PowerWool was designed to offer the contractor a greater compression strength to ensure straighter walls while providing exceptional fire-resistance and vapour permeability.
RIGID - Designed to be more compression resistant than the leading competitive product for most similarly recommended applications. Contractors asked us for a more compression resistant product but one which also still has enough ‘give’ to allow siding to lay flat, for example, when rainscreen furring strips are installed overtop of PowerWool in an exterior siding application.
EXCEPTIONAL R-VALUE - At R-4 per inch, Powerwool helps achieve the new British Columbia Energy “Step Code” Requirements and most US and Canadian energy code and passive house requirements.
VAPOUR PERMEABLE - More permeable than most “breathable” housewraps, rigid mineral wool allows trapped moisture vapour to safely escape from your walls for exceptional drying potential.
Available in various densities for various applications with more coming soon. Today available as Powerwool Rigidboard for wood-framed walls and sound abatement applications. Coming soon will be:
