PowerWool was designed to offer the contractor a greater compression strength to ensure straighter walls while providing exceptional fire-resistance and vapor permeability.
RIGID
More compression resistant than competitors, yet still flexible enough to let siding lay flat.
EXCEPTIONAL R-VALUE
At R-4 per inch, Powerwool helps achieve most US and Canadian energy code and passive house requirements.
VAPOR PERMEABLE
Rigid mineral wool allows trapped moisture to safely escape from your walls for exceptional drying potential.
