Hi guys,Recently I have been trying to block up any gaps or possible entry points for rodents, and along these cavities in the corrugated metal sheets for the extension part of the house, I put steel wool and then some expanding foam on it.Picture for reference: http://ift.tt/2qkSZQU read around that steel wool catches fire easily, so I was worried, say if a lightning strike strikes that part of the roof, would it be an issue? Or is steel wool perfectly safe in this type of situation or placement?Cheers! via /r/DIY http://ift.tt/2lLUnaw
