Insulated hot tub insulation  keep the water at a consistent temperature and are much more energy efficient than non-insulated tubs. The insulation also helps to reduce noise levels from the water and the surrounding area. This means that insulated tubs are more comfortable to use and cost less to run than uninsulated tubs.

Insulation varies by type and density, with higher densities offering greater insulation value. Foam insulation typically consists of polyurethane and is either rigid (boards) or sprayed in. Spray foam is a popular choice because it can be installed quickly and easily, and it is relatively inexpensive compared to other types of insulation.

Sealing in the Heat: The Importance of Hot Tub Insulation for Energy Efficiency

Another option is to insulate a hot tub with a thermal wrap. These wraps are similar to those used to insulate refrigerators, and they do offer some heat retention. However, the insulating material in these wraps will fill with water and lose its effectiveness. This is why it is important to maintain the integrity of your hot tub cover and to repair any leaks as soon as they appear.

Full foam or foam filled insulation is another great way to insulate your hot tub. This is achieved by sprayed or poured foam that completely envelops the shell and all components in your spa. This is the highest level of insulation available and will keep your hot tub water warmer for longer, save you money on energy bills, and provide your shell and equipment with the absolute best possible protection against leaks and other damage.
