This document discusses hail impact testing conducted at the IBHS Research Center. It notes that over 75% of US cities experience hailstorms annually, which can cause billions in damages. The goals of the research center are to reduce hailstorm impacts through testing building materials and developing methods to accurately simulate natural hailstones, including varying sizes and densities. Initial testing will focus on artificial hailstones from 1-3 inches in diameter with different compositions and freezing conditions to replicate natural hailstone properties. Conglomerate hailstones will also be tested to match real-world hailstone formations.
