Cooling My Garage
Would RecommendInstalled 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.

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.
