A thermal hot tub cover keeps the heat in and the cold air out, allowing for a more efficient use of energy by your spa’s heater. This also helps to prevent the loss of heat from evaporation and can save you money on your energy bill, as well as help protect your investment in your hot tub and extend its lifespan.

In addition, a good hot tub thermal hot tub cover can prevent leaves and other debris from falling into the water as well as keep animals out, extending the life of your tub and helping to maintain the chemical balance in it. A cover can also protect the foam core from mildew and bacteria. A foul smell is a sure sign that your hot tub cover needs to be replaced, as mildew and bacteria can grow unchecked in the small airspaces of an old, dirty foam core.

When it comes to choosing a new cover, there are many options to choose from. Some are sturdier than others and provide different levels of insulation. The R-Value is an important factor to consider, as it can help determine how much energy will be saved by the cover.

We recommend choosing a cover that is double-wrapped with polyethylene sheeting for a superior vapor barrier and increased moisture resistance. Having a 4-inch or thicker foam core is also important, as this can add more insulation to the cover. Lastly, remember that a hard cover will be heavier than a soft cover, however, a good hot tub cover lifter can make it easier to remove and replace the cover.
