Is it ok to use the shower without a ceiling in the bathroom?
Why send all the water vapor into the framing for 3 minutes work with stapler, blue tape and painter's plastic? With the fan on and the ceiling exposed, you would be pulling outside room air in, possibly from the attic or crawl space through every electrical wire and plumbing hole that never got foamed for a number of reasons. Good way to find air leaks coming from or going to those places, though. That is at least a reprimand for an employee. One remodel company I worked for had the laborer demo the fireplace and chimney and wall between kitchen and family room. Never used any plastic, for two weeks, on the 6x3' hole in ceiling to the attic until an Inspector came by and shut the job down. Still using the kitchen with no zip walls! Black bits of insulation floating around everywhere.
Be safe, Gary
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
