Is it safe to spray icynene spray foam insulation over electrical wiring and plumbing runs?

While Icynene spray foam insulation has been extensively tested and found to be safe, we do recommend that you consider using a conduit or service cavity for electric wiring. This will help if in the future you need to correct a faulty wire or connection.

Of course, covering over plumbing runs with the world’s leading market home insulation product is worth doing for protection against your pipes freezing up!

 

You can see here documentation from relevant authorities around the safety of covering wires and pipes with icynene.
