Rainscreen Cladding System

A Rainscreen cladding system is the attachment of a rainscreen panel over, most commonly, a layer of continuous insulation such as mineral wool, an air barrier, and sheathing that is externally fixed onto the core structure of the existing building. This creates a ventilated cavity between the façade itself and the existing building, forming a double-wall construction. This method is designed to keep moisture out while still allowing the building to breathe:

• The inner layer provides thermal insulation and prevents excessive air leakage. The insulation/air barrier/sheathing assembly, which is attached to the existing structure, provides an airtight barrier and thermal insulation to the building.
• The outer layer rainscreen panels act as a barrier against driving rain, ice, snow, and strong winds, preventing moisture from leeching through the exterior walls of the building.
