In this AHJ, most of the HVAC contractors will install their rigid ducting, throughout a
SFR [ in the attic space, non-conditioned spaces ] correctly, however, when it comes
to installing the thermal insulation on that rigid ducting, they rarely seal the thermal
insulation joints / seams and points-of-connection to other duct trunk lines &
housings, completely! Sometimes, they overlap the insulation onto other insulation...
Is there a section in the IRC that requires that "all" thermal insulation be fully/
completely sealed with an approved tape or material? No, we don't allow ' general
use gray duct ' tape as an approved sealing tape.
Thanks for your responses!
