HydraShell® AIRX-30™ is a breathable underlayment engineered to allow trapped moisture within the roof system to escape, helping roof decks dry after exposure to rain or snow during construction. Its moisture-release capability helps prevent mold, mildew, and structural damage, while its textured, slip-resistant walking surface delivers superior safety and productivity during installation. Approved for use under multiple roofing materials and compliant with ASTM D226, ASTM D4869, and AC 188 standards, AIRX-30™ is a smart upgrade for premium roofing systems that demand long-term performance and protection.
HydraShell AIRX-30 is a premium multi-layered structure with a slip-resistant textured top surface
combined with our advanced breathable Moisture Release Technology (MRT). MRT actively assists in drawing trapped moisture from within the roof system and releasing it to the outside air.
