BASF today announced that closed-cell spray polyurethane foam products have received hurricane-zone approval from the Miami-Dade County Building and Neighborhood Compliance (BNC) Department. Tests and engineering evaluations of COMFORT FOAM® and SPRAYTITE® (178 series) applied at roofing trusses increased the wind-uplift resistance of a traditional code-approved home roof by more than 200 percent. Spray Polyurethane Foam (SPF) from BASF can enhance wind-uplift resistance of new and existing homes to help prevent roof failure during a hurricane.*

Submission of this test data to the Miami-Dade County BNC office resulted in the first Notice of Acceptance (NOA)** for this application with approval for use in High Velocity Hurricane Zones.

“This new hurricane-zone approval adds high-wind mitigation to an already impressive list of product benefits,” said Michael Sievers, Business Manager, Spray Systems, BASF. Sievers added that this specialty application must be installed by a BASF qualified contractor.

The Miami-Dade County NOA indicates that when BASF spray foam is applied as a three-inch fillet along the truss and roof deck, it glues the roof down to provide a simple and cost-effective means of significantly strengthening the roof against failure during high-wind events. BASF also has Florida Building Code (FBC) product approval (FL #13001) for COMFORT FOAM and SPRAYTITE (178 series) SPF products. Adding a total of three inches of closed-cell spray foam under the roof deck will also give the homeowner energy savings and wind resistance. Reduced homeowner insurance premiums may also be an added financial incentive in some areas of the country.

Homeowners in high-wind areas who want to maximize the benefits of COMFORT FOAM, including: premium-insulating values, improved indoor air quality, reduced energy bills and stronger roofs, are recommended to install a three-inch continuous application to the entire roof deck.

What stands tall after the storm may depend on a strong roof 
The National Oceanic and Atmospheric Administration (NOAA) reports that hurricanes account for average insured losses of about 5.2 billion dollars per year in the United States. The majority of these losses were directly caused by severe wind and rain exposure resulting from a failed roof deck, according to a study by Clemson University.

BASF understands the value of providing materials that protect homes during catastrophic weather events including storms, hurricanes and high winds. Particularly vulnerable to these conditions are roofs. According to theFederal Alliance for Safe Homes, if a roof is not properly secured to the rest of a home, the likelihood of structural failure is much greater than if reinforced with hurricane damage mitigation tools.*** This type of application of spray foam glues the roof sheathing to the rafters, giving severe wind and rain no room to enter and weaken a structure.
