Airtight drywall in mechanical room?
New construction in zone 6b.
I’m planning to go with a belt and suspenders approach to my air barrier. My primary air barrier will be air tight sheathing. My secondary air barrier will be air tight drywall.
Now that I’ve seen the mechanical room and the equipment start to go in, it appears to me that it is not practical to drywall the mechanical room. I’d need holes in the mechanical room drywall for HVAC ducting, ERV ducting, make-up air, domestic plumbing, garden sprinklers, fire suppression sprinklers (required by code), electrical and who knows what else by the time I’m done.
How do people that do air tight drywall manage their mechanical room?
