17 ft x 20 ft Turquoise Rectangle Sun Shade Sail - UPF50 Cool Canopy

Our review of the ShadeMart 17' x 20' Turquoise Sun Shade Sail finds it best for homeowners and small-business owners who need a durable, breathable canopy that reduces heat and blocks strong sun. The single biggest reason to buy is the fabric performance: woven HDPE construction that is water permeable yet blocks up to 95% of harmful UV, delivering noticeable cooling for patios, carports, and poolside areas. Installation is straightforward with stainless steel D rings and heavy duty webbing, and the sail's rectangle shape makes layout and coverage predictable.

Key Features

• Material: Woven HDPE fabric keeps the canopy breathable while resisting UV degradation for long-lasting outdoor use.
• UV Protection: UPF50 rated fabric blocks up to 95% of harmful UV rays, lowering surface temperatures by an estimated 10 to 15 degrees for more comfortable outdoor time.
• Hardware: Stainless steel corner D rings attached to heavy duty white webbing provide secure anchor points and improved longevity at connection points.
• Water Permeable: The sail allows water and air to pass through, preventing pooling and reducing wind load compared with solid tarps.
• Custom Fit: Available in multiple sizes and custom options so buyers can match the sail to patios, pergolas, carports, and pool areas with accurate measurements.

Who It's For

The ShadeMart rectangle shade sail is ideal for homeowners, renters with permission to anchor to existing structures, and small businesses that want a low-profile shade solution for patios, outdoor seating, and carports. Its breathable HDPE fabric and stainless steel D rings suit installations where water permeability and corrosion resistance are important.

Those who need a fully waterproof shelter, a freestanding umbrella, or a hard-roof structure should look elsewhere, since this style is not waterproof and relies on proper mounting points such as walls, poles, or trees for full performance.
