¹ FM Global Very Severe Hail Standard: Under the FM Global Standard, FM Global tests roof systems for moderate and severe hail impact resistance on how the systems withstand the dropping of a two-inch diameter 1.19 pound steel ball from either 8.1 inches or 141.5 inches. The new Very Severe Hail designation uses an ice launcher to propel a two-inch diameter laboratory-made ice ball at 152-160 feet per second. DensDeck® StormX™ Prime Roof Board is classified for use in approved assemblies that meet these rigid standards for impact resistance. Check for latest information on FM approvals.
