Product Visualizer

An advanced insulation used on furred-out masonry walls, M-Shield™ is designed to resist mold growth by combining a synthetic polymer facing on premium grade aluminum foil. The synthetic polymers contain no cellulose and therefore reduce the risk of exposure to create safer and better air quality. When tested to ASTM standards, M-Shield™ exhibited zero growth of mold or mildew. Remarkably easy to install, Fi-Foil reflective insulation is one of the fastest growing technologies in the world-designed to get you more R-value for less, saving labor and material.

With third-party verified code compliance plus an industry leading 10-year transferrable warranty, in more humid climates, M-Shield™ is a smart choice to insulate all your masonry buildings.
