M-Shield™ Reflective Insulation for Masonry Walls - 24"

M-Shield™ is an advanced reflective shield insulation designed to resist mold growth by combining a synthetic polymer facing on premium-grade aluminum foil. The synthetic polymers used on reflective walls 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. Easy to install, designed to get you more R-value for less, saving labor and material.
