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.

Great Product, but many open packages
Would RecommendLove the product and it's easy to install. But for some reason (poor handling?) many of the packages are open at the ends. Others have large gaps in the packaging.
