The top of the barrier is a storm collar secured, not secured, to the chimney. Above the ceiling, the air and vapour obstacle is twisted around the drywall to get in touch with the firestop sealer.

Along the edge of common walls. There is typically a gap 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 sealant and stapled to the ceiling encases the electrical box.

This proportion refers to unblocked air vent area to the protected ceiling area.


Do not make use of electrical exhaust followers for attic ventilation as these can attract extra air than can be supplied through the soffit vents. This will actually pull house air into the attic, leading to greater warm loss and dampness buildup. They are additionally vulnerable to failure, sound manufacturing and raised energy use.


The place of vents is as crucial as their number and type. Frequently, a blend of types and places will function best. The following Parts detail the finest technique depending on your attic kind.
