Reflective foil insulation r value.

No mess no itchy fibers. The stated r value is only valid for the application specified when installed per the installation instructions on the label or at our website. Reflectix 4 ft. Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own.

What about r values for a reflective insulation and why do they vary with application. Styrofoam or eps expanded polystyrene has an r value of 3 85 per inch. This is a great real life example of why we don t make coffee cups out of wood styrofoam keeps the heat in longer. Heat flow direction 2.

Reflective insulation and radiant barriers that are safe easy to install and thermodynamically efficient for new building construction. This might surprise you but radiant barrier foil on its own has no r value. An r value is a measure of an insulation product s resistance to thermal heat transfer. Each of reflectix s statements about r value on the label is valid but they must be accompanied by a reading of the finer print off to the side.

Class a class 1 fire rating. The r values of reflective insulation and mass insulation are based on the same fundamental equation. Thd sku 884247. Therefore three inches of styrofoam will have an r value of over 11.

Double reflective insulation r values range from r 3 7 to r 17. 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 inner substance trapped airspaces. The ability to stop heat transfer. R values depend on application.

Provides innovative and cost effective insulation solutions. This is a reflective insulation the label reads. 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. It s a measure of how long it takes a heat absorbing product to absorb 100 of its potential and begin to transfer that heat out the other side of the product.

R values for reflective insulations are dependent on two primary criteria. R3 0 3 r3 5 8 brand. The amount of air space in a closed cavity on the reflective side of the product in a building assemblage.
