Double Reflective Insulation R Value

Double reflective insulation bp48100 48 x 100 400 sq.

Double reflective insulation r value.

A comparable roll of reflective insulation cost 43 cents per square foot at the same location. 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 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.

Class a class 1 fire rating. Some products say r4 r6 or r8. Thd sku 469837. Our double bubble products are ideal for metal buildings where the control of condensation is necessary.

An r 1 1 is provided from the product itself for the reflective double bubble material. Double bubble insulation is the most effective bubble insulation with highest r value. The ability to stop heat transfer. Double reflective insulation r values range from r 3 7 to r 17.

Double reflective insulation bp48025 48 x 25 100 sq. With multiple layers of product and airspaces between each layer enhanced performance will be gained. R values depend on application. Are two layers of polyethylene industrialized air bubbles bonded between exterior.
