Course Title: Bio-Based Insulation
Delivery Method: Live Online
Course Description: This two-hour course introduces bio-based insulation materials and examines how natural fibers, agricultural by-products, and low-carbon binders can be integrated into building materials and assemblies. Discussion emphasizes hygrothermal behavior, code-conforming design, and how rural, circular economy material streams contribute to healthier, lower-impact building projects.
Learning Objectives:
Learning Objective 1: Learners will be able to identify common bio-based insulation materials, such as cellulose, hemp, straw, wood-chip composites, and other agricultural fibers, and explain their sources, composition, and binders.
Learning Objective 2: Learners will be able to analyze key building considerations for bio-based insulation, including moisture content, thermal mass, hygrothermal performance, and compatibility with site built or panelized assemblies.
Learning Objective 3: Learners will be able to evaluate code compliance requirements, design goals, and performance metrics necessary to specify bio-based insulation safely and effectively.
Learning Objective 4: Learners will be able to assess the environmental and economic benefits of natural fiber insulation, including carbon sequestration potential, circular economy impacts, and rural material-supply opportunities.
