Buying Guide: Choosing The Right 18′ Round Solar Cover
- Mil thickness matters: Heavier mil (12–16) provides stronger durability and heat retention, ideal for year-round or windy climates. Lighter mil (6–8) offers easier handling and is suitable for casual use or shorter seasons.
- Heat retention vs. evaporation reduction: Consider whether your primary goal is warming the water quickly or conserving water and chemicals. Some covers emphasize both, while others focus on one benefit.
- Pool type and compatibility: Ensure the cover fits an 18′ round pool and matches your pool type (above ground vs. in-ground). Some designs are better suited for specific frame systems.
- Handling and maintenance: Heavier covers may require reels or assistance for safe placement. Lightweight options are easier for single-person use but can be less durable over time.
- Durability features: Look for reinforced seams and wide seams, which improve tear resistance and seasonal longevity. UV resistance and bubble distribution affect heat transfer.
