Design practices increasingly rely on exterior insulation to meet energy codes and continuous insulation requirements. This shift brings new challenges, particularly related to NFPA 285-compliant wall assemblies, moisture management, thermal continuity, and long-term durability.

This presentation explores the performance of exterior insulation under the demanding conditions of modern rainscreen systems and masonry veneers, with a focus on NFPA 285 compliance, thermal bridging, moisture transport, durability and sustainability. Attendees will gain insights to help design, specify, and install exterior insulation to optimize performance while avoiding potential issues. 

Learning Objectives:

1. Explain building code requirements and testing methods for fire propagation and smoke development, with a focus on understanding the NFPA 285 assembly test in relation to modern wall assemblies.
2. Evaluate insulation properties related to water, air, thermal, and durability in rainscreen systems and masonry veneers to inform insulation selection.
3. Identify challenges such as thermal bridging, multiple drain planes, drainage efficiency, water absorption, and vapor transmission to better support effective wall system design.
4. Asses the manufacturing and sustainability characteristics of continuous insulation options to support specification decisions that reduce operational carbon footprints.
