If you don t provide air space this product provides almost no insulating value.
Double reflective insulation r value.
The rubber meets the road on reflectix s website where it says no air space no reflective insulation benefit.
Reflectix 4 ft.
Our double bubble products are ideal for metal buildings where the control of condensation is necessary.
The ability to stop heat transfer.
Any additional r value is achieved by the use of dead air spaces around the reflective product or in used in conjunction with other mass insulation products like fiberglass foam etc.
R values depend on application.
Double bubble insulation is the most effective bubble insulation with highest r value.
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.
Double reflective insulation bp48025 48 x 25 100 sq.
Some products say r4 r6 or r8.
Thd sku 469837.
Double reflective insulation bp48100 48 x 100 400 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.
With multiple layers of product and airspaces between each layer enhanced performance will be gained.
No mess no itchy fibers.
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.
An r 1 1 is provided from the product itself for the reflective double bubble material.
Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own.
Class a class 1 fire rating.
A comparable roll of reflective insulation cost 43 cents per square foot at the same location.
Air space equals r value.
Are two layers of polyethylene industrialized air bubbles bonded between exterior.
All our reflective double bubble products.
The reflectix double reflective insulation is the most versatile widely distributed energy efficient product that we manufacture.
