Specifically Engineered for Optimal Performance in Masonry Wall Applications.
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, 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 transferable warranty, in more humid climates, M-Shield™ is a smart choice to insulate all your masonry buildings.
M-Shield™ has two layers. The inside layer is aluminum foil. The outer layer is a synthetic polymer material and the product is designed with small perforations to allow vapor transmission for applications not requiring a vapor retarder.
Our technology uses expanders that separate the paper from the foil to create reflective air spaces. When installed on furring strips, 16” or 24” on-center, air is trapped inside the cavity and the reflective components improve performance of the air space.
Since the reflective layers also reduce sizes of the air spaces in the cavity, reflective insulation also reduces heat transfer by convection. The result is a more comfortable building and better energy efficiency.

Yes. The ASHRAE Handbook values are a subset of data from the National Bureau of Standards (NBS).
As building envelopes are getting tighter, building scientists, energy centers and research organizations are suggesting that insulation products and facings used in hot humid climates have higher perm ratings for increased water vapor transmission. Fi-Foil's Hi-Perm versions are designed to meet or exceed these recommendations.
Reflective insulation is one or more low emittance surfaces installed in an enclosed air space. The more layers within the air space, the better the performance. Reflective insulation in a wall system can be compared to a double or triple pane window with low-e surfaces. Triple pane windows with low e surfaces perform better than a triple pane window without low e surfaces because of the reduction of radiation (low emittance) across the air spaces. Air inherently has an R-per-inch value of 5.6, and is an excellent insulator when radiation and convection are controlled. The ASHRAE Handbook has tables with values for various enclosed air spaces (0.5”, 0.75”, 1.5”, 3.5”, etc.) with high emittance surfaces (0.82 for common building materials) and values for air spaces with low emittance surfaces facing the enclosed air space (0.05 for low emittance materials like aluminum). Simply put, adding a low e material makes the enclosed air space perform better. A multilayer reflective insulation system in a wall cavity improves this system by further reducing radiant heat transfer and adding additional “panes”, a two layer reflective insulation could be compared to a double paned window; a three layer to a triple pane window, and so on.. The installation of reflective insulation in an enclosed space reduces thermal radiation to near zero. When the reflective insulation is installed to subdivide an air-filled region then heat transfer by convection is also reduced. Fi-Foil has single layer, two layer, three layer and even honey-comb layer reflective insulation products for various building applications, each with different performance levels and attributes for the particular application. These products also work very well with other types of mass insulation as hybrid systems by using the best attributes of each of the technologies (e.g. spray foam is great for air sealing and can have a high R--value per inch of thickness -- fiberglass and cellulose is an inexpensive material to reduce convection in the cavity). In some wall systems, especially wall cavities larger than 1.5”, a combination of reflective insulation with one or more of these mass insulation products, addresses all the modes of heat transfer -- often more cost effectively than one of the technologies used alone.
Reflective insulation has little effect on heat transfer by conduction through the air between hot and cold surfaces. Air with an R-per-inch of 5.6 is an excellent insulator when radiation and convection are controlled. The installation of reflective insulation in an enclosed space reduces thermal radiation to near zero. When the reflective insulation is installed to subdivide an air-filled region then convection is also reduced.
