Resist cracking under pressure
from very severe hail

A recent FMI study found that using a cover board on a single-ply membrane roof increased the median life expectancy by four years, reduced operation and maintenance costs by an average of $1.40 per square foot over a 20-year lifespan and increased the percentage of roof assemblies (86% to 52%) that met their full life expectancy, in each case as compared to a single-ply membrane rood roof without a cover board.1 Plus, the enhanced protection of DensDeck® StormX™ Prime Roof Board makes it the only gypsum cover board that is classified for use in single-ply membrane roof assemblies that meet GFM’s Very Severe Hail (VSH) standards.2
