Description
There are often gaps between electrical boxes located in exterior ceilings and walls. When warm air leaves the home, it can also carry water vapor that can then lead to mold and rot in addition to increasing the pressure on the heating unit during cold weather months. The LESSCO air vapor box attaches to a ceiling frame or wall to insulate up to three standard electrical boxes. Low expansion foam or a silicon sealant should be used to seal the box at the places where wires pass into the cavity of the wall. Use sheathing tape to adhere the vapor barrier to the box flange. Doing so will prevent air leaks and moisture buildup through electrical boxes. Each LESSCO air vapor box measures 6.5" x 7" x 2.9" deep on the inside and include the hinge feature parented by LESSCO.
