Review on Frost King CF55 Natural 12 Inch by Ananta Crowley

I took some of these from a recommendation I saw online somewhere to isolate a standing air conditioner which has a hose leading to the window outlet. The hose gives off so much heat after it's been working hard for a while that it just heats up all the good stuff the air conditioner was doing in the first place. However, this stuff wrapped around the hose and windows has resulted in me and my roommates now being sweaty and often sitting under blankets. I should mention that I installed new windows last year which helped but not that much. This is a MUST HAVE, especially in this price range. If you have even a small window block and cover every gap, you will sleep happily with this material on it.
