VEVOR Solar Pool Cover 36 x 18 ft Rectangle — 8 mil Bubble PE, Heat Absorbing & Retaining

VEVOR's 36 x 18 ft 8 mil solar pool cover is a bubble-style thermal blanket that raises daytime water temperature and reduces overnight heat loss for rectangular pools.

This heavy-duty PE solar blanket uses micro-bubble solar-heat technology to trap warmth, limit evaporation and reduce chemical loss so you spend less time heating and maintaining your pool. Designed to be trimmed for a custom fit, the 36 x 18 ft sheet fits many rectangular and large rectangular-style pools, for both inground and above-ground installations. With a balance of durability and flexible performance, it extends swim seasons while cutting water and energy use.

How does this cover warm my pool during the day?

The cover’s 8 mil thickness and bubble surface capture and concentrate sunlight on the pool surface, converting light into stored heat. Micro-bubbles act like miniature solar panels, increasing absorption and warming the top layer of water more quickly than an uncovered pool. It’s most effective in sunny conditions and when used consistently during daytime hours.

• 8 mil bubble construction for efficient solar absorption
• Micro-bubble texture increases surface-area heat intake
• Works best on sunny days to accelerate temperature gain
• Trim-to-fit design allows close contact with pool edges

Will it prevent heat loss and evaporation at night?

Yes — the blanket forms a thermal barrier that reduces radiative and convective heat loss after sunset, helping to keep water warmer overnight. It also substantially reduces surface evaporation, which conserves both water and dissolved pool chemicals. Stored heat from the day is retained longer, reducing reliance on mechanical heaters.

• Reduces heat loss by trapping warm surface water heat
• Helps cut water evaporation by up to 95%
• Slows chemical dissipation to reduce maintenance frequency
• Compatible with passive heating to lower energy bills

Is this cover durable and safe for outdoor use?

The sheet is made from robust polyethylene designed to resist stretching, ripping and UV aging under normal pool conditions. It holds up well to routine sun exposure but should be removed or stored in excessively chlorinated or highly acidic conditions to extend service life. While not intended as a safety cover, it is sturdy enough for seasonal outdoor use and frequent handling.

• PE material resists tearing and UV degradation
• 8 mil thickness balances flexibility and strength
• Avoid prolonged exposure to extremely high chlorine or acid
• Not a substitute for a dedicated safety cover

How do I fit and care for this 36 x 18 ft solar blanket?

The blanket ships oversized for trimming—simply cut to match your pool’s shape with scissors or a utility knife. Light cleaning and drying before storage prolongs lifespan; store rolled or flat in a cool, shaded place when not in use. Routine checks for nicks and edge wear will help maintain performance season after season.

• Trim to fit irregular pool shapes with scissors or a utility knife
• Rinse and air-dry before folding or rolling for storage
• Inspect edges and repair small tears promptly
• Store away from sharp objects and strong chemicals

Who is this for: The VEVOR 36 x 18 ft solar pool cover is ideal for pool owners who want an economical, easy-to-use way to raise water temperature, reduce evaporation and lower heating costs. It's well suited to homeowners with rectangular inground or above-ground pools who value simple maintenance, seasonal extension of swim time, and greater water conservation without installing complex equipment.
