Steve Baczek tours a home mid-construction with Retrotec's blower door team to check air barrier continuity before insulation and drywall close everything up. Sam walks through the blower door system—calibrated fan, manometer, and the physics of measuring pressure versus airflow—explaining how the setup isolates outdoor reference readings from wind interference. The conversation moves into why airtightness matters beyond energy savings, touching on moisture control, durability, and how tightly interconnected insulation, HVAC, and window performance really are. On-site testing reveals impressively low air leakage, well ahead of passive house targets, and the team uses fog to visualize and pinpoint any remaining gaps in the building envelope.
Huge thanks to today's sponsor, Retrotec.
