These boxes provide an air tight seal to stop the flow of air through the box and receptacle. The box is made of durable PVC so it is able to withstand extreme environments both cold and hot. You don’t need the vapour barrier behind them and the shape of the box will provide the support for the poly attachment.

Where should a vapour barrier be placed?
Vapor barriers are usually best installed on the side of the wall that experiences the hotter temperature and moister conditions: the inner surface in colder climates and the outer surface in hot, humid climates. In existing spaces, oil-based paints or vapor-barrier latex paints offer an effective moisture barrier.
Can you put fiberglass insulation in an electrical box?
Fiberglass Insulation Around Electrical Boxes

One solution is to use spray insulating foam, such as Great Stuff. If there is enough room around the box, you may be able to spray foam behind the box to fill the gap between the box and the exterior wall surface. Use low-expanding foam, which fills gaps nicely without applying force to the surrounding material.
Do you need to caulk vapour barrier?
Things You’ll Need
Caulk, in conjunction with a vapor barrier, stops air movement cold. Invading air accounts for a third or more of your home’s heating and cooling costs, and cracks also allow entry to insects and pollutants.
Can I use plastic sheeting as a vapor barrier?
Reinforced polyethylene plastic sheeting (poly) comes in a variety of thicknesses and strengths. A 6 mil thick poly is commonly used as a vapor barrier and offers short-term savings to the homeowner.
Do vapor barriers cause mold?
One of the more common problems with crawl spaces that do not have a crawl space vapor barrier system is that they create high moisture levels, which may result in mold growth – as dampness creates the ideal environment for mold growth.
What is the difference between vapor barrier and moisture barrier?
Moisture barriers function to help in preventing water from entering inside of the wall cavity. On the other hand, vapor barriers basically prevent water vapor from the interior of the house to filter through the wall and condense on the warm side of the insulation.
Can fiberglass insulation touch electrical wires?
It is perfectly safe for household insulation to touch wires provided the wires or cables are electrically insulated. There also are techniques to make insulation fit better around wires. However, under no circumstances should thermal insulation make contact with live uninsulated wires and cables.
Can electrical junction boxes be covered with insulation?
“Junction boxes can be covered by insulation in such a manner that it can be removed without damaging it to access the box. Foamed-in-place insulation isn’t removable and therefore not permissible.”
Can Romex touch insulation?

Can you bury Romex without conduit?
Buried or exposed wiring will need to be listed for its application. Underground feeder wiring can be directly buried without a conduit with a minimum of 24 inches of cover. Any wiring placed inside intermediate metal or rigid metal conduits will require at least six inches of ground cover.
Does wiring need to be behind insulation?
Wiring should be installed before any insulation. When building a home, everything needs to be done in the correct order. For instance, after the framing is complete and the exterior walls have been put up, you need to consider the inside of the wall cavities before you drywall the interior.
