You should keep two things in mind when looking for a new hot tub cover: the location and your environment. If you keep your spa hot year round, you will want a spa cover that will minimize your heating bills, particularly if you live in a cold climate. Consider the levels of sun, cold, rain, wet snow and snow your hot tub cover will receive. Each of these aspects should impact what sort of hot tub cover you get, and what options you should decide on when purchasing one to make sure you get the best cover possible.

It’s frequently misunderstood that the density of the covers foam cores is the most important factor for keeping your heating bill low. Actually, this isn’t completely true. It is a far more important factor to increase the thickness of the foam core in the hot tub cover. This is due to the way the insulation value, or R-value is calculated. This value is found if you take the insulating value of the foam and multiplying it by the cover’s thickness. The value increases for a thicker cover with denser foam.

If you are indeed replacing your hot tub cover because your current cover is water logged and weighs a ton, be sure the cover you select has the best water logging protection available. In the industry, the water logging protection component of the cover is called the vapor barrier. It’s referred to as the vapor barrier since heavy steam from the hot water is what will eventually penetrate the cover, rendering it heavy. Though many people believe it’s designed to keep rain and snow out of the cover, this is not true.
