There is frequently a space between the celebration wall surface (such as the common wall between systems in duplexes, triplexes and row residences) and the edge of the attic flooring.

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

Homes with peaked roofs and accessible attics are the easiest to vent by utilizing the proportion of 1 to 300. This ratio describes unblocked vent location to the insulated ceiling area.

Likewise, do not use electrical exhaust followers for attic room air flow as these can draw more air than can be supplied via the soffit vents. This will really pull home air into the attic, resulting in higher heat loss and wetness build-up. They are also prone to failing, noise manufacturing and enhanced energy use.
