Review: Good addition, minimal effort. - I am using this for a bathroom remodel. The original fiberglass wall insulation was insufficient on this cold, northwest corner of the house, but this will be a huge improvement. It is easy to work with and cut, and the minimal thickness adds a decent R-value AND radiant factor.

### ⭐⭐⭐⭐⭐ Works great!

Easy to work with and insulates very well.

### ⭐⭐⭐⭐⭐ Very nice insulation and easy to work with
*by S***. on August 22, 2025*

I needed to replace all of the duct insulation on a home I purchased due to rat damage that was found in the presale inspection. This is a great way to cover my ducts. I have installed it with two wraps of 1" strips to provide the needed air-space. Eacy to work with and much nicer than the itchy fiberglass alternative.
