## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked gre
*by G***N on May 26, 2025*

Worked great to insulate water pipes

### ⭐⭐⭐⭐⭐ Great to keep pipes from freezing
*by A***R on May 8, 2024*

Easy to use.

### ⭐⭐⭐⭐ This is fairly thin and is easily maneuvered against walls
*by R***L on November 6, 2014*

This is fairly thin and is easily maneuvered against walls. The only problem I have is that the supplied vapor wrap it only about 2 inches wide and bunches up easily. I found buying a clear vinyl drop cloth and cutting it into 8 inch strips is much more easily use for vapor wrapping.
