What Customers Are Saying
Customers overwhelmingly praise this insulation for exceptional thermal and acoustic performance, noting warmer homes, reduced energy costs, and significantly dampened noise. Installation is remarkably easy—it cuts smoothly, requires no special tools, causes no skin irritation, and fits snugly into tight spaces, making it ideal for DIY projects and renovations. Most customers declare they will never return to fiberglass, citing superior R-value, better durability, and resistance to fire, mold, water, and insects. A few mention blade dulling during large installations, but this minor drawback is vastly outweighed by overwhelming positive feedback.

Online order was sold by store
Would RecommendMy online order require the purchase of a minimum order of 12 packages of insulation. this was fine because I would require all 12 bundles to insulate my cathedral ceiling.
