Radiant Barrier Foil Tips - Learn about Air Space

Video Description: http://atticfoil.com/radiant-barrier-instruction.htm Why Is An Air Space Required For Radiant Barrier? Ed Fritz, the owner of AtticFoil.com illustrates why you MUST have an air gap on at least one side of the radiant barrier foil insulation for it to be effective. In fact, without an air gap, heat flow is actually accelerated through conduction or conductive heat flow. Ed also explains and demonstrates the difference between reflectivity and emissivity.
