Double reflective insulation r values range from r 3 7 to r 17.
If you don t provide air space this product provides almost no insulating value.
The ability to stop heat transfer.
With multiple layers of product and airspaces between each layer enhanced performance will be gained.
R values depend on application.
A comparable roll of reflective insulation cost 43 cents per square foot at the same location.
No mess no itchy fibers.
Air space equals r value.
Double bubble insulation is the most effective bubble insulation with highest r value.
Reflective insulation is a system that reduces the transfer of heat across air space by the use of two surfaces having high thermal reflectance and low emittance typically metalized film.
