As buildings are designed to meet higher standards for energy efficiency, durability, and occupant health, material selection plays an increasingly important role in long-term building performance. This one-hour course examines the properties and applications of Silane Modified Polymer (SMP) technology and its role in modern building enclosure design. Participants will review how SMP-based Air Barrier Systems contribute to durable, weather-resistant, and airtight assemblies while accommodating movement across a variety of substrates and environmental conditions. The course also explores installation best practices, applicable performance standards, sustainability considerations, and real-world project applications to support informed specification decisions that improve building resilience, occupant well-being, and lifecycle performance.
