The use of foam insulation as part of building enclosures has received increased scrutiny in recent years and numerous envelope assemblies have been successfully tested to CAN/ULC S134 or its US counterpart NFPA 285. However, most of these assembly specific tests have been performed on stud wall assemblies. This presentation outlines the results of testing spray foam insulation inboard of a unitized glazing system and demonstrates that these assemblies can also meet the requirements of these standards.
Stéphane P. Hoffman, M. Arch., M. Eng., PE
With a Master’s degree level education that combines structural engineering, building science and architecture, Stéphane brings a well-balanced consulting approach to the building envelope; blending scientific analysis with an understanding of aesthetics considerations. He is particularly adept at providing innovative design concepts and construction alternatives that provide value by improving durability and increasing energy efficiency. As a key technical leader at Morrison Hershfield with twenty six years of experience, Stéphane has worked on projects throughout North America. He led the expansion of Morrison Hershfield’s building science business across the United States and pioneered their Façade Engineering practice focusing on conceptual design of cladding and glazing systems. The last three years he led their Building Science Analytics Group combining Façade Engineering, Energy Modeling and Envelope Component Modeling to assist teams design high performance buildings. As of this summer he now oversees Morrison Hershfield Western US Building Science + Façade practice. Stéphane holds a Master of Engineering from McGill University and a Master of Architecture from the Université de Montréal. He is a licensed professional engineer.
