Our Revolutionary Heat Trapping Design Saves Energy. The exclusive AccuLok™ hot tub cover design traps escaping heat, minimizing heat loss and saving operating costs. A full 7" no-gap heat shield hem seamlessly surrounds the spa, with 4 locking tiedown straps sewn on the outside of the hem holds it in place and tight to the spa cabinet. Traditional cover design has a loose hem design allowing heat to escape and outside air and wind to enter the hot tub increasing energy usage. An insulating pillow the full length of the folding hinge section further prevents heat escape. A thermal imaging camera was used by an independent testing center as shown here Extensive heat loss is indicated by the bright orange spots. It is obvious the seamless heat shield and revolutionary hem design of the AccuLok cover as compared to the traditional design offers significant heat trapping features.
