ThermoFloat Spa Blankets are one of the best little investments any hot tub owner can make. These advanced floating covers very quickly pay for themselves by conserving heat in three ways:
Reduces heat loss due to evaporation by up to 95%
Provides a layer of insulation in addition to your spa cover
Helps prevent spa cover water absorption
Extends Spa Cover Life
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 and loss of R-Value.
The advanced Thermo-Tex material is chemical resistant and designed to lay flat on the hot tub water surface for maximum effectiveness.
Product notes: Easily trimmed to fit any spa shape. One-year warranty.
