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 or 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 emissivity, radiant heat transfer, the principle source of energy loss. New technologies make it practical to achieve extremely low emisssivity 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 with 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 peforated 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 for prolonged periods.
Q: Can I get a rebate or Tax Credit for installing eShield?
A: eShield Attic Energy Barrier is Department of Energy approved and bears the Energy Star Logo. This is the gold standard in energy efficiency and qualifies for most federal, state and energy company rebates. Call DuraMAX to find out what's available in your area.
