Foam insulation for walls is an excellent option in properties and commercial buildings built in areas that flood regularly. Even when in direct contact with the earth, expanded polystyrene, as a material, does not degrade over time. It absorbs very little of the water or moisture when in a flooding situation and also dries out completely once the water source recedes. To get the benefits of the insulating properties of eps foam, the sheets can be used either on the outside of the wall framing or between the studs.
