Do not excavate the site too far in advance of the scheduled installation date When site has been excavated, insulate the area where the walls are to be placed and cover with a waterproof covering

Insulating Values of Common Building Insulation Materials

Insulation Material

Approximate "R" Values
1" of Straw 2.0
1/2? Plywood 0.6
1" Fiberglass Batt 3.3
1" of extruded Polystyrene 5.0
Insulated Blankets or Tarps Per Manufacturer

Note:  6 " of straw has the same approximate "R" value as 3-1/2" of fiberglass insulation (see chart above). Also, mixing calcium chloride into the stone sub-footer and then covering it will help prevent frost infiltration. Please remember to cover the "extra stone" pile...it may be needed.

Please consult with your Superior Walls sales representative for specific details concerning other measures that can be taken for frost protection at your building site
