Features to Consider when Buying a Polar Cool Cover

The best solar pool covers are those that fit your requirements and meet your needs. In order to make an informed decision when purchasing a solar blanket, keep the following features in mind.

Type of Solar Pool Cover

While the traditional bubble cover is the one that comes to mind when thinking of solar pool covers, it’s far from the only type of cover on the market today. Other options include solar rings and liquid solar covers.

Bubble Solar Pool Covers

These are the most common solar pool covers used and look like large sheets covered with bubbles. They’re more efficient than solar rings because they cover pools entirely. They also keep pools safe from leaves and debris.

Solar Sun Rings

These are disks that float in pools to keep them warm. Because these are smaller than traditional covers, they’re easy and convenient to use. That being said, they leave open spaces between them. You often need multiple rings to fill larger pools.

Liquid Solar Covers

Liquid solar covers are additives that create a film on the surface and use a chemical reaction to heat pools and prevent water evaporation. However, it should be noted that they break down over time, need to be re-added, and don’t provide any protection against debris falling into the pool. Additionally, they can only be used in chlorine-free pools.


Most solar pool covers are clear, black, and blue. Because darker colors are known for trapping more heat than lighter colors, it’s best to choose darker shades for use at night or if you’re live in an area with little sunlight. Clear covers are excellent for areas with plenty of sunshine and ensure that the water doesn’t get too hot. Opting for a light blue color is common since this is seen as the best of both worlds.


The thicker the solar pool cover, the better the insulation. That being said, thicker covers are also heavier and may not be as convenient to use. Thickness is measured in mil, with covers available in 8-, 10-, 12-, 14, and 16-mils. For maximum insulation, opt for 14-mil or 16-mil covers. If you prefer something more lightweight, 10-mil and 12-mil covers are excellent options.

Shape and Size

The solar pool cover you select has to fit the shape and size of your pool so it covers the entire area without difficulty. When in doubt, select a larger size since it’s easier to tailor the fit than to return the cover and order a new one.
