Frost-Protected Shallow Foundations (U.S. Only)

Maintain a more comfortable, drier environment inside an agricultural building by insulating the ceiling with rigid insulation from Dow.

To prevent frost heaving of uninsulated shallow foundations, building codes in many regions specify that foundations extend below the frost line, requiring additional excavation and concrete. Avoid this extra step - and meet code - by insulating the shallow foundation with extruded polystyrene insulation from Dow. And save time and money while you're at it.

STYROFOAM™ Brand Insulation is an ideal choice for below-grade applications due to its:

  • Excellent moisture resistance
  • Freeze-thaw stability
  • Compressive strength

Choosing the right insulation for your agricultural building depends on what its primary use will be.
