Microfoil™.

Reflective Foil Insulation

MicroFoil reflective insulation is a thin, lightweight, 97% Radiant and 99.995% Vapor Barrier.

MicroFoil has our patented 1" self-taping foil flange running down one edge (48" and 72" widths only) with an additional 1" flange running down the opposite edge the entire length (16" and 24" rolls have staple flanges on both sidesfor inside joist/wall cavities).

#1 Reflective foil insulation to use under metal roofs, in attics, walls, and with radiant infloor heating systems. MicroFoil ™ is a clean, non-toxic, easy to install, self-taping radiant barrier that provides increased comfort, energy efficiency, and savings.

MicroFoil ™ effectively reflects a heat source as opposed to absorbing and dissipating it as fiber glass insulations do. This reflectivity works both ways: radiating summer heat outward and retaining winter heat inside.

Radiant Barriers do not have an R value since the R-value for reflectivity cannot be measured. However, radiant barriers can be tested as part of an assembly where the R-value can be observed and measured. In this case, the R-value can be achieved when the radiant insulation is installed as tested. R-values cannot be estimated based upon different installation methods.

R value is a measure of thermal performance, the higher the R value the greater the insulating value.

Independent testing by US Testing Laboratories

When installed correctly, MicroFoil™ provides an excellent thermal and vapor barrier, greatly reducing condensation buildup.

• MicroFoil does not contain hazardous chemicals or harmful materials that cause itching or respiratory problems.
• Condensation control
• Scrim reinforced for strength and durability
• Lighter and easier to handle than other products

If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly.

Radiant Barriers do not have an R value since the R-value for reflectivity cannot be measured.  However, radiant barriers can be tested as part of an assembly where the R-value can be observed and measured.  In this case, the R-value can be achieved when the radiant insulation is installed as tested.  R-values cannot be estimated based upon different installation methods.

Read This Before You Buy: The chart shows the R-value of this insulation. R means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend on climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size.
