Quick Answer
Insulating floors in a traditional ice house involves using materials like foam board, spray foam, or reflective insulation to reduce heat transfer from the earth beneath. A common approach is to add insulation between the foundation and the ice house floor, and also to the perimeter of the foundation. This helps to minimize heat loss.
Preparing the Foundation
To insulate the floor of a traditional ice house, start by preparing the foundation. A 2-3 inch layer of foam board insulation can be placed between the foundation and the ice house floor. This can be achieved by cutting the foam board to fit snugly between the foundation’s piers and the ice house’s floor joists.
Applying Additional Insulation
For added insulation, consider using spray foam or reflective insulation. Spray foam can be applied to the underside of the floor joists, while reflective insulation can be placed between the foundation and the ice house floor. A 1-inch layer of spray foam or reflective insulation can be effective in reducing heat transfer.
Insulating the Perimeter
Insulating the perimeter of the foundation is also crucial to reducing heat loss. This can be achieved by digging a 6-inch deep trench around the foundation and filling it with foam board insulation. The foam board should be cut to fit snugly against the foundation and extend 1-2 inches above the grade. This will help to minimize heat transfer from the earth beneath.
