposed to cold. In addition to "48" Copr-Fibre Blocks all the above products are also made in sheet and block form for insulating flat or irregular surfaces such as tanks, breechings, furnaces, etc. "48'* Copr-Fibre Blocks Copr-Fibre Blocks are processed from minerals having unusual insulating proper ties and high temperature inorganic bind ing materials. There are two major blocks: No. 18 for indirect temperature service up to 1800 F, and No. 20 for high temperature service to 2100 F and high compressive loads. Both are available in standard sizes and in thicknesses up to 4 in. Most popular of standard sizes are 6 x 12 in., 6 x 24 in., 6x36 in., 12 x 18 in., 12 x 24 in., 12 x 36 in., 18 x 24 in.

Its efficiency makes it satisfactory for most medium pressure steam work in industrial plants. Its construction makes it ideal for vibrating conditions. . It is recommended for temperatures to 600 F. Being an asbestos felt laminated material it is used on vibrating pipes or where hard service is expected. Will withstand water conditions for underground piping. Excellent as an industrial, oil refinery and synthetic rubber plant insulation. Ruberoid Insulating Cements For the finishing of sheet and block insu lation and the - insulating of irregular surfaces, such as valves, unions, flanges, etc., the Ruberoid line of insulating cements is complete. This group of cements not only uses as its base asbestos, but also takes advantage of such excellent natural products as magnesia, mineral wool and Vermiculite.
