ENGINEERING: The first step in an insulatioo job that will give years of service, such as the Railroad installa tion described below, is to call in an experienced iosulation engineer. Johns-Monvillc maintains a staff of insulation experts. Each man knows how to take the guessworkout of your job...make it "rigbrthe/ri/time." II/c '/IW RIGHT INSULATION: Many types of insulations are necessary to meet varied service conditions. In the johns-Manville Research Laboratory--largest of its kind in the world--new end more efficient insulations have been developed. J-M Insulation Specialists help you choose the right insulation for each temperature re quirement--from minus 400* up to 2800* F. r CORRECT APPLICATION: No io^ sulation is better than the mao who installs it. J-M Insulation Application Units ore In dustry's first choice for completely efficient jobs because (1) Each Unit is trained in all phases of insulation application; (2) Only skilled mechanic* and up-todate application methods are used. You get thorough, dependable and speedy workmanship. 24 YEARS YOUNG1 Johns-Manville Insulations were installed in this power plaat of the Missouri, Kansas, Texas Rail Road Company.at Parsons, Kansas, back in 1923. Because this job was engineered right and applied right, it is still providing dependable insula tion service.
