BASF specialty application for strengthening residential roofs during high-wind events approved by Miami-Dade County

October 5, 2011

Cost-effective, BASF spray foam attic-truss installation can improve roof strength by 200 percent.

BASF's 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.
