BigXwell Solar Pool Cover — 12 mil Round 12 ft Solar Blanket for Above-Ground & In-Ground Pools, Bubble-Insulated UV-Treated

BigXwell's 12 mil round solar pool cover is a durable, bubble-insulated blanket that captures sunlight to warm your pool, reduce evaporation, and help retain heat day and night.

Whether you own an above-ground or in-ground round pool, this 12-foot, 12-mil solar blanket from BigXwell is built to extend swim seasons and lower water and heating losses. Made from UV-treated polyethylene with thousands of thermal bubbles, the cover converts and holds solar energy while remaining light enough for quick removal and trimming to size. It’s designed to be an affordable, low-maintenance way to keep pool temperatures steadier and reduce chemical and water top-ups.

How does the BigXwell solar cover warm my pool?

The cover’s bubble layer captures solar radiation at the water surface and reduces heat escape after sunset. By creating a thin insulating barrier, it limits convection and radiant heat loss so water temperature stays higher for longer. Results depend on sunlight, ambient temperature, and pool size, but many owners see noticeable temperature gains on sunny days.

• 12 mil thickness for improved insulation compared with thinner blankets
• Thousands of air pockets convert sunlight into heat at the surface
• Reduces overnight heat loss so daytime gains are preserved
• Works best under direct sunlight and with full surface coverage

Will this cover reduce water evaporation and chemical use?

Yes — the BigXwell solar blanket substantially lowers evaporation by forming a surface barrier, which keeps water and dissolved chemicals from escaping into the air. Less evaporation also means fewer chemical top-ups and reduced need to refill the pool, saving both water and upkeep costs. Properly covering the pool whenever it’s idle yields the best savings.

• Minimizes water loss by up to around 95% compared with an uncovered pool
• Helps maintain chemical balance longer between treatments
• Reduces frequency of refilling and associated water cost
• Lightweight cover makes frequent use practical and convenient

Can I fit this cover to my pool and how long will it last?

The material is flexible and can be trimmed with scissors to match round pools or to adapt to slightly irregular edges. Constructed from UV-stable polyethylene, the 12 mil thickness balances durability and ease of handling; it resists everyday wear from sun exposure and routine handling. Lifespan varies by climate and care, but gentle storage and avoiding sharp objects will prolong service.

• Trim-to-fit design for above-ground and inground pools
• 12 mil PE material offers enhanced tear resistance versus thinner covers
• Lightweight for quick installation and removal
• Store flat and out of direct sun when not in use to extend life

How do I use and care for the solar blanket?

Lay the blanket bubble-side down on the water so the bubbles contact the surface and capture heat. Remove debris before covering and rinse the cover occasionally to prevent buildup; dry and fold it when storing. Avoid dragging across rough surfaces and trim carefully if resizing to maintain even coverage.

• Place bubble side down on calm water for best heat transfer
• Rinse with fresh water and air-dry before long-term storage
• Trim with sharp scissors for a precise fit along the pool rim
• Handle gently—avoid sharp edges and chemical spills

Who is this for: The BigXwell 12-foot, 12 mil solar pool cover is ideal for pool owners who want an economical way to warm water, cut evaporation, and lower maintenance time. It suits both above-ground and in-ground round pools, homeowners who prefer a lightweight, trim-to-fit option, and anyone looking to extend their swim season without installing mechanical heaters. If you need a simple, effective blanket to retain heat and reduce water and chemical loss, this solar cover is a practical choice.
