Houston, Texas -- BASF said 5 Oct that closed-cell spray polyurethane foam products have received hurricane-zone approval in Florida 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, said BASF.
Spray polyurethane foam (SPF) from BASF can enhance wind-uplift resistance of new and existing homes to help prevent roof failure during a hurricane.
BASF said that 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.
In a statement, Michael Sievers, business manager, Spray Systems, BASF, said: "This new hurricane-zone approval adds high-wind mitigation to an already impressive list of product benefits." Sievers noted that this speciality 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 the same 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, BASF said.
Reduced insurance premiums may be an added incentive in some areas of the country.
