Can electrical wires be covered with insulation?
Yes, you absolutely can. You can lay insulation around the junction boxes as well. Making sure that the insulation is of a fiberglass material will not only ensure a fireproof setup but also reduce airflow from the home through the attic.
Do wires go under or over 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.

What material would be safest to use as an insulator to cover electrical wires?
Some materials such as glass, paper and PTFE, which have high resistivity, are very good electrical insulators.
Can you run Romex through insulation?
Yes, you can. RetroFoam insulation is both soft and pliable. Its composition makes it very easy to fish electrical wiring through the injection foam insulation.
Can you put expanding foam around wires?
You have to consider if using foam is safe if you have anything routed inside the cavity, such as electrical wiring. So, if you were wondering whether expanding foam damages wiring the answer is yes. Expanding spray foam without carefully planning can damage electrical wiring.
Can you use spray foam insulation around electrical wires?

How do I insulate an outlet box?
Another simple step for better outlet insulation is to apply foam or caulk into the gap around the flush-mounted box, behind electrical cover plates. After foam hardens, you can slice off the excess with a serrated knife. To seal wall boxes, first seal the cable intrusions and then the gap around the box.
Can you caulk around wires?
For wiring holes (e.g., security system wiring, television and internet cables, exterior outlets, and switches) use caulk, gaskets, spray foam, or other approved sealants to seal any gaps or holes.
Where should you not use expanding foam?
When NOT to Use Spray Foam Insulation
- For areas that are too close to electrical boxes:
- For areas too close to ceiling light boxes:
- Open-cell spray foam on your roof:
- For closed-cavity spaces:
- If you have a history of skin, respiratory, or asthma problems:
Does WD 40 Remove expanding foam?
WD-40 can be used to remove expanding foam. You can use the straw that it comes with to spray the insulation, and it will dissolve. Keep in mind that open-cell spray foam expands significantly more than closed-cell spray foam.
Do mice eat expanding foam?
Generally, mice have no attraction to spray foam insulation, as it doesn’t represent a food source. And if a mouse should somehow enter the attic space (even after installation), the spray foam envelope has no material content that mice would want to eat.
