Double reflective insulation r value.

If you install 2 layers of a reflective insulation does the r value double. 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. Thd sku 469837. 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.

Double bubble insulation is the most effective bubble insulation with highest r value. Some products say r4 r6 or r8. 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.

Though exact prices will vary by store and region this price ratio is fairly consistent meaning you. The rubber meets the road on reflectix s website where it says no air space no reflective insulation benefit. Our double bubble products are ideal for metal buildings where the control of condensation is necessary. The reflectix double reflective insulation is the most versatile widely distributed energy efficient product that we manufacture.

Double reflective insulation r values range from r 3 7 to r 17. No mess no itchy fibers. The r values of reflective insulation and mass insulation are based on the same fundamental equation. 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.

Class a class 1 fire rating. 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. An r 1 1 is provided from the product itself for the reflective double bubble material. Double reflective insulation bp48025 48 x 25 100 sq.

Reflectix 4 ft. R values depend on application. If you don t provide air space this product provides almost no insulating value. Are two layers of polyethylene industrialized air bubbles bonded between exterior.

The ability to stop heat transfer.
