att and Steve continue the conversation on air management with a focus on separation. They tackle common challenges and mistakes in building design, particularly regarding ductwork placement. They emphasize the inefficiency of positioning ductwork outside conditioned spaces, which can lead to significant temperature disparities and air leakage issues. Key takeaway: be sure to maintain air barriers in construction.

The conversation delves into effective materials and methods, such as vapor barriers and closed-cell foam, to ensure proper insulation and air sealing. Matt also points out the persistence of outdated construction practices in newer homes, especially in Texas, where ductwork is often found in hot, ventilated attics. They advocate for improved building practices, urging builders to run ductwork within conditioned spaces and maintain air barrier continuity to enhance energy efficiency and indoor air quality.

Armed with this knowledge, builders and homeowners should ask informed questions and strive for better building standards. By adopting common-sense practices and implementing incremental improvements, Matt and Steve believe that significant advancements in home performance can be achieved over time.
