Rainscreen Facade
A rainscreen facade is a multi-layer external wall system where the outer cladding layer is separated from the main structural wall by a ventilated air cavity.
The outer layer blocks most rain, while the cavity drains water and allows ventilation, keeping the inner wall dry.

How a Rainscreen Works
- Rain hits the outer cladding
- Most water sheds off
- Any water entering drains down the cavity
- Airflow dries moisture
- Inner wall remains protected
