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.
