Live from the ROCKWOOL studio, Matt and Steve explore how to design and construct homes optimized for extreme health, focusing on mold resistance, superior indoor air quality (IAQ), and moisture control. They discuss essential strategies such as building tight, well-ventilated homes to prevent mold growth, using high-performance dehumidifiers, and implementing advanced HVAC systems with MERV 13+ or HEPA filtration. Matt and Steve highlight the importance of managing bulk water through proper site grading, overhangs, and pitched roofs while also considering leak detection systems and waterproofed mechanical rooms.

For improved air quality, Matt and Steve emphasize eliminating duct board, minimizing flex duct, and opting for metal ductwork, which is easier to clean and prevents microbial growth. They also discuss alternatives to standard drywall, such as fiberglass-faced drywall, American clay plaster, or traditional lath and plaster to reduce mold risk. Additionally, ductless HVAC systems, like mini-splits, can further enhance IAQ by eliminating dust-collecting ductwork.

The episode also touches on cost considerations, with case studies showing how clients with severe allergies or mold sensitivities have significantly benefited from controlled indoor environments. Whether you're a builder, architect, or homeowner looking to create a healthier home, this episode provides expert insights into mold-resistant construction, high-IAQ design, and smart moisture management. Listen now for a deep dive into building science solutions for extreme health.
