Energy Saver Package

DuraTherm Energy Saver Package Take spa cover energy savings to the max: Energy Shield reflects up to 95% of radiant heat back into the spa water. Hinge Thermal Seal insulates to impede rising heat loss. Energy Shield Like a survival blanket, a reflective layer under the core vapor barrier increases energy efficiency by redirecting radiant heat back into the spa water. Hinge Thermal Seal Like a pillow between the two halves of the spa cover, this sealing insulation barrier virtually eliminates rising heat lost through the hinge.
