The top of the obstacle is a storm collar clamped, not secured, to the chimney. Over the ceiling, the air and vapour barrier is twisted around the drywall to speak to the firestop sealer.

The 6-Minute Rule for Green Attics

A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling frames the electrical box.

There is often a void in between the event wall surface (such as the common wall surface between devices in duplexes, triplexes and row homes) and the edge of the attic room floor.
