Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Best Insulation for my pipes I didn't know I could use this insulation over a heat cable. I bought this and a heat cable to use on my water pipes and have noticed a big difference this winter. January 11, 2013
Rated 5.0 out of 5.0 by Fits well, works great We had a couple of 20 degree nights, got concerned about our outside pipes. This insulation fits well, is thick, and will help ease my mind during the cold or hot weather. January 1, 2014
