Q: Why don’t building codes specify E-values as well as R-values?

A: In the last century, the only cost-effective insulation for the home was mass insulation like fiberglass, cellulose and foam that reduced heat transfer by convection and conduction. The “R-value” was the measure of how good a job those insulators did. Yet R-value measures only the smallest part of residential heat transfer. E-value is the measure of emissive, radiant heat transfer, the principle source of energy loss. New technologies make it practical to achieve extremely low emissive in window glass and in a reflective film ideal for the attic. As these low-E technologies advance, the codes will catch up and E-value will replace R-value as the primary measure of energy efficiency.

Q: Will eShield™ installed in my attic trap mildew-causing moisture in my ceiling?

A: eShield™ is perforated to allow vapor to escape the housing envelope – it will not contribute to mildew growth in your home.

Q: Will eShield™ create a fire hazard in my attic?

A: eShield™ Attic Energy Barrier is fire-resistant – it’s less combustible than the structure to which it attaches. Of course, like almost any material, it will melt and eventually burn if exposed to an open flame.

Q: Can I get a rebate for installing eShield™?

A: eShield™ Attic Energy Barrier is Department of Energy approved and bears the Energystar® mark. This is the gold standard in energy efficiency and qualifies for most federal, state and energy company rebates. Check with your eShield™ rep to learn what’s available in your area.
