Excellent post - have been arguing this level with my insulation man for years. Within the lighter side, any one else capture the radiant foil/barrier advertisements everywhere? Funny is sweet.
Air sealing and thoroughly-set up insulation need to be the "minimal hanging fruit" that can make radiant heat transfer a insignificant concern. I assume They only Never glimpse as shiny and fascinating to individuals that haven't investigated very best techniques, although.
