We’ve blended high-grade aluminum foil with a tough yet natural layer of kraft paper with an extra polyethylene coating kick. It’s like a dynamic duo for your insulation needs.
Here is where our innovation kicks in. AA2 Shield™ employs expander technology to create a purposeful gap between the foil and paper. This separation sets the stage for reflective air pockets, significantly boosting the insulation’s effectiveness. When installed on furring strips at either 16″ or 24″ intervals, these air pockets perform at their peak, improving thermal properties and energy efficiency.
AA2 Shield™ also features a reflective component, which minimizes the air pocket sizes within the cavity. This contributes to reduced convective heat transfer, which gives your building an environment that’s more comfortable and excels in energy efficiency.
