What Customers Are Saying
Customers overwhelmingly praise this insulation for exceptional thermal performance, ease of installation, and excellent quality. Most highlight how cleanly it cuts, fits standard stud spacing, and installs with minimal effort, with the lightweight 48-inch sections enabling quick completion even on large projects. Reviewers consistently report noticeable improvements in temperature control and reduced heating and cooling costs. The natural color, lack of fiber shedding, and durable construction earn widespread recognition as good value. A few mention minor issues like inconsistent thickness or itchy handling, but these isolated concerns barely diminish overall strong satisfaction.

Quality insulation, easy installation
Would RecommendEasy to install. I’d recommend wearing gloves and a light mask to deal the fibers. Goes in easy and provides a good level of insulation. We used it in our attic space for a boost in energy efficiency. Happy with the results.
