Performance+® EcoBatt® Insulation
Engineered to offer the thermal and acoustical properties customers trust, Performance+® EcoBatt® is made with Knauf's ECOSE® technology and validated formaldehyde-free. It is certified to GREENGUARD Gold, the toughest indoor air quality certification in the industry.
Highly resilient, the batts recover quickly to full thickness for a snug fit. They cut easily, resist tears and install quickly with low dust.
