Wall Ventilating and Draining Solution

Keene Building Products and Amico have joined forces to combine their moisture solutions to offer an ICC code compliant, self-draining vented wall system for use behind stucco, veneer stone, fiber cement and other exterior claddings. This innovative combination creates a dedicated drainage cavity behind exterior walls by utilizing Keene’s Driwall™ Rainscreen products.


Exterior walls are then ventilated and drained with Amico’s patented, ICC-certified Hydrodry® System. This allows walls to sufficiently dry out and releases any moisture caused by condensation or water intrusion extending a wall’s useful life by promoting proper drainage and ventilation.


The latest ICC and Florida commercial building code 2510.6 requires that all new commercial buildings built with wood-based sheathing in climate zones 1A, 2A or 3A are required to have a ventilated airspace between the stucco and water-resistive barrier. The Keene/Amico Hydrodry® Solution provides this airspace and allows it to ventilate properly to prevent mold, mildew or bacteria.


Keene Building Products Driwall™ Rainscreen is a drainage mat for exterior wall systems. The structured strand product eliminates incidental moisture problems in most exterior veneer applications, including stucco, manufactured stone and plank siding.


The full-wall Driwall™ Rainscreen product rolls over the water-resistive barrier to separate it from the exterior veneer. The airspace that Driwall™ Rainscreen creates increases airflow through the wall cavity, allowing the wall to breathe and stay dry.,
