Angooni Hot Tub Solar Bubble Blanket 7 x 7 ft — 16‑mil Insulating Cover, Trims to Fit

This heavy-duty square bubble cover is made for hot tubs, small spas, and stock tanks that need dependable insulating protection. With thicker 16-mil material and molded air cells, the blanket traps solar energy and reduces water loss while blocking debris. It’s easy to trim for a tailored fit and is meant to sit bubble-side down for best heat transfer.

How does this cover reduce heat loss and evaporation?

The Angooni blanket forms a floating thermal layer that limits direct air exposure to the water surface, slowing heat escape and evaporation. Its bubble cells create insulating pockets of air that capture sunlight and transfer warmth into the water, which helps maintain temperature with less heater runtime.

• 16-mil thickness provides stronger insulation than common 8–12 mil covers
• Molded bubbles trap and transfer solar heat into the water
• Reduces water evaporation by up to 95% when properly installed
• Helps lower energy use by shortening heater cycles

Will it keep leaves and dirt out of my spa?

The blanket provides a simple barrier that prevents most floating debris from reaching the water between uses, cutting down on scrubbing and filter cleaning. While it blocks leaves, dust, and small objects, it is not an airtight lid—regular maintenance and skimming remain recommended.

• Blocks leaves, pollen, and surface dust
• Deters small animals from entering the water
• Reduces frequency of filter backwash and surface skimming

How easy is it to fit and trim for my hot tub?

The cover comes in a square 7 x 7 ft sheet that’s simple to cut with household scissors to match irregular shapes or to remove excess. For best results, align the bubbles facing down toward the water and trim slowly for a neat fit; you can tuck trimmed edges into the tub lip if needed.

• Pre-sized 7 x 7 ft panel, ready to customize
• Scissors or utility knife will trim the material cleanly
• Bubble side must face down for optimal heat transfer

How durable is the material and will it tear easily?

The 16-mil polyethylene construction is thicker than many market alternatives and resists punctures and bubble rupture better than thinner covers. While durable, the blanket should still be handled with care around sharp edges and secured when not in use to prolong lifespan.

• 16-mil thickness increases tear resistance
• Less prone to bubble collapse compared with 8–12 mil sheets
• Store flat or rolled, away from direct sun when unused to extend life
