Facing Weather's Fury with SPF

Already well known for its energy efficiency savings in high-performance homes and buildings, BASF spray-applied polyurethane foam (SPF) is gaining recognition for its ability to improve the disaster resiliency of homes and businesses. In fact, closed-cell foams are even recommended by FEMA for homes in flood-prone areas. Its closed-cell construction means it does not absorb water, unlike drywall and fiberglass insulation. More interest in spray foam has been seen following the severe weather events that have occurred in the United States. As seen with the destruction caused by Hurricane Sandy, residents experienced flooding in their homes. The cold snap that followed caused even more damage in the north east. Already wet basements and pipes froze, causing multiple problems.


As a seamless, closed-cell layer in the building envelope, SPF can withstand prolonged contact (72 hours) with water, and is the only insulation that can be left in the home after a flooding event. Closed cell SPF is equally effective for industrial, commercial, institutional or residential structures. Commercial, or "flat," roofing is susceptible to hail damage. From an insurance standpoint damage from hail events is costly. Spray foam offers higher compressive strength and can sustain more of an impact from hail damage better than a traditional roofing system. A spray polyurethane foam roof is fully adhered to the structure, offering double the wind uplift resistance of other roofing systems, giving it a better chance of staying attached in a high wind event. SPF roofing systems offer some of the best warranties in the industry.


  • Mitigate the effects of water, hail or wind-related weather events.
  • Seamless application offers higher R-values than traditional insulation.
  • Increases the strength of walls and ceiling.
