Mouse hole, gas heating pipe and insulation foam

AVbabe219 Member Posts: 1

We just moved and found a few gaps as well as what looks like a small mouse hole by one of our gas radiators. We wanted to try filling the holes with spray foam insulation however with one being very close to a pipe that runs from one radiator to another it made us worried about the foam then flaming up.

Does anyone have any suggestions as to what type of foam insulation we could use or if the radiator would even get hot enough to burn any insulation we place there???

    Even steam temp pipe will not ignite paper.
    Could cause out gassing of any of foam....smells...and looks bad.
    However, the old standard for stopping mouse travel is steel wool packed into the opening. Stainless steel wool would be best. IMO. Then cover the hole with a split ring pipe flange.
