There is often a gap in between the event wall surface (such as the common wall in between systems in duplexes, triplexes and row houses) and the side of the attic room flooring.


A hefty polyethylene sheet which is caulked with acoustical sealant and stapled to the ceiling frames the electrical box. An electrical cable leads away from the electric box and down with an opening into an indoor wall. Holes around electrical cords are loaded with caulking or foam sealant, and caulking seals voids along the top of the interior wall surfaces.
