ReflecTech Energy Shield - add $59.00

Our newest upgrade! By adding a sheet of EPS foam that is laminated on both sides with reflective foil to the main foam core we are creating a system that will reflect the energy rising off of your spa back down and the cold creeping in from above back up. This breakthrough technology is added inside the vapor barrier to protect from the delamination issues that arise from the use of reflective laminate fabric found in inferior spa covers with a similar feature.
