Blue Wave 12x18 ft Oval Solar Pool Cover 8‑Mil Blue — Thermal Bubble Blanket for Heat Retention & Reduced Evaporation

Blue Wave's 12x18-ft oval 8-mil solar pool cover is a lightweight thermal bubble blanket that captures solar energy to help warm above-ground pools and reduce evaporation.

Designed for 12 x 18 foot oval above-ground pools, this Blue Wave solar blanket rests on the water surface to absorb sunlight and slow overnight heat loss. Constructed with thousands of air-filled thermal bubbles and an 8-mil thickness, it balances durability with easy handling so you can place and remove the cover without bulky equipment. The blue sheet also acts as a simple debris barrier, cutting down on leaves and dirt between uses.

How much warmer can my pool get with this cover?

On sunny days the insulating bubbles concentrate and transfer solar heat directly into the water, producing a noticeable rise in temperature. While results vary by climate and sunlight, Blue Wave reports temperature increases up to about 15°F under favorable conditions.

• 8‑mil thickness holds heat while remaining light to handle
• Thermal bubble pattern maximizes surface contact with water
• Best performance on clear, sunny days with direct sunlight
• Temperature gains depend on pool size, sun exposure, and air temperature

Will this cover reduce water evaporation and maintenance?

Yes—by covering the surface, the blanket slows evaporation and helps keep debris out of the pool. That lowers the need to top off water and reduces the amount of skimming and filter cleaning between swims.

• Surface coverage cuts evaporation compared to an uncovered pool
• Acts as a physical barrier against leaves, dirt, and airborne grit
• Helps preserve pool chemicals by limiting exposure to sun and air

How do I fit, store, and care for the cover?

The cover ships to fit a 12 x 18 ft oval pool and can be trimmed with household scissors to accommodate ladders or rails. Roll it rather than fold for storage, keep it in the shade when not in use, and ensure it is dry before long-term stowage to prolong life.

• Trim with scissors for ladders and obstacles
• Roll cover to avoid creases; store in shaded area
• Dry fully before storing to prevent degradation and mildew
• Avoid leaving heavy debris or prolonged rooftop exposure

How durable is the Blue Wave 8-mil material and what warranty is included?

The blanket is manufactured with UV protection to withstand routine outdoor exposure and an 8-mil gauge that balances toughness and ease of use. Blue Wave supports the product with a 3-year limited warranty and leverages more than three decades of pool-industry experience.

• UV‑protected material designed for seasonal outdoor use
• 8-mil thickness resists punctures better than thinner covers
• 3-year limited manufacturer warranty from Blue Wave

Who is this for: The Blue Wave 12x18-ft oval 8-mil solar pool cover is aimed at above-ground pool owners who want a low-effort way to raise water temperature, cut evaporation, and reduce cleanup time without installing heaters or complex systems. It suits seasonal swimmers, families with smaller oval pools, and anyone seeking an economical, portable thermal blanket backed by a multi-year warranty.
