What is Solar Cover Mil Thickness?
Contents
Mil thickness is a term used to measure the thickness of materials, specifically with one “mil” equaling one-thousandth of an inch (0.001 inches). When it comes to solar covers, the mil rating indicates how thick the cover is. The higher the mil number, the thicker the cover.
Why does thickness matter? The thickness of a solar cover significantly affects its performance in several key areas—heat retention, durability, and overall pool protection. A thicker cover is generally more effective at trapping heat, which keeps your pool warmer for longer periods. This can reduce the need for additional heating, saving you energy and lowering costs. However, a thicker cover is also heavier, which might make it harder to handle without the right tools, such as a cover reel.
In terms of durability, a thicker solar cover typically lasts longer than thinner options. This means fewer replacements over time, which can ultimately save you money. Thicker covers are also better at reducing evaporation and protecting your pool from debris, UV rays, and general wear and tear.
In summary, understanding solar cover mil thickness is essential when choosing the right cover for your pool. The thickness you select will impact not only how well your pool retains heat but also how long the cover lasts and how easy it is to use. Whether you need a lightweight cover for mild climates or a heavy-duty option for year-round protection, choosing the correct mil thickness will help you get the most out of your solar cover.

8 Mil Solar Covers: Ideal for Warm Climates
An 8 mil solar cover is the thinnest and lightest option available, making it a popular choice for regions with warm summers and short swimming seasons. These covers are designed for pool owners who need basic protection and heat retention without the added bulk and expense of thicker options.
Best for Warm Climates
If you live in an area where temperatures stay consistently warm and the swimming season is relatively short, an 8 mil cover could be ideal for your pool. It offers just enough heat retention to keep your pool comfortable during mild nights and sunny days, without the extra weight that comes with thicker covers.

It strikes an effective balance between the lightweight, less durable 8 mil options and the thicker, more expensive 16 mil covers.
Best for Moderate Climates
If you live in a region with moderate temperatures—neither too hot nor too cold—a 12 mil solar cover can provide just the right amount of heat retention without the bulk or cost of thicker options. It’s also ideal for pool owners who use their pools regularly but don’t need the maximum durability and protection that a 16 mil cover offers.
Pros:
- Good Heat Retention: A 12 mil cover retains heat better than its thinner counterparts, helping to keep your pool warm for longer periods, especially during cooler evenings.

