Closed-cell Spray Foam: the Only FEMA Class 5 Rated Flood-Resistant Insulation

Sprayed polyurethane foam and closed-cell plastic foams are the only materials that FEMA classifies as acceptable flood damage-resistant insulation materials for floors, walls and ceilings in its building design criteria for special flood hazard areas (SFHAs).

This requirement applies to new construction, repair of substantially damaged buildings, and substantial improvement of existing buildings in SFHAs. To protect buildings constructed in SFHAs, FEMA’s National Flood Insurance Program (NFIP) requires the use of building materials that are “resistant to flood damage.”
