The foam insulation thickness of a spa cover is crucial for maintaining heat retention and energy efficiency. A thicker foam provides better insulation, reducing heat loss and saving energy costs. Typically, spa covers range from 4 to 6 inches in thickness. The 84" x 84" Cover for Getaway Spas and the 83" x 70" Hot Tub Cover both feature a 6-inch thick foam that tapers to 4 inches, offering excellent insulation.
