CCMC Approved PowerWool increases the R-value (or RSI) of your project. Resistant to fire and vapour permeable, allowing breathability. Choose PowerWool as your rigid mineral wool choice on your next project.

Why Use PowerWool?

PowerWool was designed to offer the contractor a greater compression strength to ensure straighter walls while providing exceptional fire-resistance and vapour permeability.



Exceptional R-Value


Vapour Permeable

Vapour Permeable

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.
