Dr. Glass is a member of the Building and Fire Sciences Research Work Unit at the Forest Products Laboratory. His research focuses on the building envelope, the collective elements that separate the interior and exterior environments, including the foundation, exterior walls, and roof. Dr. Glass investigates the relationships between moisture, energy efficiency, and durability in residential and non-residential wood buildings. Primary research objectives include: Advancing the fundamental understanding of wood-water interactions; Quantifying moisture transfer in the building envelope; Developing tools for assessing risk of moisture-induced damage in buildings; and Developing moisture control strategies for cross-laminated timber, a relatively new engineered wood product with vast potential for use in mid-rise and high-rise buildings.
