### ⭐⭐⭐ Not worthy

### ⭐⭐ Bad smell
*by A***N on 19 May 2026*

smoking smells comes from it very bad

### ⭐⭐⭐⭐⭐ Easy to install
*by O***A on 7 August 2024*

So much to love about this insulation. First, it can be cut with scissors -- no special equipment required. Installation can be done with a staple gun. There is no itchy fiberglass involved. R value yet to be determined, but at the least it should make a good vapor/wind barrier.
