The Build Show Podcast

Matt Risinger talks with Jason Todd of TimberHP about the growing role of wood fiber insulation in high-performance construction. Todd explains how wood-based insulation products fit into modern wall assemblies, offering vapor-open performance, thermal control, and compatibility with airtight building strategies. The discussion covers manufacturing, supply chain challenges, and how these materials compare to foam and mineral wool in durability and environmental impact. They also touch on prefabrication, evolving building codes, and the shift toward low-carbon materials in residential construction.

Matt Risinger sits down with Bill Graber and Steve Rogers of The Energy Conservatory to explore how diagnostic testing informs high-performance construction. The conversation centers on blower door testing, pressure mapping, and airflow measurement as tools to verify airtightness and identify leakage pathways. They discuss how builders and energy raters use data to refine building enclosures, improve indoor air quality, and coordinate HVAC system performance. The group also touches on evolving codes, training, and the growing expectation for measurable results in residential construction.

Matt Risinger hosts a conversation with Bill Spohn and Eric Kaiser of Tru Tech Tools, focusing on how testing and measurement shape modern building performance. The discussion centers on blower door testing, airflow diagnostics, and the growing role of data in verifying airtightness and system performance. They explore how builders and HVAC professionals use tools to identify leakage, improve indoor air quality, and fine-tune mechanical systems. The conversation also touches on training, evolving standards, and the shift toward performance-based construction, with practical insights into integrating diagnostics into everyday building workflows.

Matt Risinger sits down with Jacob Racusin of New Frameworks to unpack how straw-based construction fits into modern high-performance building. Racusin reframes “straw bale” as a panelized wall system using straw and wood fiber as insulation within airtight assemblies, emphasizing durability, moisture management, and prefabrication. The conversation moves from the history of straw construction to its evolution into factory-built panels that meet passive house–level performance. They discuss cost, scalability, and shifting from custom design-build to standardized housing solutions, positioning bio-based materials as part of a broader strategy for energy efficiency, resilience, and streamlined construction.

Matt Risinger centers the conversation on blower door testing with Building Scientist Sam Myers from RetroTec, exploring how it functions as a practical tool for measuring and improving air tightness in residential construction. Myers outlines design choices that influence results, including keeping mechanical systems inside the conditioned envelope and minimizing major air leakage pathways. The discussion covers blower door equipment, typical costs, and training options, while emphasizing the value of builders owning and operating their own systems. Risinger frames testing as a hands-on method to diagnose air leakage, compare performance across projects, and refine construction practices in real time.
