Advanced Building Products Mortairvent 202 Rainscreen

MORTAIRVENT® RAINSCREEN – THE CLEAR CHOICE™ Mortairvent® Rainscreen is engineered for superior moisture management in all exterior siding applications. Its advanced design creates a dedicated drainage and ventilation cavity between the weather-resistant barrier (WRB) and the exterior wall, equalizing air pressure and allowing excess moisture to escape. This system helps prevent water damage, promotes airflow, and accelerates drying, ensuring long-term durability and performance. DESCRIPTION Moisture infiltration is inevitable in exterior wall systems—whether through cracked mortar joints, surface gaps, or natural material absorption. Without a proper drainage solution, trapped moisture can lead to mold growth, staining, and structural failure. Mortairvent® is specifically designed for use with stone, stucco, brick, cedar, EIFS, and fiber cement siding, providing a continuous capillary break and ventilation path to keep walls dry and resilient.
