  • Right Materials for Igloo Shaping Casa 80

    Reading the installation manual at

    "First, you can create the Igloo using stucco lathe and insulating concrete. The insulating concrete is then covered with a thin finish coat of waterproof stucco."

    Is the insulating concrete layer necessary if using 3" insulation blanket?

    That depemds on how "pefectly" formed that you want the igloo to be. Though, the balnket insuation can be fitted fairly unifornily, it takes a little effort. The vermiculite or perlite concrete can help to get back to a more symetrical dome shape.

      HI Gulf,

      thank you for your response. I ended up using the insulating layer based on your suggestion and the dome ended up being fairly spherical
      thank you for your help
