Johns-Manville Marinite Panels are... FIREPROOF and STRONG PLAINTIFF'S EXHIBIT will not burn RSE-17 Marinite panels will not burn because they are composed of incombustible asbestos fibers, diatomaceous silica and a hydrothermally-produced inorganic binder. When requested, Marinite sheets carry the Underwriters' Laboratories, Inc. label with the following Fire Hazard Classification (based on 100 for untreated Red Oak): Flame Spread...................................0 Fuel Contributed............................ Negligible Smoke Developed.............................0 Marinite is also approved by the Board of Standards and Appeals of the City of New York, meeti.ng th_e requirements of C26-88.0 Administrative Building Code as an incombustible material. J-M Marinite was originally developed to isolate and prevent the spread of shipboard fires. It has been used extensively for over a quarter of a century for new construction and the reconversion of American passenger vessels and cargo ships, as well as U.S. Naval vessels. Marinite panels will withstand the concentrated flame from a propane torch without catching on fire, spalling or otherwise disintegrating. light and rugged Large panels of Marinite are lightweight, yet surprisingly rugged and strong, making them ideal for oven and drier construction. load-bearing ability of Marinite 36 panels* uniform load Panel Size, feet 4x8 4x8 4x8 4x8 4x4 4x4 4x4 4x4 2x4 2x4 Thickness, inches 3/4 1 1-1/2 2 3/4 1 1-1/2 2 3/4 1 Ultimate Load, psf 75 125 215 370 130 220 380 640 230 390 Center-Point Deflection, inches Under 20 psf Under 50 psf Ultimate 3/8 7/32 3/32 1/16 5/32 3/32 1/32 1/32 1/32 1/32 13/16 1/2 9/32 5/32 3/8 3/16 3/32 1/16 1/16 1/32 over 1 1 23/32 9/16 _ 5/8 17/32 3/8 5/16 1/4 concentrated center-point load Panel Size, feet 4x8 4x8 4x8 4x4 4x4 4X4 2X4 2x4 Thickness, inches 1 1-1/2 2 1 1-1/2 2 1 1-1/2 Ultimate Load, lb 460 1050 1900 560 1300 2300 690 1600 Center-Point Deflection, inches Under 500 lb _ 5/32 3/32 3/8 5/32 1/16 5/32 Ultimate 21/32 11/32 9/32 15/32 1/4 9/32 _1/4 RS-10064 Tests performed on panels supported on all four edges (each od'j-o having a V Loarimr 'Urfacei and not fastened in nlace. *" * 5 VERSATILE and MOW-CORROD1W many uses Marinite can be readily machined into any size or shape required. Even the most intricate and complex parts have been produced. If you wish, a local J-M Cutter and Fabricator can precision cut parts from your drawings or blueprints. unaffected by water D Marinite panels are non-corroding and will not disintegrate even after prolonged immersion in water. Marinite's bond is so unaffected by water that 1" cubes of the material will actually withstand boiling in water. Try this test and see how sharp the edges remain even after boiling. To test the performance of Marinite under severe moisture conditions, a trial oven was erected at the J-M Research laboratory from six l"-thick layers of Marinite 36. The oven was operated for 300 hours at a temperature of 750F. Throughout the last 204 hours, saturated steam was continously injected so that the oven atmosphere contained approximately 48% water vapor. Result: at the completion of the test, the uncoated Marinite panels were completely unaffected and had a moisture content within their normal range of 5fo. This is because moisture slowly diffuses through Marinite. For example, Marinite 36 has a permeability of 7.6 perm-inches, while Marinite 23 has a permeability of 16.2 perm-inches. (Perms are the number of grains of moisture that a material will pass per hour per sq. ft. of area per inch of mercury vapor pressure differential between the two faces.) On the other hand, a housing constructed of Marinite panels is tight. Many paint driers handle volatile solvents such as methyl ethyl ketone, xylol and toluol. There isn't a trace of solvent odor near these housings.

AVAILABLE IN 3 DENSITIES and 3 FINISHES Marinite 23 Marinite 36 Marinite 65 Type A, B and A C-2 dimensional tolerances To meet varying application requirements, Marinite sheets are manufactured in three densities: 23, 36 and 60 pounds per cubic foot. Has the best thermal insulating characteristics. It is recommended where strength and hardness are of secondary importance, in applications where the material js not-subjected to direct abuse or where it serves as a core for veneering. Provides the best combination of structural strength, surface hardness (comparable to yellow pine) and insulating value. It is recommended for most applications. Recommended where structural strength and surface hardness are of primary importance. Marinite is supplied in three finishes. Type A sheets have a sanded finish on both sides and are recommended for interior use, where painting is not required. Type B sheets are also sanded on both sides, but in addition have an inorganic impregnant, ready for priming, painting or veneering. Type AC-2 sheets are veneered on both sides with 0.086"- thick Steam Cured Flexboard.
