Reflective Foil Insulation R Value

Provides innovative and cost effective insulation solutions.

Reflective foil insulation r value.

Therefore three inches of styrofoam will have an r value of over 11. Most people are familiar with the term r value when discussing insulation properties. This is a great real life example of why we don t make coffee cups out of wood styrofoam keeps the heat in longer. Thd sku 884247.

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. 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. This is a reflective insulation the label reads.

An r value is a measure of an insulation product s resistance to thermal heat transfer. 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.

Double reflective insulation roll with staple tab edge model st16100 56 47 roll 56 47 roll free delivery. R values for reflective insulations are dependent on two primary criteria. From our modern facility with the highest production capacity in the industry you can expect quality reflective insulation and radiant barrier products and quick order fulfillment. R3 0 3 r3 5 8 brand.

Styrofoam or eps expanded polystyrene has an r value of 3 85 per inch. Any bubble insulation that is approximately thick can only achieve an average r value of 1 to 1 5 on its own. The amount of air space in a closed cavity on the reflective side of the product in a building assemblage. The r values of reflective insulation and mass insulation are based on the same fundamental equation.

Reflective insulation and radiant barriers that are safe easy to install and thermodynamically efficient for new building construction. Double reflective insulation r values range from r 3 7 to r 17. Heat flow direction 2. Reflectix 4 ft.

This might surprise you but radiant barrier foil on its own has no r value. Class a class 1 fire rating. 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.