Choosing the Right Mil Thickness for Your Pool
Selecting the right mil thickness for your solar cover is a key decision that can affect your pool’s heat retention, durability, and ease of maintenance. To make the best choice, consider a few essential factors such as your local climate, how often you use your pool, and your budget.
Key Factors to Consider: Climate, Pool Usage, and Budget
- Climate: Your region’s weather plays a significant role in determining the right cover thickness. Warmer climates may only require a thinner 8 mil cover, while cooler or windy climates will benefit from thicker options like 12 or 16 mil for better heat retention.
- Pool Usage: If you only use your pool seasonally or for short periods, a thinner, more affordable cover might be sufficient. However, for frequent or year-round pool use, investing in a thicker cover will pay off in terms of heat retention and durability.
- Budget: While thinner covers are cheaper upfront, they tend to wear out faster and need replacing more often. Thicker covers, although more expensive, offer longer-lasting protection and better energy savings in the long run.
How to Match Solar Cover Thickness to Your Local Climate
- Warm Climates: In regions with hot summers and mild winters, an 8 mil solar cover is often sufficient to maintain a comfortable pool temperature. Since natural heat is abundant, you don’t need heavy-duty heat retention, and the lightweight cover will be easier to manage.
- Moderate Climates: For areas with varying temperatures or cooler nights, a 12 mil cover strikes a good balance. It will help maintain your pool’s warmth while providing solid protection against environmental wear and tear.
- Cold or Windy Climates: For colder climates or regions with high winds, a 16 mil cover is the best choice. Its superior thickness will provide optimal heat retention, preventing water from cooling down rapidly, and its durability will protect your pool from debris and weather damage.
Budgeting: Upfront Cost vs. Long-Term Replacement Costs
- Thinner Covers (8 mil): Less expensive to purchase, but they have a shorter lifespan and may need replacing every few seasons. Consider this if you’re looking for a quick, budget-friendly solution but are prepared for more frequent replacements.
- Thicker Covers (12 and 16 mil): While the initial cost is higher, these covers tend to last much longer. Their durability reduces the need for frequent replacements, and their better heat retention can save you on heating costs, making them a better long-term investment.
Ease of Handling: Tips for Managing Thicker Covers
- Weight Consideration: Thicker covers, especially 16 mil, can be heavy and cumbersome. If you’re choosing a thicker cover, it’s a good idea to invest in a cover reel to make removal and application easier. This simple tool helps roll up the cover, saving you time and effort.
- Storage Tips: To prolong the life of your solar cover, store it properly when not in use. Avoid leaving it exposed to direct sunlight for extended periods, as UV rays can degrade the material over time.
- Use a Cover Reel: For thicker covers, especially 12 mil and 16 mil options, a cover reel is highly recommended. It simplifies handling, ensures smooth application and removal, and helps extend the cover’s lifespan by preventing unnecessary wear and tear.
In conclusion, choosing the right mil thickness depends on your climate, how often you use your pool, and your budget. Thinner covers work well for warm, seasonal use, while thicker covers are ideal for year-round, high-use pools in cooler or windy climates. Balancing your upfront costs with long-term savings, and ensuring ease of use with tools like cover reels, will help you select the best solar cover for your needs.
Benefits of Using Solar Covers for Your Pool
Using a solar cover for your pool offers a wide range of benefits that go beyond just keeping the water warm. These covers can significantly reduce evaporation, cut down on chemical use, and protect your pool equipment from harmful UV rays. Let’s take a closer look at the many advantages of using a solar cover.
How Solar Covers Reduce Evaporation
One of the most important benefits of a solar cover is its ability to reduce water evaporation. On hot days, a pool can lose a significant amount of water through evaporation, which means more frequent refills. By placing a solar cover on the pool’s surface, you create a barrier that limits water loss. This not only helps conserve water but also saves you time and money by reducing the need for constant top-offs.
Impact on Chemical Use and Water Conservation
Along with reducing water evaporation, solar covers help minimize the loss of pool chemicals. Chlorine and other chemicals dissipate more quickly when water evaporates. By keeping the water in the pool, a solar cover maintains the proper chemical balance, reducing the amount of chemicals you need to add. This not only saves money on chemicals but also helps protect the environment by reducing chemical runoff.
UV Protection for Pool Equipment
Solar covers also provide a layer of protection against the sun’s harmful UV rays. Prolonged UV exposure can damage pool equipment, liners, and other surfaces, leading to wear and tear over time. A solar cover blocks much of this UV radiation, helping to preserve the longevity of your pool equipment and reducing maintenance costs.
How Solar Covers Enhance the Longevity of Your Pool
By reducing evaporation, conserving chemicals, and protecting pool surfaces from UV damage, a solar cover enhances the overall lifespan of your pool. With less wear and tear on both the water and the equipment, you’ll experience fewer issues and less maintenance over time. This makes solar covers a valuable investment for pool owners looking to save money, time, and effort while enjoying a longer-lasting pool.
In conclusion, using a solar cover offers numerous benefits that improve water conservation, reduce chemical usage, protect equipment, and ultimately extend the life of your pool. Whether you’re looking to save on pool maintenance or minimize environmental impact, a solar cover is an essential tool for any pool owner.
Conclusion:
Choosing the right solar cover mil thickness is essential for balancing your pool’s heat retention, durability, and ease of use. If you’re in a warmer climate, an 8 mil cover may be all you need. For cooler or windy areas, investing in a 16 mil cover will provide the long-term protection and heat retention your pool requires. By considering your climate, pool usage, and budget, you can find the perfect solar cover to protect your pool while saving energy and extending its life. Ready to enhance your pool’s performance?
