The R Factor for Insulation Doesn’t Measure Radiant Heat Transfer – Yikes!

Measuring the R factor of insulation is not adequate when it comes to judging how effective it will be in blocking all types of heat transfer and lowering energy bills. The R factor measures insulation’s ability to resist heat transfer by conduction, which is heat transfer through contact between solid objects. It also measures convection, which is heat transfer between object through air circulation. However, it does not measure the ability to block emission, which is heat transfer directly from a radiant source, the most common way homes lose energy.

Unlike R factor, the E factor does measure how effective insulation is at preventing radiant heat transfer. eShield™ insulation has the highest E value on the market today, featuring the same ground-breaking multilayer technology used to insulate NASA spacesuits. It is able to block 97% of all emission and it has a permeability rating of 13, meaning it will not cause mildew or other damage due to moisture.

Adding eShield™ to existing wall, ceiling, attic, floor, and basement insulation with an R factor that blocks high amounts of conduction and convection will help turn any home into a fortress of energy conservation and efficiency.  eShield™ is guaranteed to result in savings of at least 25% on energy bills.
