• Provides a layer of insulation in addition to your spa cover Helps prevent spa cover water absorption Extends life of hard spa cover  
• 400 micron
• By keeping hot tub surface evaporation to a minimum, less moisture and chemicals will come in contact with the underside of your hard spa cover, prolonging its longevity and helping to prevent water-logging, the leading cause of cover failure.
• The Thermal Blanket is 7ft. square and can be easily trimmed to fit any spa shape.
• The blanket should be laid bubble side down onto your hot tub water for maximum effectiveness.
• The cover works by sunlight heating the air that is trapped within the small bubbles, this heat is then transferred to the water. The cover also traps heat in the hot tub so the water will retain heat for longer, and prevents evaporation of water and chemicals.
• The advanced Thermo-Bubble material is chemical resistant and designed to lay flat on the hot tub water surface for maximum effectiveness.
