Heat and Moisture Retention
Aside from keeping debris out of your hot tub, a primary purpose of a hot tub cover is to hold in heat and moisture. The materials that a hot tub cover is made from, along with a good fit, will assist in preventing heat loss and evaporation. To evaluate the heat and moisture retention abilities of a replacement hot tub cover, consider how thick the cover is—keeping in mind that most covers are tapered. Also pay attention to the density of the foam inside the cover, which is expressed in pounds. The foam used for hot tub covers usually ranges from a 1-pound to 2-pound density; the denser the foam, the better the insulation of the hot tub cover.
Extra Features
Additional options can enhance the usefulness, longevity, or safety of your hot tub cover. Most covers include tie-down straps to secure the cover, but some hot tub covers can also be ordered with safety locks to prevent the removal of the cover without a key. Since a hot tub cover is exposed to the elements, look for UV-resistant vinyl as well as an inside vapor barrier that protects the hot tub cover from becoming waterlogged. Some hot tub cover manufacturers offer the option for a double vapor barrier to provide additional protection against moisture.
