Blue Wave 12-mil Solar Blanket for Rectangular Pools, 12' x 24' — Blue, heats water & reduces evaporation

The Blue Wave NS405 12-mil 12' x 24' rectangular solar blanket is a lightweight, bubble-style pool cover that captures sunlight to warm water, reduce evaporation, and block debris for both inground and above-ground pools.

Designed for pool owners who want more usable swim days without installing heaters, this 12-mil solar cover uses thousands of air-filled thermal bubbles to transfer solar energy into your water and slow nightly heat loss. The blue sheet lies directly on the water, is easy to place and remove, and can be trimmed with household scissors to accommodate ladders and fittings. Backed by Blue Wave’s 5-year limited warranty, the NS405 is a simple, low-maintenance way to extend your season.

How does this solar blanket actually warm the pool?

The blanket’s underside contains tightly packed, downward-facing bubbles that act like miniature collectors and insulators. During sunny hours the bubbles absorb and transfer heat into the water; at night they form an insulating barrier that reduces heat escape.

• Thousands of air-filled thermal bubbles collect solar energy and move heat into the water.
• Blue surface color helps capture and retain daytime warmth.
• Insulating bubble layer slows overnight cooling to keep temperatures steadier.

Will it fit my rectangular 12' x 24' pool and how do I handle obstacles?

The NS405 is sized to cover standard 12 by 24-foot rectangular pools and is simple to modify for pool ladders or skimmers. Its 12-mil thickness balances durability with lightweight handling so one person can position it, and you can trim away excess material with scissors when needed.

• Pre-cut 12' x 24' rectangle size for common pools—ready to use out of the box.
• Easily trimmed with household scissors for ladders, steps, and returns.
• Thin enough for manageable rolling and storage, thick enough for everyday wear.

How does it help with maintenance and water loss?

Beyond heating, the blanket reduces water evaporation and keeps leaves and dirt from entering the pool, which lowers top-offs and cleaning frequency. The cover floats directly on the surface creating a physical barrier that limits debris accumulation and evaporation during both day and night.

• Reduces evaporation to conserve water and chemicals between uses.
• Blocks leaves, dirt, and airborne debris to cut down skimming and filter runs.
• Helps maintain chemical balance by reducing dilution from refills.

What are the care and storage recommendations for the NS405?

Proper handling extends the blanket’s service life: rinse, dry, roll rather than fold, and store in shade when not in use. Avoid leaving it exposed to strong sun unattended for long stretches and remove it during heavy storms or when sharp objects are present.

• Rinse and let dry before long-term storage to prevent mildew.
• Roll the cover to avoid creases and make deployment quicker.
• Store in shaded area and away from pool chemicals that could degrade material.

Who is this for? The Blue Wave NS405 12-mil solar blanket is ideal for families and homeowners with 12' x 24' rectangular pools who want an affordable, low-effort way to warm water, reduce evaporation, and keep debris out. It suits users who value straightforward installation, occasional trimming for accessories, and a product backed by decades of pool industry experience and a 5-year limited warranty.
