7x7 ft Hot Tub Solar Cover 16 Mil Bubble Heat Retention Blanket

Built for Everyday Heat Retention

This 7x7 ft thermal blanket uses a 16 mil polyethylene film with an integrated bubble layer that sits directly on the water surface. The bubble structure forms a consistent barrier that reduces evaporation and slows heat transfer. The material resists tearing under typical handling conditions. Its square format fits standard spa layouts while remaining flexible for trimming. The floating design stays level without added supports.

Floating Thermal Layer Design

The cover operates by resting bubble side down against the water, forming a sealed contact layer. Sunlight passes through the clear PE film and warms the water beneath during daytime exposure. At night, the same layer helps limit heat loss by reducing surface evaporation. The 7x7 ft size covers most square hot tubs and small pools. Users can cut the sheet with scissors to match custom dimensions or rounded corners.

Quick Water Surface Placement

Daily use involves placing the cover flat across the water surface and removing it before use. The compact PE sheet can be folded or rolled for storage when not in use. Cleaning involves rinsing or laying it flat under sunlight to dry. The flexible material allows simple handling without rigid frames or attachments. Its compact form fits shelves or storage bins when folded. The simple layout supports quick setup and removal.
