There are many choices in INSULATION, they all have advantages and disadvantages. This week we look at Blown-in STONEWOOL INSULATION as our choice out at our Field Of Dreams Project. Manufactured by American Rockwool, this stonewool insulation gets blown into all wall cavities and in the attic. It’s fire resistant, insect resistant, mold resistant, and has an R-value of 4.1 /inch. For these reasons and more discussed in the video, it was a perfect fit…..for a “PERFECT WALL”………Enjoy
