What Customers Are Saying

Customers overwhelmingly praise this insulation for exceptional thermal performance and ease of installation. Most report immediate improvements in home temperature control and lower energy bills, with many citing the R30 rating as highly effective. Reviewers consistently describe it as easy to cut, roll out, and handle between joists and attic spaces. A major advantage customers highlight is significantly reduced itchiness compared to traditional fiberglass, making installation more comfortable. A few note minor thickness inconsistencies or initial odor, but these isolated concerns do not diminish overall strong satisfaction. Most customers consider this a reliable, user-friendly choice for effective home insulation.

Cooling My Garage

Would Recommend

Installed this R-30 insulation in my garage attic to help with the Florida heat. It made a noticeable difference and helps my AC keep the garage cooler. Easy to install and fits well between the joists. A little itchy and messy, but overall a great product. I would definitely recommend it.

As expected

Would Recommend

It's insulation. It's exactly as you'd expect. This is unfaced. We bought it for insulating around ductwork.

The roll was larger than we needed but we wanted the higher R value. Did our whole crawl space. Hopefully, make the floors feel warmer.
