Cool Area Sun Shade Sail 6x20 ft Rectangle - Clean UV Shade

In this review of the Cool Area Sun Shade Sail 6x20 ft rectangle, the bottom line is simple: this is a practical, no-frills shade cover for homeowners who want reliable sun protection over a patio, deck or poolside area. The strongest reason to buy is the dense 100% new HDPE fabric that blocks up to 95% of UV and provides an 85%-90% shading rate, creating noticeably cooler outdoor spaces while resisting fraying thanks to reinforced stitched seams. Installation requires planning for accessory space, but once mounted the sail delivers solid coverage and a neat, unspliced appearance.

Key Features

• Full-panel construction: The sail is made without splicing seams, offering a cleaner look and uninterrupted shading performance over the full 6x20 ft panel.
• High-density HDPE fabric: Made from 100% new HDPE, the fabric provides up to 95% UV protection and an 85%-90% shading rate to reduce heat under the canopy.
• Reinforced edges: All edges are double-stitched to prevent frayed edges and keep the sail from losing shape over time.
• Stainless steel D-rings: Durable rust-proof D-rings at each corner simplify attachment and help the sail withstand outdoor conditions.
• Accessory allowance: The sail requires leaving 0.5-1 ft of space for mounting hardware, and the fabric has a tolerance of about 4 in due to elasticity.

Who It's For

The Cool Area 6x20 ft sail is best for homeowners with a long rectangular area to cover, such as a narrow patio, side yard, or poolside walkway who want a continuous, aesthetic shade without visible seams. It suits DIY installers who can plan anchor points allowing the recommended 0.5-1 ft clearance for turnbuckles, hooks or pole fittings.

Those who need fully wind-rated engineered solutions or who expect to leave the sail up through severe weather should consider a heavier, professionally engineered canopy. Also measure precisely if you need exact fitting; the fabric elasticity and 4 in tolerance mean custom trimming or tight-fit installations may be challenging.

Pros & Cons

Pros

• High-density 100% new HDPE provides excellent UV protection and cooling benefit.
• No splicing seams gives a clean look and consistent shade across the entire panel.
• Reinforced stitched seams and stainless steel D-rings improve durability and ease of installation.
• Works well over patios, decks, carports and pool areas for immediate sun relief.

Cons

Specifications

Our Verdict

The Cool Area 6x20 ft rectangle shade sail is a strong value for anyone who needs a long, continuous shade cover that looks tidy and reduces sun and heat effectively. It is especially good for patios, decks and poolside areas where a non-spliced panel and reinforced edges matter. Buyers should plan anchor spacing to accommodate the accessory allowance and be aware that extreme weather may require taking the sail down for longevity.

Frequently Asked Questions

How much space do I need for mounting?
You should leave 0.5-1 ft of space for accessories such as turnbuckles or hooks so the sail can be tensioned properly.

Will the color fade in direct sun?
Customers report good color retention, but like all outdoor fabrics some gradual fading can occur over long-term direct exposure.

Is the fabric durable in wind?
The reinforced seams and stainless D-rings help, and many customers find it holds up well, but very strong or prolonged high winds may shorten service life and removal in storms is recommended.
