Do Not Overinsulate Kiln

All Cautions


  1. You may add insulation to the bottom, and to some extent the top.
  2. If you put too much insulation on a lid it may weaken because it relies on the cooling of the lid to maintain its structural strength. This could lead to cracking or potentially a collapse of the lid.
  3. See the various troubleshooting guides for information about this.
  4. However, never wrap insulation around the perimeter of a typical sectional kiln.
  5. You could trap heat in the wiring boxes and cause an electrical fire.
  6. Also the stainless steel wrap that hold the kiln together will expand and loosen the structure of the kiln.
