Does anyone have any code reference as to why you should not use spray foam insulation inside boxes to seal them? I've been discussing this with a DIYer and he seems to think it's a best practice to fill up most of the box with foam after he has all of his wire run. Thermal insulation material shall not be sprayed or otherwise introduced into the interior of outlet boxes, junction boxes, or enclosures for other electrical equipment.
Yes, it’s generally safe to use spray foam around electrical wires when you do it correctly. When sprayed properly, the foam provides a seal that can prevent air leaks and increase energy efficiency. Use Spray Foam Around Electrical Boxes. When there is no insulation between the back of an electrical box and an outside wall, it may be possible to add insulation behind it. However, be careful not to get the foam . Expanding spray foam without carefully planning can damage electrical wiring. You can prepare any space you want to fill with expanding foam by routing wiring in conduit and making sure not to overfill the cavities where .
The electrical code forbids you from filling the air in the box with spray foam. You've done a pretty good job of keeping the foam out of the box. As long as you don't let the foam encroach on the volume of the box, everything .If there’s plenty of room around your box, you may spray the foam behind it to fill any gap between it and the outside wall surface. We suggest a low-expanding foam because it fills midsized and small gaps uniformly without the need to .
If you’re losing heat that way, you’re best served by sealing the entire attic space and top plates for the walls using fire caulking, acoustical sealant and foam on chases or .

Spray foam is a handy, easy-to-use insulator, but you can’t just use it everywhere. If you’re thinking about spraying it around your outlets and your electrical box, follow basic safety precautions and use it with care.
Gaps around ceiling boxes must be sealed with an intumescent fireblocking caulk or foam. Ordinary spray foam burns too quickly, opening the gap and creating a chimney effect that feeds the fire. Intumescent caulk or foam, on the other hand, swells when heated so it prevents that airflow. Use Spray Foam Around Electrical Boxes. When there is no insulation between the back of an electrical box and an outside wall, it may be possible to add insulation behind it. However, be careful not to get the foam inside the box because it will jam up parts. Plus, many spray foams are flammable. Expanding spray foam without carefully planning can damage electrical wiring. You can prepare any space you want to fill with expanding foam by routing wiring in conduit and making sure not to overfill the cavities where spray foam is being extended. The electrical code forbids you from filling the air in the box with spray foam. You've done a pretty good job of keeping the foam out of the box. As long as you don't let the foam encroach on the volume of the box, everything should be OK.
If there’s plenty of room around your box, you may spray the foam behind it to fill any gap between it and the outside wall surface. We suggest a low-expanding foam because it fills midsized and small gaps uniformly without the need to apply undue force to surrounding materials.
If you’re losing heat that way, you’re best served by sealing the entire attic space and top plates for the walls using fire caulking, acoustical sealant and foam on chases or penetrations. Then insulating your interior walls with something like dense packed cellulose. Does anyone have any code reference as to why you should not use spray foam insulation inside boxes to seal them?
