Pays for itself by cutting spa power consumption. Reduces evaporation by
up to 95%-- a primary cause of heat loss. Provides a layer of insulation
in addition to your spa cover.
Easily trimmed with scissors for a great fit for any spa.
By keeping hot tub surface evaporation to a minimum, less moisture and chemicals will come in contact with your spa cover's underside, prolonging its longevity and helping to prevent water-logging, the leading cause of cover failure.
