Great to stuff small areas
Bought this to stuff in air void areas under sink in metal building. Used total of 3 packages to stuff between wall and metal outside. Had air gap that caused incoming water line to freeze. For 20 years, every winter, that water line froze.......after my quick fix....no more freezing. Hooray for me - the building was passed on to me......I solved the problem. Plumber suggested this to save me paying professional time.
