Fi-Foil AA2 Vapor Shield™ is a reflective insulation intended for use onfurred-out masonry walls. The inside layer is a minimum .00035"aluminum foil. The outer layer is 35 lb. natural kraft paper coated withpolyethylene, laminated to flange boards or expanders that separate thepaper from the foil creating a reflective air space. When installed onfurring strips spaced 16" or 24" on center, a second reflective air spaceis formed. This air space is dependent upon the thickness of the furringstrip selected. The Hi-Perm version includes small perforations forapplications not requiring a vapor retarder.

The R-values of AA-2 VaporShield increase with the thickness of furring strips. Withthe use of Vapor Shield, the thickness of furring stripsare slightly increased because it is applied to thesurface of the strips and overlaps. Therefore allmeasurements are considered nominal.

Compliance and Approvals

READ THIS BEFORE YOU BUY

The label shows the R-value of thisinsulation. R means resistance to heatflow. The higher the R-value, the greaterthe insulating power. Compare insula-tion R-values before you buy. There areother factors to consider. The amount ofinsulation you need depends mainly onthe climate you live in. Also, your fuelsavings from insulation will dependupon the climate, the type and size ofyour house, the amount of insulationalready in your house, and your fuel usepatterns and family size. If you buy toomuch insulation, it will cost you morethan what you will save on fuel. To getthe marked R-value, it is essential thatthis insulation be installed properly.

Standard and Hi-Perm Versions

How Reflective Insulation WorksHeat is transferred by one of three methods, which include conduction,convection and radiation. In general, any material added to a cavity increasesconduction across that air space. Most insulating products on the market resistheat transfer by forming small air or gas pockets between layers of buildingmaterials such as fiberglass, recycled paper, and foam. The small spaces restrictair movement, thereby reducing heat flow by convection. However, thesestandard building materials are not as effective against radiant heat transfer.Reflective insulation functions by forming these dead air spaces with layers ofpaper, plastic, and aluminum. The high reflectivity and low emissivity of thealuminum material has the added benefit of blocking radiant energy, so heattransfer through radiation is also significantly reduced. Reflective insulationprovides resistance to heat gain in summer conditions and heat loss in winterconditions. This lowers both cooling and heating costs, reducing energyexpenditures throughout the year.
