ONLY Acculok hot tub covers feature a unique layer of water vapor barrier. Years of scientific research have resulted in a cover that has 400% more resistance to water vapor absorption than any other hot tub cover on the market.
Our unique design is proven to save significant dollars in heating costs. The seamless extra long shield prevents heat from escaping the hinge section, where significant heat is lost on standard hot tub covers.
