what is the best insulators to replace asbestos insulation?
impossible to get exact numbers without thickness, so i am going to assume you are supposed to neglect it8.32 in21.1328 cm 11 in 27.94 cm so it would be 21.1328cm x 27.94cm surface area would be 2bh the two is there because of front and back2(21.1328)(27.94) 1180.901 cm^2 this is 0.1180901 m^2 make it a good day
There are 2.54 cm in an inchChange the 2 measurements to inches by multiplying then multiply the 2 answers to get the surface area of the foil in cm^2 There are 100cm in M so change measurements to meters before the last multiplying step, then multiply to get the answer in M^2
Synthetic ceramic fibers are manufactured as asbestos replacements and sold in various forms such as non-woven batts, woven forms from blankets to rovings, and molded boards and custom shapesFor high-temperature applications such as kilns and furnaces, a ceramic fiber insulation such as Thermal Ceramic's Kaowool or similar products made from alumino-silicates are the most common replacementFor critical or very high-temperature applications, such as firewalls in aircraft or NASA's Space Shuttle, 3M Nextel or Unifrax Fiberfrax ceramic fiber products may provide better performance.
