A comparable roll of reflective insulation cost 43 cents per square foot at the same location.
Double reflective insulation r value.
Some products say r4 r6 or r8.
The ability to stop heat transfer.

Though exact prices will vary by store and region this price ratio is fairly consistent meaning you.
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.
R values depend on application.
Double reflective insulation bp48025 48 x 25 100 sq.
The r values of reflective insulation and mass insulation are based on the same fundamental equation.
Double reflective insulation r values range from r 3 7 to r 17.
An r 1 1 is provided from the product itself for the reflective double bubble material.
Thd sku 469837.
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.
If you install 2 layers of a reflective insulation does the r value double.
No mess no itchy fibers.
Double bubble insulation is the most effective bubble insulation with highest r value.
Our double bubble products are ideal for metal buildings where the control of condensation is necessary.

If you don t provide air space this product provides almost no insulating value.
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.
Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own.
All our reflective double bubble products.
With multiple layers of product and airspaces between each layer enhanced performance will be gained.
Air space equals r value.
Are two layers of polyethylene industrialized air bubbles bonded between exterior.
The rubber meets the road on reflectix s website where it says no air space no reflective insulation benefit.
