This is the insulation blanket in my Jotul Oslo. It is on top of the 2 piece cast iron burn plates. I replaced if about 6 years ago and it a was about $40 Jotul stealer. For the same price I bought a roll, 2' x 10' roll of Kaowool™ RT - 2,300°F / 1,260°C. It is the same insulation material. The piece I needed is 11.5" X 27" X 1/2". I will be able to get 8 pieces out of the roll.
