InterShelter 20ft Polar Dome Package


tax and shipping not included

Home, Emergency

The easy to assemble insulated InterShelter 20ft Polar Dome is a small prefab home that is as strong as a stick built home and as mobile as a tent. It is designed to perform in the most extreme temperature situations from Antarctica to the plains of the Sahara.

  • 314 sq ft, 20 ft diameter
  • Frameless structure
  • Made of easy to assemble durable aerospace composite panels
  • Includes P200O Insulation kit for superior heating and cooling
  • Includes easy to install flooring system that provides a non-slip durable surface
  • Bolt to a concrete foundation to create an indestructible storm shelter
  • Made in the USA
  • Does not come with bathroom or kitchen

Pack the pieces of the InterShelter 20ft Polar Dome on a flat-bed truck and take it where you want to go. Extreme climates are not a problem with the P2000 insulation kit – warm the dome to 72 degrees F when it’s 35 below zero outside with nothing more than a 1,500 watt space heater.

Interior comes “as is” but can be outfitted in a myriad of ways. Interior photos show possible dome furnishings, which are not included with the dome.
