Buying guide

What to look for

Assessing Material Thickness

When selecting a solar cover for your 18x36 pool, the thickness, measured in mils, is a primary indicator of durability and heat retention. A 16mil cover, such as our best overall pick, is generally thicker and more robust than a 12mil option. Thicker covers tend to be more effective at insulating the water and resisting wear from UV exposure. However, they are also heavier and may be more challenging to maneuver. Consider your physical ability to handle the cover and whether you will be using a reel system. If you prefer a lightweight option that is easier to manage, a 12mil cover may be more suitable, despite offering slightly less insulation than its thicker counterparts.

Verifying Pool Dimensions

Accurate measurement of your pool is essential before purchasing. While these covers are listed as 18x36, verify your pool's actual dimensions to ensure a proper fit. If your pool has rounded corners, stairs, or unique shapes, you may need to trim the cover to fit. Always check the manufacturer's guidelines regarding trimming, as some materials are easier to cut than others. A cover that is too large can be cumbersome, while one that is too small will fail to provide adequate coverage, leaving gaps where heat can escape and debris can enter. Measure your water surface carefully and compare it against the provided dimensions to ensure the best possible coverage for your specific pool configuration.

Evaluating Reel Compatibility

Think about how you plan to deploy your 18x36 solar cover. If you intend to use a reel system, ensure the cover material is compatible with the reel's attachment method. Some covers come with pre-attached grommets or specific reinforcement strips that make installation easier. If you are manually removing the cover, consider the weight of the material. A heavy 16mil cover might be difficult to manage without a reel. Check the product specifications for details on weight and handling recommendations. Investing in a quality reel system can significantly improve your daily experience, making it much easier to uncover and cover your pool, which encourages more frequent use and better maintenance.
