What about our electrical wiring?

We are often asked what happens if the wiring should ever need to be repaired, replaced or worked on after we spray. We generally install foam in the same order as fiberous batts would be installed – after your plumbing and electrical inspections are complete. Your wires are in the wall and spraying over them buries them. Does this create a problem? No.
First off, it is very rare that electrical wiring is ever changed after inspection.
If it should need to be worked on, it is very easy to run a new wire in between the foam and the drywall because the foam is rigid. Should the original wire need to be accessed after it has been foamed, our Soya based foam is very easy to cut into with a knife, making it easy to access.
The foam itself does not interact or negatively impact electrical wires in any way, and has undergone testing at the Canadian Construction Materials Center to ensure this.
On occasion, we have been asked to instal foam prior to electrical wiring and this can be done because in a 2×6 wall cavity, we generally install 3″ – 3.5″ in depth allowing for the electrical chases to be run in front of the foamed wall. This ensures that the foam does not bury the wires and allows them to move freely in front of and apart from the foam itself. Check with your building code official if this is something that you would like to do to ensure that they are happy with this solution.
