Above the ceiling, the air and vapour obstacle is twisted around the drywall to get in touch with the firestop sealer.

Air conditioning repair There is usually a space between the event wall (such as the common wall in between systems in duplexes, triplexes and row houses) and the side of the attic flooring.


A heavy polyethylene sheet which is caulked with acoustical sealer and stapled to the ceiling encases the electric box.
