Just wondering whether there is any advantage of using an insulative blanket made specifically for woodstove liners over using a high-temp blanket such as Kaowool? The only thing I can think of is that a blanket sold for use with woodstoves would probably come with the metal wrap, tape, "staples" or whatever that is used to hold the blanket onto the liner during installation. Any other benefits? BTW. What is the recommended thickness for a blanket? Is there a point of diminishing returns in terms of the thickness?
