Once again, insulation is the name of the game. Common sense says that the heat rises - that is why Arctic Spas makes the thickest cover in the spa industry. Don't fall for imitations. Arctic Spas' Polar Covers are designed for those who really want the best insulation available. The 5" to 4" tapered Polar cover eliminates large heat loss problems found on other manufacturers' covers.
Structurally reinforced, all our covers are capable of supporting the weight of a heavy snow fall. As an extra feature we add an insulating baffle between the cover halves to prevent heat loss along the seam.
The interior cover skin is made of swimming pool grade, vulcanized vinyl with reflective qualities to lock in the heat and repel the moisture. The exterior is marine grade vinyl, able to withstand the harshest climates. Locking straps secure your spa cover against wind and protect small children from entering unsupervised.
