Being in Canada the inspector will want to see a 6mil poly barrier applied over the insulated wall/ceiling. After it goes on you cut the poly barrier around the outside of the electrical box. Pull the electrical box vapour barrier out so the 4 sides are over top of the poly barrier. Use 3m tape or even tuck tape to seal the 4 sides to the poly. The manufacturer of Airfoil airtight electrical boxes, Doug McEvers, suggests that polyethylene should be sealed to the box flanges with Tremco acoustical sealant. (See photo, below.) I strongly suggest that you don't install any recessed can lights in an insulated ceiling, since these lights (even "airtight" versions) are responsible for air .
Two architects have come up with an inexpensive way of air-sealing and insulating electrical boxes in exterior walls. After puzzling over the best way of meeting a code requirement for sealed boxes, Bill Hicks and Lucas Schad developed a cardboard form called the Box Shell that wraps around an electrical box. The form is slightly larger than the box, creating a small . These electrical devices sit inside an electrical junction box, so that connects air in the house to air in the junction box. To get electricity to the switch or receptacle, wires have to come into the box. The photo below shows the back of a typical junction box, with all its holes. Take a look at all those holes.The 4 square box is commonly available in 1-1/2” and 2-1/8” depths (a “deep” box). There are many ways to mount the box depending on your wall. You could use the shallower box with a 1/2” piece of foam behind it, for example, and the box screwed into the wall through the foam. You could use a box with “wings” to mount to a stud. Plans called for a piece of conduit to be routed through the exterior 2×8 wall and into the electrical box. The conduit would be sealed to the OSB air barrier on the interior with tape and acoustical sealant. Once the wire is routed through the conduit, the conduit will be filled with spray foam. The detail looked fine on paper.
electrical box air sealer
It’s a meter main combo box with underground service. Has one service wire to an interior 200a panel that goes through the back. I’m thinking I can just install it directly to the zip sheathing and build a channel under it for the conduit. I’ve done enough old-work electrical that I’ve been frequently annoyed by having basically no slack to work with at the junction box. When installing my own wiring, I therefore try to leave a decent amount of slack in a service loop that can be pulled out of the wall for future work (e.g. needing to re-strip the ends, getting a light .
