The Smart Insulation Choice for Masonry Walls

This insulation solution used on furred-out masonry walls, AA2 Vapor Shield™ is remarkably easy to install and effective in improving building performance and comfort. It’s designed to get you R-value for less, saving labor and material. With third-party verified code compliance plus an industry-leading 10-year transferrable warranty, AA2 is a smart choice to insulate all your masonry buildings.

How It Works

We’ve blended high-grade aluminum foil with a tough yet natural layer of kraft paper that has an extra kick of polyethylene coating. It’s like a dynamic duo for your insulation needs.

Here is where our innovation kicks in. AA2 Vapor 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 insulations effectiveness. When installed on furring strips at either 16 or 24-inch intervals, these air pockets perform at their peak, improving thermal properties and energy efficiency.

AA2 Vapor 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.
