1. What about whole-house ventilation systems (balanced, exhaust only, supply only) and their impact on pressure balance in homes? And do ERVs/HRVs accommodate pressure imbalances created by things like exhaust fans, stack effect, etc.?

2. Per Steve: to butyl or not to butyl...For areas such as door sills, use butyl sealant or maybe acoustical sealant? We know how fond Steve is of Tremco acoustical sealant (a single-component, non-skinning non-hardening synthetic rubber sealant) so this topic gets the big guy on his horse...
