The core IBHS research facility is a specially designed, open-jet wind tunnel capable of subjecting full-scale, one-and-two-story structures to a variety of wind hazards. Small lab capabilities include a wind tunnel that can reproduce ASTM D 3161 and ASTM D 7158 wind tests and extend test wind speeds up to about 180 mpd for ASTM D 3161 and about 110 mph for ASTM D 7158. Additional capabilities include replicating UL 2218 and FM 4473 impact tests. Hail capabilities have expanded to include impacting specimens with lab-created realistic hailstones. 

The IBHS asphalt shingle research programs seek to develop credible relationships between test standards, product ratings and real-world performance in wind and hail events. Read more
