Double Reflective Insulation R Value

Double reflective insulation r values range from r 3 7 to r 17.

Double reflective insulation r value.

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. Double reflective insulation bp48100 48 x 100 400 sq. With multiple layers of product and airspaces between each layer enhanced performance will be gained. R values depend on application.

The r values of reflective insulation and mass insulation are based on the same fundamental equation. Some products say r4 r6 or r8. No mess no itchy fibers. Reflectix 4 ft.

Are two layers of polyethylene industrialized air bubbles bonded between exterior. All our reflective double bubble products. Double reflective insulation bp48025 48 x 25 100 sq. The reflectix double reflective insulation is the most versatile widely distributed energy efficient product that we manufacture.

The ability to stop heat transfer. Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own. Air space equals 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 you install 2 layers of a reflective insulation does the r value double. 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. Thd sku 469837. Double bubble insulation is the most effective bubble insulation with highest r 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. Our double bubble products are ideal for metal buildings where the control of condensation is necessary. Though exact prices will vary by store and region this price ratio is fairly consistent meaning you. 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.
