IMI Webinar Series - Lessons Learned from Masonry Rainscreen Wall Installations
Rainscreen wall systems rely on a balance of design precision and field coordination to perform as intended. Learn how masonry rainscreens manage water, air, vapor, and thermal control through carefully integrated layers that promote the passive removal of moisture from the wall cavity. We’ll explore how different cladding materials, such as terra cotta, natural and engineered stone, tile, and fiber cement, connect to various backup wall types and how these interfaces influence tolerance, sequencing, and overall performance. You’ll also gain insight from real-world installations that demonstrate how thoughtful coordination between designers and installers helps preserve design intent, reduce performance risks, and improve the durability of the building envelope.
Learning Objectives:
- Recognize design and construction tolerance considerations for different types of backup wall systems.
- Understand design and construction strategies that safeguard occupant health by integrating water, air, and thermal control layers.
- Learn how various cladding attachment designs and construction options impact rainscreen wall performance.
- Review rainscreen wall assembly and interface details and assess their impact on sequencing, performance, and material coordination.
