Insulation & Air Sealing
Tight makes right behind tubs and showers—because they can be *ruff* to retrofit
You can dig in to the roof without adding more insulation, but you can't dig far

You can use your hand to detect some air leaks, but smoke puffers make other air leaks easier to "see."

Two packages for high performance homes. Vented and unvented roof insulation retrofits and exterior wall insulation details along with rainscreen wall details for furring strips.
But some buckets are more relative
Why a rain screen wall is important to the energy and durability detailing on a Passive House.
