R values depend on application.
Double reflective insulation r value.
Air space equals r value.
Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own.
An r 1 1 is provided from the product itself for the reflective double bubble material.
If you don t provide air space this product provides almost no insulating value.
Though exact prices will vary by store and region this price ratio is fairly consistent meaning you.

Double reflective insulation r values range from r 3 7 to r 17.
No mess no itchy fibers.
Insulation companies who make metallic bubble wrap or their distributors like to boast about their products attributes and often add the equivalent reflective r values to the conductive values giving an overall equivalent r value.
Are two layers of polyethylene industrialized air bubbles bonded between exterior.

A comparable roll of reflective insulation cost 43 cents per square foot at the same location.
The rubber meets the road on reflectix s website where it says no air space no reflective insulation benefit.
All our reflective double bubble products.
If you install 2 layers of a reflective insulation does the r value double.
The ability to stop heat transfer.
The reflectix double reflective insulation is the most versatile widely distributed energy efficient product that we manufacture.
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.
If the product is simply doubled with no air space between the layers a very minimal benefit is obtained r 1 1 per layer for the reflective double bubble product.
The r values of reflective insulation and mass insulation are based on the same fundamental equation.
Our double bubble products are ideal for metal buildings where the control of condensation is necessary.
