Sealing electrical wiring ceiling air barrier penetrations – GreenBuildingAdvisor

Turns out our electricians failed to comprehend what we meant when we said no drilling into the ceiling air barrier OSB or top plates… Our carpenters rabbited channels into the ceiling strapping to put wiring through… But instead they chose to go through the attic and come down, cutting like 10 holes in our precious ceiling air barrier. Apparently there was “no other way” to get the wiring into these interior partition walls (the interior walls are being built after the slab is done).

This is very annoying, but perhaps it is not a big deal. In my mind it’s a HUGE DEAL because we specifically said to avoid doing this and explained where they could run wiring.

Now that we’ve got all these holes, what is the best way to seal them?
