Knauf EcoFill Wx Glass Mineral Wool Blown-In Insulation
Elevate your home’s energy efficiency with Knauf EcoFill Wx, a premium virgin glass mineral wool insulation designed specifically for weatherization and retrofit applications. This high-performance "blown-in" solution provides a seamless thermal blanket, filling gaps and voids that traditional batts often miss.
The R-19 configuration offers an ideal balance of thermal resistance and material efficiency, covering 106.6 square feet per bag at the specified R-value.
