Double Reflective Insulation R Value

All our reflective double bubble products.

Double reflective insulation r value.

Double bubble insulation is the most effective bubble insulation with highest r value. Reflectix 4 ft. 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 r values range from r 3 7 to r 17.

The r values of reflective insulation and mass insulation are based on the same fundamental equation. Double reflective insulation bp48100 48 x 100 400 sq. Double reflective insulation bp48025 48 x 25 100 sq. Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own.

R values depend on application. Some products say r4 r6 or r8. 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. 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.

No mess no itchy fibers. Class a class 1 fire rating. Air space equals r value. Though exact prices will vary by store and region this price ratio is fairly consistent meaning you.

Our double bubble products are ideal for metal buildings where the control of condensation is necessary. 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. The ability to stop heat transfer.

Are two layers of polyethylene industrialized air bubbles bonded between exterior. If you install 2 layers of a reflective insulation does the r value double. 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.

The reflectix double reflective insulation is the most versatile widely distributed energy efficient product that we manufacture.
