<p>An air-impervious electrical box to facilitate air sealing a house. The box comprises an integral, rigid box body having a continuous flange, integral with the body, circumscribing and outwardly extending from the sides of the body. This flange is rearwardly positioned behind the front edges of the sides of the body a predetermined distance so that the electrical box may be secured to framing by nailing through the flange. Drywall is then secured to the frame on top of and adjacent to the flange. Such box eliminates the necessity for solid backing and minimizes passage of air through the box and spaces between the drywall and the box.</p> |
